LESSON 1

NO TRUMP BIDDING

General Considerations:

a. Strength ‑ High cards points only (never distribution) are counted. The presence of a

5-card suit is worth one point, and the presence of tens can also be taken into

account. The system is based upon 26 HCP's = Game, 34 HCP's = Small

Slam, and 37 HCP's = Grand Slam.

b. Distribution ‑ Only balanced hands; i.e., no voids, no singletons, and not more than one

doubleton, qualify. (Examples: 4‑3‑3‑3, 4‑4‑3‑2, 5‑3‑3‑2)

(1) The 5‑card suit is rarely a Major suit.

(2) Distributional exception: (5‑4‑2‑2) Where the two doubletons are Major suits

headed by an Ace or a King (Example: KX AX KJXX AQXXX).

c. Location Of Strength ‑ The concentration of honors, presence of any tenaces (AQ, KJ, etc.),

or the holding of a worthless doubleton are rarely considered.

OPENING NO TRUMP BIDS

a. 0‑12 HCP’s ‑ Pass

b. 13‑14 HCP's ‑ Bid one of a preferred Minor and rebid 1NT

c. 15‑17 HCP’s ‑ Bid 1NT

d. 18‑20 HCP’s ‑ Open one of a Minor and jump to 2NT with 18 or 19 HCP’s & 3NT with 20 HCP’s

e. 21‑22 HCP's ‑ Open 2NT

f. 23‑24 HCP’s ‑ Open “2C”(Strong, Artificial, and Forcing) and rebid 2NT

q. 25‑27 HCP's ‑ Open "2C" (Strong, Artificial, and Forcing) and jump to 3NT

h. Gambling "3NT" ‑ Holding a 7‑Card self‑sufficient Minor suit (Example: AKQXXXX )

If partner has stoppers in both Majors and two (2) quick tricks or better,

he/she passes. Alternatively, he/she) bids "4C" (The pre‑arranged

escape) and opener either passes or bids "4D" to escape the doomed

3NT gamble.

RESPONSES TO OPENING 1 NT WITH DESIRE TO REMAIN IN NO TRUMP

a 0‑8 HCP's ‑ Pass

b. 9‑10 HCP's ‑ Bid 2NT ‑ Invites Partner to Pass with a minimum (15 HCP's) or to bid

3NT with a maximum (16 or 17 HCP's)

c. 11‑15 HCP's ‑ Bid 3NT

d. 16‑17 HCP's ‑ Bid "4NT" (Quantitative) Invites partner to Pass with a minimum (15

HCP's), or to bid 6NT with a maximum (16‑17 HCP's) Note: "4NT" is not

Blackwood in this sequence. Must use Gerber ("4C") to ask for Aces.

e. 18‑19 HCP's ‑ Bid 6NT

f. 20‑21 HCP’s ‑ Bid "5NT" (Quantitative) Requesting partner to bid 6NT with a minimum

of (15 HCP's) and to bid 7NT with a maximum of (16‑17 HCP's)

g. 22‑23 HCP's ‑ Bid 7NT

- 2 -

RESPONSES TO OPENING 1 NT WITH DESIRE TO DEVIATE FROM NO TRUMP

a. “2C” ‑ Stayman Convention asking for a 4‑Card Major. (“3C”over a 2NT opening)

b. “2D”, “2H”, “2S”, or “3C” ‑ Jacoby Transfer (Alertable) bids.(“3D”, etc. over a 2NT opening)

c. “3D” - An invitational bid (Seeking 3NT) with a 6‑Card Minor suit headed by two of the

top three honors and fewer points than would normally elicit game.

d. 3H or 3S ‑ A game force bid holding a 5‑Card Heart or Spade suit, respectively.

e. “4C” ‑ The Gerber Convention, an artificial system, asking for Aces.

f. 4H or 4S ‑ A close‑out bid with a 6‑Card suit. (Opener can have no fewer than two)

g. 5C or 5D ‑ A close‑out bid with a freak hand holding a long broken Minor suit, probably

seven or eight cards in length, with little additional outside honor strength.

A ONE NO TRUMP OVERCALL

(1) In the direct position. (2nd position relative to the opponent's opening bid of one of a suit) ‑

Shows an equivalent hand to a 1NT opening bid with the added feature of at least one, and

preferably two, stoppers in the opponent's opening previously bid suit.

(2) In the balancing position (4th position relative to opponent's opening bid of one of a suit) -Shows about 10‑13 HCP's with at least one stopper in the opponent's opening suit.

A TWO NO TRUMP OVERCALL

(1) Over a 1H, 1S, or 1NT opening bid ‑ Shows a Minor two‑suited hand with at least a 5‑5

distribution ("UNUSUAL NT"). The minimum strength may vary according to

the vulnerability. At favorable vulnerability, a 7‑8 HCP hand would be considered adequate.

At unfavorable vulnerability, both the hand and the suits should be distinctly stronger.

(2) Over a pre‑emptive opening 2‑Bid ‑ Shows an opening 1NT (15‑17 HCP) hand with at least one, and preferably two, stoppers in opener's pre‑emptive bid suit.

A ONE NO TRUMP RESPONSE TO AN OPENING OF ONE OF A SUIT

6‑10 HCP's ‑ No support for partner's suit and no 4‑Card Major suit having been by‑passed. This bid is of great pre‑emptive value by prohibiting the fourth player from bidding at the one‑level.

A TWO NO TRUMP RESPONSE TO AN OPENING BID OF ONE OF A SUIT

(1) Over a Minor suit opening bid ‑ Shows 11‑12 HCP's ‑ An invitational bid which can be passed. It denies holding a 4‑card or better suit in either Major.

(2) Over a Major suit opening bid ‑ Shows 13‑15 HCP's ‑ Denies support for partner's suit.

A THREE NO TRUMP RESPONSE TO AN OPENING BID OF ONE OF A SUIT

(1) Over a Minor suit opening bid ‑ Shows 13 ‑15 HCP’s which denies a 4‑Card or better suit in either Major.

(2) Over a Major suit opening hid ‑ Shows 16‑18 HCP's and denies support for partner's suit.

LESSON 2

OPENING BIDS WITH UNBALANCED HANDS AND REBIDS BY THE OPENER

(Unlike No Trump Bidding, Does Include Distributional Points)

A. OPENING 1 OF A SUIT:

0‑12 HCP’s Pts. = Pass unless Rule of 20 Satisfied in 1^st and 2^nd positions

13 HCP’s Pts. = Should open since Rule of 20 will always be satisfied

14‑15 HCP’s Pts. = Must open 1 of a suit and then rebid:

(a) 1 No Trump

(b) 2 of one's own suit (if a 5-card or better Minor or a 6-card or better Major)

(d) Pass, but ONLY if there occurs an intervening bid by opener’s RHO (Right-hand opponent)

(e) Pass ONLY if partner has limited the combined partnership potential via one of only

two limiting bids; i.e., either 1NT or 2 of opener’s bid suit

16‑18 Pts. = Must open 1 of a suit and then rebid:

(a) Jump in opener’s own suit

(b) Jump in Partners suit; i.e., raise him/her two levels of bidding

2H 3C

19 Pts. or more = Open 1 of a suit and jump-shift into a second suit

B. OPENING 2 OF A SUIT: (“2C”= strong, artificial and forcing)

when weak two’s (2D,2H,2S) are otherwise used)

25 or more Pts. with a 5‑card suit

23 or more Pts. with a 6‑card suit

21 or more Pts. with a 7‑card suit

- 4 -

C. OPENER"S REBID: The second bid (the so‑called "rebid") by the opener, subsequent to his/her opening of one of a suit, is frequently the crucial point in any auction. It is the first opportunity for opener to more finitely describe his/her hand and becomes the basis by which responder can then proceed.

(1) AFTER A ONE‑OVER‑ONE RESPONSE FROM PARTNER:

Examples: 1C P 1D P (or) 1D P 1H P

?? ??

(A) A Rebid of 1NT [1D - 1H - 1NT] = (11-14 HCP’s and a balanced hand)

(B) A Rebid of opener's original suit [1H ‑ 1S‑ 2H] = (11‑15 Points and a 6‑Card suit)

Promises 11‑18 Points)

(D) A Rebid of a lower ranking suit at the 2‑level [1H ‑ 1S ‑ 2C] = (Since 1NT was

by-passed, this usually shows a 2‑suited hand)

(E) A Reverse; i.e., a rebid of a higher ranking suit at the 2-level [1C ‑ 1H ‑ 2D] =

Usually 16‑18 Points and is encouraging but not forcing)

(F) A Single raise in responder's suit [1H ‑ 1S ‑ 2S] = (11‑15 Points and at least a

4‑Card support for responder’s bid suit)

(G) A Rebid of 2NT [1H ‑ 1S ‑ 2NT] = (18‑19 HCP's and a balanced hand)

(H) A Jump rebid in opener's suit [1D ‑ 1H ‑ 3D] = (At least a 6‑card suit and at least

16‑18 HCP’s)

(I) A Jump raise in responder's suit [1D ‑ 1H ‑ 3H] = (16‑18 points and at least a

4‑card support for responder’s bid suit)

(J) A Rebid of 3NT [1H ‑ 1S ‑ 3NT] = (20 HCP's and a balanced hand)

(K) A Jump‑shift rebid [1D ‑ 1H ‑ 3C] = (An unbalanced hand with at least 19 Points

and is game-forcing)

(L) A jump to game in responder's Major suit [1H ‑ 1S ‑ 4S] = (A 4‑Card support and

game values)

(M) A jump to game in opener's Major suit [1H ‑ 1S ‑ 4H] = (At least a 7‑Card suit

and game values)

(2) AFTER A TWO‑OVER‑ONE RESPONSE FROM PARTNER:

Examples: 1H P 2D P (or) 1D P 2C P

?? ??

(M) A Rebid of 2NT [1H ‑ 2C ‑ 2NT] = (An unbalanced hand with 11-14 Points – Is

Invitational to GAme

(N) A Rebid in opener's suit [1D ‑ 2C ‑ 2D] = (A minimum opening bid with a 6‑Card

or a very good 5‑Card suit)

(O) A Rebid in a lower ranking suit [1S ‑ 2C ‑ 2D] = (13‑15 Points and is not forcing)

(P) A Single raise in responder's suit [1H ‑ 2D ‑ 3D] = (A minimum non-forcing rebid)

(Q) A reverse at the 2‑level [1H ‑ 2C ‑ 2S] = (A game-forcing bid with the first bid

suit equal or longer than the second bid suit)

(R) The rebid of a second suit at the 3‑level ("A HIGH REVERSE") [1H ‑ 2D ‑ 3C]

(A game forcing bid evidencing at least 16 HCP’s)

(S) A jump shift to the three level [1S ‑ 2C ‑ 3D] = (A game-forcing bid approaching

Slam)

(T) A jump rebid in opener's suit [1S ‑ 2D ‑ 3S] = (Shows a 6‑Card suit and 16‑18

Points)

(U) A jump raise in responder's suit [1S ‑ 2C ‑ 4C] = (Forcing and presumably a

4‑card or 5‑card support) [1S ‑ 2H ‑ 4S] = (Shows a hand slightly too good for

a 3H rebid and may be as little as a 3‑card support since responder has

promised a 5‑card suit)

(V) A jump to game in opener's suit [1S ‑ 2D ‑ 4S] = (A strong 6‑Card or better suit

and no interest in no Trump or responder’s suit)

(W) A 3NT rebid [1D ‑ 2C ‑ 3NT] = (Equivalent to a 2NT rebid over a one‑over‑one

level response; i.e., a 18‑19 HCP opening with a balanced hand)

LESSON 3

PRE-EMPTIVE BIDDING

A. DEFTNITION: An opening bid of two or more with a hand containing both a long suit and

a sub‑minimum high-card strength (5-11 HCP’s) The bid is usually

defensive in purpose. The pre‑emptive bidder hopes that the hand belongs to

the opponents with the stronger hands and that they find it difficult to bid

accurately when the auction has started at a higher level with one or more

bidding levels have been previously consumed by the pre-emptive bid.

B. POSITIONAL CONSIDERATI ONS:

The third player seat in the auction is in the best position to make an opening pre‑empt. He/she knows that such a bid cannot pre-empt the first position player since that partner has already limited his/her hand by passing. The fourth player is almost sure to have the best hand at the table. Since partner's initial pass makes game unlikely, a sub‑minimum pre‑empt is often very effective.

Next to third chair, pre‑emptive bids by the dealer are the most attractive. Although they may present difficulty to partner, there are two opponents who may have good hands, and the odds favor that the hand belongs to the opponents.

Second chair is least desirable for opening a pre‑emptive bid. One opponent has already passed; therefore, the odds are no longer two to one in favor of the opponents having a good hand. Hence, marginal pre‑empts should always be avoided in second position; i.e., they should be slightly stronger than pre‑empts by the dealer and by the third positioned player.

When opening a pre‑empt in fourth chair, one obviously expects to get a plus score, otherwise one would simply pass the deal out for no score to either side. Therefore, fourth chair "pre‑empts" generally suggest the values of a minimum opening one‑bid both offensively and defensively.

C. INFLUENCING FACTORS:

(1) LENGTH OF SUIT ‑ A pre‑emptive or weak 2‑bid is usually with a 6‑card suit, a weak 3-

3-bid is with a 7‑card suit, and an opening 4‑bid is usually with an 8‑card suit.

(2) POSITION AT THE TABLE ‑ Already discussed.

(3) STRENGTH OF SUIT ‑ The best pre‑empts have a concentration of honor strength in the

bid suit. This automatically increases his/her playing strength, decreases the

danger of suffering a substantial penalty, and decreases the chance of a successful

defense against an the opponent’s presumed contract. Weak 2‑Bids usually have 5‑11

HCP’s in strength; weak 3‑Bids have about 6‑10 HCP's.

- 7 -

(4) VULNERABTLTTY ‑ With favorable vulnerability; i.e., when not vulnerable against

vulnerable, the pre‑emptive bid should be within three tricks of the bid within one's

hand. With equal or unfavorable vulnerability, the bid should be within two tricks of

the call. The best way to count winners in pre‑emptive type hands is by counting

losers and subtracting them from thirteen.

D. RESPONSES TO A WEAK 2‑BID:

(1) "RONF": (“Raise‑Only‑Non‑Force”) ‑ A raise of partner's pre‑empt bid by one or more

levels. Such a bid is not forcing, but rather an attempt to further the obstruction of the

opponents who are seen to have the preponderance of points. It obviously guarantees

two or more pieces in partner's pre‑empt suit.

(2) “2NT”: (An artificial and forcing convention asking for a further description of partner's

hand.) The invoking 2‑NT bidder must have better than an opening hand since the

pre-empting partner has evidenced a weaker than opening strength. The responses to

same are all artificial are declare the following in their responses:

a. "3C" = 5‑7 HCP's and l of the top three honors.

b. "3D" = 5‑7 HCP's and 2 of the top three honors.

c. "3H" = 8‑11HCP's and 1 of the top three honors.

d. "3S" = 8‑11HCP's and 2 of the top three honors.

e. "3NT"= 8‑11HCP's and 3 of the top three honors.

(3) The Bid Of Any New Suit: (A strong forcing bid of a better than opening hand with at

least a 5-card suit in the newly-mentioned suit ) Such a bid asks for one of the

following three responses, and no other response:

a. Raise the responder's suit one level with three pieces.

b. Bid cheapest NT with two of responder’s suit.

c. Re‑bid opener's suit with one or none of responder's suit.

Responder will then place the contract based upon opener's answers to either (2) or (3) above.

E. RESPONSES TO A WEAK 3‑BID: ‑ Responder should bend over backwards to play in

opener's suit, for if one elects to play the contract elsewhere, the dummy is unlikely to be

very useful.

(1) 3NT: ‑ A Sign-off. (Opener MUST pass)

(2) A Raise To Game in the pre-empt suit is either pre‑emptive in of itself, or made with game-

going values.

(3) Game Bids In a New Suit are a Sign-off. (Opener MUST pass)

(4) Jumps to Five of Opener's Suit (Majors only) are slam tries asking about the quality

of opener's trump suit. (With no more than one likely loser in trumps, opener

accepts and proceeds to Slam, else passes.

LESSON 4

THE DRURY CONVENTION

A. BACKGROUND: After two previous passes at the table, the third player may sometimes opt to open the bidding relatively freely; i.e., with several HCP's less than that normally required. This is partly because of the negation of the responsibility of a rebid (partner has already passed), partly because the bid made may inconvenience the forth player who has yet to have the opportunity to open the bidding (the player who is likely to have the best hand at the table), and partly because partner may utilize the information for lead directing significance should that team ultimately become defenders of an eventual contract by the opponents.

In third seat, after two successive passes, one may open with any holding which would otherwise be good enough to be a sound overcall (even as low as 8‑9 HCP's). If the answer to the question, "IF MY RIGHT‑HAND OPPONENT WOULD HAVE OPENED 1‑CLUB, USING THE SUIT QUALITY TEST, WITH THIS HOLDING, WOULD I HAVE WANTED TO OVERCALL?", is yes, one should open the hand in third seat.

SUIT QUALITY TEST ‑ A suit is strong enough for an overcall if‑ THE LENGTH IN THE SUIT + THE NUMBER OF HONORS IN THAT SUIT (THE JACK AND TEN ARE COUNTED AS HONORS IF HIGHER HONORS ARE ALSO HELD) = THE NUMBER OF TRICKS TO BE BID. Thus, if the suit quality = seven (7), the hand would qualify for a super‑light third seat opening bid at the one‑level.

XX AQXXX AKQX

EXAMPLES: AKlOXX KIOX XXX

(a) QXX (b) XX (c) XXX

XXX QXX QXXX

In third seat, players who use a 5‑card major system are likely to open 1H with (a), and 1S with (b & c). Their reasons are simple. They want to direct the lead if they become defenders, and their opening pre‑empts most of the bids at the 1‑level from their opponents. In addition, they are not afraid of being raised on 3‑card support with the 5-card holding as in (a) or (b) above, or even such a fine 4‑card suit as in (c).

In forth seat, after three successive passes, the same principal of opening with a less than sound opening also applies, especially, when the RULE OF 15 (Lesson 15), is employed.

NOW LET US TURN OUR ATTENTION TO THE OTHER SIDE OF THE TABLE.

B. PURPOSE: After passing, the responder to a third or fourth‑chair opening bid faces two special problem in describing his/her hand:

(1) A simple change of suit is no longer forcing (opener knows responder has less than

opening values), so responder cannot make a temporizing bid; opener my pass.

(2) The opener may well have opened the bidding on a sub‑minimum hand so that a jump

response by responder could easily get the partnership too high.

- 9 -

Suppose you pick up (JXX AXX KQXXX JX) and after passing, partner opens 1S in third or forth chair. What response do you make? Does partner have a full opening count or perhaps a third-position sub-minimum 10-12 HCP’s? If you just raise to 2S it is an underbid, and if partner has a 14‑15 point true opening bid, opener would pass and you could be playing in a final inferior part‑score contract. If , on the other hand, you bid 3S, and opener has a hand as in (b) or (c) above (a sub‑minimum opening), 3S is likely to be too high. In short, responder does not have a good bid available which will describe the maximum previously-passed hand with support for opener's suit. Determining the nature (full or sub‑minimum) of partner's third or forth seat opening is crucial in finding the best level of the final contract. Utilizing the Drury Convention enables responder to show his/her fit and values WITHOUT jumping to the 3‑level.

C. REQUIREMENTS: To use the Drury Convention, the responder must have both:

a. A previously passing 10‑12 point hand (one just short of the values needed for a minimum

opening bid) and:

b. Either: (1) A fit for opener's Major suit third or forth‑seat opening bid or,

(2) A good 6‑card Club suit that responder expects to rebid irrespective

of opener's response to the Drury Convention.

D. INVOKING THE CONVENTION: Responder bids an Artificial "2C" in response to a third or forth chair opening bid. This 2‑Club response does NOT say anything about responder's Club holding (unless Clubs are subsequently rebid by responder); but simply asks opener whether or not he/she has a full opening bid.

E. RESPONSE BY OPENER: Opener's primary obligation is to inform responder as to whether or not a full opening bid is present. The Rebids by the responder are as follows:

1. "2D" ‑ An Artificial response denying a full opening bid thus evidencing a sub‑minimum

opener. This bid, being artificial, says nothing about opener's Diamond suit.

2. 2H or 2S ‑ A repeat of opener’s suit evidencing a full opening count.

3. 3C or 3D ‑ A natural rebid with more than full values for the original 1H or IS opening.

4. 3H or 3S ‑ A game-force and slam-interest opening hand with.

F. RESPONSE BY RESPONDER: Responder, knowing the sub‑minimum, normal, or slam interest value of opener's hand, now takes control and either bids:

1. 2H or 2S ‑ in response to the artificial "2D" response by opener denying a full

opener.

2. 3C ‑ A drop dead 6‑card Club suit with no support for partner's stated Major suit.

3. 3H or 3S ‑ Invitational to game

4. 4H or 4S ‑ A sign‑off in response to opener's full opening bid.

G. SIGNIFICANCE OF RESPONDER’S BID OTHER THAN "2D”: Since responder is a previously-passed hand, his/her bid is not forcing and can be passed. opener is, therefore, relieved of his/her normal obligation of an opening bidder to keep the bidding open by rebidding something.

H. OPENER'S RESPONSE TO "2C" AFTER INTERFERENCE BY THE OPPONENTS: A pass should signify a sub-minimum opening and anything else signifies a full normal opening bid.

LESSON 5

THE “MICHAEL’S CUE-BID” CONVENTION

A. BACKGROUND: Two‑suited hands are generally difficult to describe after the bidding has

been opened by the opponents, especially if the hand is very weak. Often, the opponents bid

too much too soon for both of the suits to be safely shown, or the bidding dies too soon for

both suits to be introduced. The Michael's Cue-Bid describes such a two‑suited hand by

means of a simple artificial cue‑bid overcall. It is both a defensive obstructive call, either in

an attempt to pre-empt the opponent's bidding space, or to lead to a profitable sacrifice against

their eventual contract, or else an offensive weapon used to seek the best suit for a sought-after

makeable contract by the invoking partnership. The Michael’s Cue-bid Convention serves as

a valuable weapon in one's competitive bidding arsenal.

B. DEFINITION: The Michael's Cue‑bid uses a direct cue‑bid of the opponent's suit as a two-

suited take-out bid. It promises at least a 5‑5 or better distribution in each of two suits (With

a 6‑4 distribution, one is best advised against invoking Michael’s).

1. 1C “2C” = BOTH MAJORS (At least 5-H and 5-S, or better)

2. 1D “2D” = BOTH MAJORS (At least 5-H and 5-S, or better)

3. 1H “2H” = THE OTHER MAJOR + AN UNSPECIFIED MINOR (Either 5-S

and 5-C, or 5-S and 5-D, or better)

4. 1S “2S” = THE OTHER MAJOR + AN UNSPECIFIED MINOR (Either 5-H

and 5-C, or 5-H and 5-D, or better)

5. 1H “2NT” = BOTH MINORS (At least 5C‑5D, or better) (The “Unusual NT"

Convention; i.e., the two lower un-bid suits)

6. 1S “2NT” = BOTH MINORS (At least 5C‑5D, or better) (The “Unusual NT"

Convention, i.e., the two lower un-bid suits)

________________________________________________________________________

7. 1C “2NT” = THE TWO LOWER UN-BID SUITS, in this case Diamonds and

Hearts, 5-5 or better)

8. 1D “2NT” = THE TWO LOWER UN-BID SUITS, in this case Clubs and

Hearts, 5-5 or better)

C: REQUIREMENTS: - 11 -

1. Distribution: ‑ At least a 5‑card or better holding in each of two unbid suits.

2. Strength ‑ The strength of the hand when Michael’s cue-bid is used falls into one of

two types. Either one that is very weak, 0-10 HCP’s; else one that is very

strong, 16 HCP’s or more. When the hand is of moderate value, 11-15

HCP’s, one should bid the higher-ranking suit first, followed by a rebid of

the lower-ranking suit on the next bidding turn. In this way, responder

can differentiate the point count of the invoking Michael’s cue-bid user.

( See (E.) Below )

Examples: The opponents have opened 1C and you hold the following:

QJ109X KXXXX XX X (bid “2C”and then pass partner’s 2H or

2S response)

AK109X AKJXX KX X (bid “2C”and then “3C” over partner’s 2H

or 2S response)

AQ109X KJXXX AX X (bid 1S and then rebid 2H at your next

bidding opportunity)

3. Vulnerability and Level ‑ The more adverse these conditions, the more desirable are either a

greater strength and/or a longer distributional holding.

D. RESPONSES TO MICHAEL’S CUE‑BID: The partner of the Michael's Cue‑bid should, if

at all possible, when the bidding permits, take a preference for one of the suits shown by the

cue‑bidder. Since partner will have as few as five in each of his/her suits, a 3‑card support is

more than adequate. A preference on a doubleton, however, will sometimes be necessary,

unless responding partner has a 6-card or better fourth suit.

Examples:

(a) 1C “2C” P 2H (A preference for Hearts)

(b) 1D “2D” P 2S (A preference for Spades)

(d) 1S “2S” P 3H (A preference for Hearts)

(e) 1H “2H” P “2NT” (A preference for the

as‑yet-unspecified Minor as opposed

to the alternate Major)

P 3C/3D (The unspecified Minor is revealed)

(f) 1S “2NT” P 3C/3D (A Minor suit preference is chosen)

(g) 1S “2NT” P 3H (Responder denies request to choose Clubs or Diamonds and, instead chooses his/her 6-card Heart suit.

E. REBIDS BY CUE-BIDDER:

(a) (With 0-10 HCP’s) – Pass Chosen Suit by Responder

(b) (With 16+ HCP’s) - Cue-Bid Opponent’s Suit Once Again!

LESSON 6

RESPONSES TO PARTNER’S TAKE-OUT DOUBLE

(Refer to Lesson 6 ‑ Last Year)

(For Collateral Information)

A. CIRCUMSTANCE: The opponents have opened with one (1) of a suit. Your partner says:

"DOUBLE". Your partner thereby evidences an equivalent or better hand in comparison to the opening bidder. Since you have not yet made a call, your partner’s double is for a take-out. The partner of the opener passes, and it is your turn to bid. What are the appropriate bids in response to your partner's take‑out double and what do they signify to the doubler? Can the responder to the doubler pass, and if so, under what conditions? What if there is an intervening bid by the partner of the opening bidder? Does this mitigate the need for doubler’s partner to act?

B. DEFINITION: A TAKE‑OUT DOUBLE IS A DEMAND ONE ROUND FORCE ON PARTNER UNLESS THERE IS AN INTERVENTNG BID BY THE OPPONENTS. IF NO INTERVENING BID OCCURS, THE DOUBLER’S PARTNER MUST BID (One Exception, later noted in [3(f )] ), EVEN IF, WORST CASE SCENARIO, HE/SHE HAS AS LTTTLE AS 0 HCP’S.

C. TYPES OF RESPONSE: There are basically three (3) types of responses to take‑out doubles: 1) NEGATIVE (weak); (2) POSITIVE (constructive); and (3) GAME‑FORCING or GAME‑INVTTATIONAL (strong).

(1) NEGATIVE (WEAK): (0‑8 HCP's) ‑ Mention one's best (usually longest) suit amongst those requested with preference given to the unbid Major(s).

(a) 0‑5 HCP's ‑ Responder must bid in the absence of an intervening bid

by the partner of the opening bidder, else may pass.

XXX QXXX QJXXXX XX XXX (2C)

(b) 6‑8 HCP's ‑ Responder should bid even if there is an intervening bid by the

opponent.

If there is an intervening bid by doubler’s partner’s RHO (opener’s partner), and if responder to the double has 0‑5 HCP's, it removes the obligation of doubler's partner to respond. Therefore, if, in the presence of an intervening response by opener's partner, doubler's partner DOES bid, it is because he/she WANTS TO, not because he/she MUST do so. In bridge terminology, this is called a "free bid".

RESPONSES OVER THE OPPONENT’S TAKE-OUT DOUBLE

A. CIRCUMSTANCE: Your partner has opened the bidding with one (1) of a suit and

your right hand opponent (RHO) has bid a take‑out double. What

should be your response, and what are the various meanings of that

which you might call?

B. TYPES OF RESPONSES: Basically there are three types of responses necessary under

these circumstances; i.e., the ability to show (1) a weak pre-emptive

holding, (2) a mildly constructive competitive holding, and (3) a

strong, invitational or better holding.

C. CONDITIONS: Two conditions need be examined under which the three previous responses (weak, mildly competitive, and strong) need be exercised; (1) with trump support for partner, and (2) without trump support for partner.

With Trump Support

(1) WEAK OR PRE‑EMPTIVE: ‑ (0-5 HCP’s)

(A). A Single Raise of Partner's Suit with slightly weaker values necessary

without the opponent’s intervening double; i.e., 0‑5 HCP's.

LESSON 8

BALANCING

A. DEFINITION: ‑ The bidding of partner's cards in the reopening position, (The so‑called

"PASS-OUT SEAT”, or 4th seat relative to the last previous call or bid

other than a pass) is commonly called "BALANCING". It is called this

because the bidding presumes that the partner has the balance of strength.

This presumption is based upon the the opponent's bidding (or, in this case,

the lack thereof) and the points the player in the forth chair is NOT looking

at in his/her own hand.

Example‑ (1C/1D/1H/1S) P P ???

The use of balancing bids will be a source of considerable profit to a

partnership when used properly in situations in which the opposing bidding has stopped at

a low level and where the bidding would otherwise cease. In order to balance effectively,

however, it is extremely necessary to make and understand adjustments in the meaning of

such competitive tools such as doubles, overcalls, no‑trump bids. cue‑bids, and jump-

overcalls. Such tools all have altered meanings when used in the balancing position.

B. BALANCING DOUBLES: ‑ A balancing double does not promise the same strength and distribution as does a direct take‑out double. One may make a balancing double with as few as 8‑9 HCP's along with any reasonable holding and support for the unbid suits.

Suppose, for example, a 1H bid is passed around to you in the fourth seat (balancing chair), and you hold any of the following hands: In all three examples, one should "DOUBLE".

NOTE: ‑ If 1H were bid to your immediate right, one

(a) KJIOX X KlOXX AQXX would have doubled with (a), overcalled 2D with (b),

(b) KX XX AKQJX JlOXX and passed with example (c). In the balancing seat,

then clarifying exactly which of the three one holds

via the rebid. Thus, if partner does not convert your double to a penalty double by passing; i.e., if partner had previously "TRAP-PASSED", but instead, for example, alternatively bids 1S, you would respond as follows: With

(a) you will raise to 2S suggesting values for any direct take‑out double.

(b) you will rebid 2D indicating that you had had a good 2D overcall but elected to double in case partner was "TRAPPING".

- 18 -

C. RESPONSES TO BALANCING DOUBLES: ‑ The response to a balancing double requires better judgment than does bidding over partner's direct take‑out double. Remember, partner may have made a balancing double on a much wider range of hands; i.e., he/she may not have good support for ail of the unbid suits, and the strength of his/her hand may be considerably below the values required for a direct take‑out double.

(1) A bid of any unbid suit at the cheapest level = 7‑11 HCP's.

(2) Any jump response = a hand with opening strength, previously passed.

(3) A jump to 2NT = A good opening bid with opener's suit well‑stopped.

(4) A jump to 3NT = values for a strong 1NT opening with opener's suit under

control.

D. BALANCING OVERCALLS: ‑ A constructive alternative to the balancing double is a

balancing overcall. As with a balancing double, a balancing overcall does not require the same strength and suit quality that is necessary for a direct overcall.

1H P P ???

Examples: (a) JXXXX XX AJ10X Q10 Note: None of these hands meet

(b) J10 XXX KXXXXX A10 the standard requirements for a

appropriate balancing overcalls

Frequently, one, will be forced to balance at the one‑level even with a 4‑card suit.

1D P P ???

Examples: (a) KJXX QX XXX QXXX (1S)

(b) X AXXX JXXX AXXX (1H)

When one balances with an overcall, partner should not get overly enthusiastic. Balancing overcalls are usually the weakest of the actions one may exercise in the balancing chair, and, as noted above, can even be done with a weak hand, a poor suit quality, and even with a 4‑card suit. Even if the previously-passed partner holds a good hand, game is highly unlikely unless in addition to his/her good hand, he/she holds a fit for the balancing partner's suit.

E. BALANCING JUMP OVERCALLS: ‑ Weak jump overcalls designed to consume enemy

bidding space are no longer needed, since one could simply pass to accomplish this same objective. Thus, a balancing jump-overcall should show usually a one‑suited hand, with at least a 6‑card suit, and the approximate strength of a sound opening bid.

Example:

1H P P ??? AKJXXX XX AXX KX (2S)

- 19 -

F. BALANCTNG NO TRUMPS: ‑ The requirements for a balancing no trump bid differ from a

direct no trump overcall as do all other balancing bids. A balancing no trump bid should have the following conditions:

1. 8‑10 HCP's (or more) (Subject to a Flexible Partnership Understanding)

2. A balanced or semi‑balanced distribution (Two doubletons allowed)

3. Usually a stopper in the enemy's bid suit, but not guaranteed

4. denial of distributional requirements for a good take‑out double

1D P P ??? (a) KX QIOX Q10M QXXX (1NT)

(b) AX AQX XXXX KXXX (1NT)

G. BALANCING CUE‑BIDS: ‑ Shows a highly distributional hand, usually 2‑suited. The

strength shown is somewhat ambiguous and may vary. The cue‑bidder may hold a strong offensive hand unsuitable for a take‑out double; or a weak distributional hand that has little or no defensive values and thus cannot stand to have partner pass a take‑out double should partner have “trap‑passed”. Examples: 1C P P ???

(a) KQJXXX AQJXX ‑ KX ("2C") (b) QXXXX JXXXXX X X ("2C")

H. PASSING IN THE BALANCING CHAIR: ‑ There are only two (2) reasons one should pass in the balancing chair. They include:

1. You have both length and strength in the enemy suit, making it most unlikely that partner has trap-passed. Thus, permitting your opponents to play the contract that has been passed around to you might well result in your side's optimum score on that deal.

2. You have such a weak hand, that any bid you might make is likely to produce an unmakeable contact, even in the unlikely possibility of finding partner with a reasonable strength. The hand probably belongs to the enemy anyhow, and, if partner had trap‑passed, the opponents are likely to have a much better contract than the one they are forced to play should you have passed.

Examples: 1H P P ??? (a) XX AJIOXX QJX JXX (Pass) (#l‑above)

(b) QXX JXX XXXX QXX (Pass) (#2‑above)

I. SUMMATION: ‑ Infrequently, and usually against inexperienced or poor bidders, balancing

will infrequently allow your opponents to bid and make game er achieve a better part‑score either of which they might never have reached if balancing had not occurred. On still other infrequent occasions one may get doubled and go for a considerable set because partner does not hold the necessary values that the auction suggests, or your side does not have a good fit despite your opponent's fit. ACCEPT THESE LOSSES. They will be rare and they will be more than compensated by the points earned by balancing. The use of balancing bids should, in general, be a source of considerable profit and gratification.

LESSON 9

INFERENCES AND DECUCTIONS

A deduction is a conclusion based upon known fact. For example, when a defender

shows out in a suit, declarer can count the holding in that suit in the hand of the partner who

exhibits the void. An inference is a conclusion based upon an assumed fact. For example, when an opponent passes his partner's opening one bid, you can infer that he/she has fewer than 6 HCP's.

Inferences and deductions about the opponents' high cards and distribution can both be made from the auction and the play of the hand.

A. INFERENCES FROM THE AUCTION:

1. A player who has passed the opportunity of opening the bidding in first or second positions cannot have 13 HCP's, for, indeed, all 13 HCP hands satisfy the Rule of 20 and would have opened the bidding Therefore, if such a passed hand has already evidenced 2 Aces and

1 King, in the play of the hand, he/she cannot hold a missing King or Queen.

2. A player who passes in response to his/her partner's opening hand cannot have 6 HCP's. If

he/she has, in the play of the hand, already evidence a King and a Jack, he/she cannot have

a Queen for which you might like to finesse against.

3. An opening 1NT bidder has the HCP's defined by his opening no trump stipulated

range, usually 15-17 HCP’s.

4. A responder who has bid 1NT in response to his/her partner’s opening one Heart, holds 6‑10 HCP's, no 4‑card Spade Major holding, and lacks primary support for his/her partner's Heart suit.

5. A 1NT (2NT) opening bidder who responds "2D" ("3D") to his partner's "2C" ("3C") Conventional Stayman bid lacks a 4‑card suit in either Major suit.

6. The partner of an opening 1 NT bidder who receives a 2S bid from his/her partner in response to a "2C" Stayman conventional bid, and who then bids 3NT had a 4‑card Heart suit, otherwise he/she would have never sought a Major suit fit.

7. A responder who has bid a new suit at the 1‑level has at least 6 HCP's.

8. A responder who has bid a new suit at the 2‑level has at least 10 HCP's.

9. An player who makes an overcall has at least 5‑cards in his/her bid suit, in addition to 8 or more HCP's at the l-level, and 10 or more HCP's at the 2‑level.

10 An opening no trump bidder does not have a singleton, a void, a 5-card Major suit holding,

nor a 6‑card suit.

- 21 -

11 A responder who raises a Minor does not have a 4‑card Major suit holding.

12 A opening weak two‑bid probably evidences a 6‑card suit, and a three‑bid a 7‑card suit.

13 An opening bidder of 1H or 1S has at least a 5‑card or longer Major suit holding.

14 If the opponents have opened and raised a Major suit and you have 5 cards in that suit, your partner has a void in that suit.

15. A responder who responds 1S to a 1C or 1D opening bid by partner does not likely have a 4-card Heart suit.

16. An opening bid of 1C or 1D probably denies a 5-card Major suit holding.

B. INFERENCES FROM THE PLAY:

1. If the opening leader against a no trump contract leads a deuce, then he/she does not have a 5‑card suit, since he has, by partnership and conventional understanding, led fourth from his/her longest suit.

2. lf the opening leader leads a low card, he/she does not have an honor sequence in that suit, again, by partnership and conventional understanding.

3. If the opening leader leads a low card, he/she either has a singleton, or else three, or more cards in that suit headed by an honor.

4. If, as declarer, you are missing the ace and the king in any suit, and the opening leader does not lead that suit, he/she does not have both the ace and king.

5. If the partner of the opening leader has bid a suit and the opening leader does not lead the suit bid by his/her partner, he/she probably has a good reason for not doing so. The most common reasons are: (a) that he/she has an honor sequence in some other suit that appears more likely to be fruitful (apparent from the opening lead), (b) that he/she has the ace of the bid suit or (c) he/she is void in that suit, or (d) does not listen to the bidding and/or wants to frustrate his/her partner.

Realize that the abundance of information available about high cards and distribution of the opponents' hands is voluminous. Additional inferences may be based upon attitude (low card = a "discouragement" or high card = a "come-on encouragement"), distributional signals like (High‑Low = an "even" or Low‑High = an "odd" number of cards in the signalled suit), the lead of low from an honor, the lead of top of a presumed sequence, and/or the line of play. Counting, deductive reasoning, and assumed inferences are all important tools towards better bridge and a confident, assured, and productive defense by the opponents; or a more successful offense by declarer.

LESSON 10

THE STAYMAN CONVENTION

A. DEFINITION: ‑ The Stayman Convention is used by the partner of a 1NT or 2NT opening

bid in order to seek the possibility of a 4‑card Major suit fit. When used in combination with Jacoby transfer bids it becomes a very useful tool in one's bidding arsenal. It is initiated and invoked by the responder and partner of the opening NT bid by utilizing an artificial “2D” forcing call. Stayman should not be invoked unless responder has at least an invitational strength hand; i.e., 9-10 HCP's or more. (Exception: Any hand where responder to the opening NT bid anticipates passing any feasible response by opener Example: XXXX XXXX XXXX X

Examples: 1NT P “2C” (or) 2NT P “3C”

B. BIDS AND RESPONSES PLAYING NON‑FORCING STAYMAN:

“2D”/2H/2S “5NT” maximum of 16‑17 HCP's else opener bids 6NT.

C. OTHER RESPONSES WHEN PIAYING NON‑FORCING STAYMAN:

1NT 3C/3D INVITATIONAL ‑ Shows a 6‑card suit headed by

two of the top three honors. Partner will proceed

to game if he/she holds the missing honor in the

Minor suit bid and stoppers in the other three suits,

else passes.

1NT “4C” FORCING ‑ The Gerber Convention asking for

Aces.

1NT 3H/3S FORCING ‑ A 5‑card suit forcing to 4H/4S/3NT

1NT 4H/4S SIGN‑OFF ‑ A 6‑card or longer suit with game

values.

1NT 2NT INVITATIONAL to 3NT. Opener passes with 15

HCP’s, else 3NT with 16-17 HCP’s.

1NT 3NT SIGN‑OFF

1NT 4NT FORCING ‑ (Not Blackwood) ‑ Is a quantitative

bid asking opener to pass with 15 HCP's and to bid

6NT with 16‑17 HCP’s.

LESSON 11

THE LEBENSOHL CONVENTION

A. PROBLEM: ‑ Suppose the bidding has gone.

Partner RHO You You hold either: (a) XX XX KJ10XXX XXX

1NT 2H ??? Or (b) AJX XX AQ10XXX XX

In (a) you would wish to bid 3D as a sign‑off; in (b) you would wish to bid 3D to push towards either 3NT or else 5D. Obviously you cannot bid 3D with both (a) and (b) while, at the same time, having partner being capable of discerning the difference between the two types on circumstances.

Often an overcall by the opponents over your partner’s opening 1NT will prevent you from making the response you would have otherwise made in a non‑competitive auction; i.e., one without interference. For example, one may be precluded from bidding Stayman (“2C”) due to the intervening overcall, and yet you might otherwise be interested in opener's Major suit holdings. Even natural bids, jumps, and NT raises become ambiguous after an overcall to partner's 1NT bid.

Obviously, several questions arise after such an overcall over your sides 1NT opening bid. Which bids by you are forcing and which are not? Which bids are invitational? Which bids are natural and which artificial? How do you bid Stayman and how do you affirm or deny a stopper in the enemy suit if you are seeking a NT final contract?

All of these questions and ambiguities are handled by the Lebensohl Convention.

B. THE LEBENSOHL CONVENTION: ‑

(a) A double is for penalties (NOT NEGATIVE)

Examples: 1NT 2S DBL. 1NT 2C DBL. 1NT 3H DBL.

(b) ANY 2‑level suit bid is natural and a sign‑off

Examples: 1NT 2D 2H 1NT 2C 2S 1NT 2H 2S

Examples: (lNT 2H 3C) (1NT 2S 3H) (lNT 2C 3D) (lNT 2D 3S)

- 25 -

(d) An ARTFICIAL “2NT” response is forcing and demands opener to puppet “3C”.

Responder can pass if he has a weak hand in Clubs, or he can rebid as follows: If he bids a suit

below the rank of the suit of the overcall, it is a sign‑off; if he/she bids a suit above the rank of the

enemy suit, it is invitational. In either last case scenarios, responder has at least a 5‑card suit.

Examples: 1NT 2H “2NT” P

“3C” P P (A weak hand in Clubs))

1NT 2H “2NT” P

“3C” P 3D (Sign‑off)

1NT 2S “2NT” P

“3C” P 3H (Sign-off)

1NT 2D “2NT” P

“3C” P 3H/3S (Invitational)

(e) A 3NT response achieved via:

(1) A direct jump to 3NT over an enemy overcall shows the values for game, but denies a stopper in the opponent's suit.

(2) "2NT" followed by a 3NT over partner's puppet “3C” bid shows value for game, plus a stopper in the opponent's suit.

(f) Stayman Convention is achieved in either of the following 2 ways:

(1) A Direct cue‑bid of the opponent's overcall suit is Stayman without a stopper in the enemy’s bid suit. It is forcing to game unless the partnership fails to find a Major suit fit and additionally lacks a stopper for 3NT. In that rare case, opener bids 4 of his better Minor suit.

(2) A “2NT” response followed by a cue‑bid of the opponent's suit over partner's forced “3C” is also Stayman, but this time with a promised stopper in the enemy suit. Lacking a Major fit, a contract of 3NT is finalized.

C. THE DISADVANTAGE OF THE LEBENSOHL CONVENTION: ‑ The machinery of the Lebensohl convention makes it easy to avoid a NT contract when neither side has a stopper in the enemy suit. Yet it in no way hinders the search for Major suit fits. In addition, it clearly defines which responses are non‑forcing, and which are invitational or forcing. To gain all this the only thing you give up is the natural meaning of the 2NT bid by responder; i.e., it precludes the ability of responder to the 1NT opening bidder to invite to 3NT by responding 2NT. In this situation, when playing Lebensohl and, therefore, without the ability to invite, it is best to go directly to 3NT when holding invitational values.

Example: 1NT 2S “2NT” P (AQX KXX JXXX XXX)

“3C” P 3NT (Showing a Spade Stopper)

(or)

1NT 2S 3NT (XXX AQX KJXX XXX)

Showing game values with NO Spade Stopper)

LESSON 11

THE LEBENSOHL CONVENTION

(Continued)

Note: In the above-referenced use of The Lebensohl Convention, Responder is responding with partner having evidenced 15-17 HCP’s with a subsequent interference. An almost exact circumstance evolves, with the only exception being that the order of the events taking place are reversed, occurs as follows: West’s partner has doubled in the direct position subsequent to a pre-emptive interfering opening weak 2-Bid.

Example: 2(B)

??? Dbl. (Take-out)

All of the same meanings become available to this responding partner, responding to a strong Take-out Double by partner, subsequent to a weak-2 opening pre-emptive bid by the opponent.

Examples: 2B

a. (Pass = Penalties) ??? Dbl. (Take-out)

---------------------------------------------------------------------------------

b. (2H = To Play) ??? Dbl. (Take-out)

--------------------------------------------------------

c. (3S = Game Force) ??? Dbl. (Take-out)

(with 5 Spades)

--------------------------------------------------------

d. (3H = Stayman Game) ??? Dbl. (Take-out)

(Force with 4 Spades)

--------------------------------------------------------

e. (2NT = Forces 3C) ??? Dbl. (Take-out)

--------------------------------------------------------

There are, therefore, two instances, of almost identical circumstances, for Lebensohl usage.

THE LEBENSOHL CONVENTION

(Continued)

Modification Of Lebensohl Subsequent To A “2C” Overcall By Responder’s RHO

Normally, the methodology of bidding Stayman, with a stopper in the overcall suit bid by Responder’s RHO, is to puppet through 2NT and then for Responder to bid the same suit as the overcaller, as seen in the Example to follow:

1NT/”3C”

P/ 2S/P

“2NT”/”3S” (Game Force - Stayman for Hearts but

with a Spade Stopper)

Note, however, that this technique is stifled when the overcall suit is Clubs.

1NT/”3C”

P/ 2C/P

“2NT”/”4C” (Game Force - Stayman with a Club Stopper

but in this instance the partnership is already past 3NT should responder not find opener with a 4-card matching Major suit.)

In this specific singular instance, therefore, the partnership using Lebensohl must have ready the following deviation from the norm so as to specifically cope with a Stayman attempt, game forcing bid with a Club stopper by Responder. In this instance the bidding must proceed as follows:

1NT/”3C”

P/ 2C/P

“2NT”/”3D” (Game Force - Stayman with a Club

Stopper (Not an invitational try in

Diamonds)

LESSON 12

RESPONDING OVER PARTNER’S 1NT OPENING SUBSEQUENT TO THE OPPONENT’S

TAKE-OUT DOUBLE

A. CIRCUMSTANCE: ‑ Your partner has opened the bidding with 1NT (15‑17 HCP's). Your right‑hand opponent (RHO) has overcalled with a "Take‑out Double" evidencing an equivalent or better hand. How do you offer a response and under what circumstances? When is it desirable to act and when is it not? Which bids are natural and which are artificial? Are transfers still in effect; and lastly, how do you invoke the Stayman Convention looking for a 4‑card Major suit fit if you desire to do so, while at the same time being able to bid Clubs as a natural alternative bid?

Partner has shown (on average) 16 HCP's as has the opponent's overcall which evidences an equivalent or better holding. Thus, the combination of opener plus your RHO is equivalent to approximately 32 HCP's leaving, at most, 8 HCP's available between you and your left‑hand opponent (LHO), the partner to the doubler. Therefore, it is possible, but surely highly unlikely, in all but the most unusually distributed scenarios, that game is possible with your team's combined, at most, 24 HCP's.

The responder must also realize that if he/she does not have the majority of the missing approximate 8 HCP's, then the Doubler's partner does, and Doubler's responder is likely to pass the Take-out Double thereby converting it to a penalty scenario. Responder to the opening 1NT must, therefore, assume a posture that the less he/she has, the more he/she must attempt to save the opener from a probable impending disaster by steering the bidding to any 5‑card suit if it is available. Otherwise he/she must pass. That's the way the cookie crumbles!!!!

B. RESPONSES:

(1) ‑ All of the reason's that validate the worthiness for both the Stayman Convention and Transfer scenarios are still fully valid not‑with‑standing the intervening Take‑out Double. Therefore, most players play what is called "FRONT OF CARD" understandings; namely, that:

(a) “2C” = Stayman asking for a 4‑card Major suit.

(b) "2D" = A transfer to Hearts

(d) "2S" = A request for a Minor suit preference; namely, a rebid by opener of 3C if his/her Club suit is equal or longer that his/her Diamonds, or "2NT" if opener's Diamonds are longer than his/her Clubs. This third leg of a 3‑way transfer scenario is called "MINOR SUIT STAYMEN".

(e) "2NT" = An unlikely bid, since (1) the 1NT is already doubled, and (2) not enough HCP's exist for an invitation to game and is thus highly unlikely anyway.

- 27 -

(2) Suppose, however, that the responder wishes to play the contract in 2C or 2D. He/she cannot bid 2C to play at 2C (for it will be rightfully construed by opener as Stayman), and cannot bid 2D to play at 2D (for it will be rightfully construed by opener as a transfer to Hearts). Not to worry !!!!!

(a) Responder simply says "REDOUBLE". This is a conventional response which, in this

particular singular scenario of: (1NT Dbl. ReDbl.) requests of opener to "puppet “2C” which can be either passed by responder if Clubs were the intended destination, or else responder will correct to 2D which must be passed by opener. Under no circumstances is this "Redouble" for added bonus points.

Examples: XX XXX XX AXXXXX 1NT Dbl. "ReDbl." P

“2C” P P

XX KX XXXXXXX XX 1NT Dbl. "ReDbl." P

“2C” P 2D

(3) Suppose, however, that most, or all, of the missing 8‑10 HCP's are held within the hand of the partner to the opening 1NT bid, especially if his/her hand is balanced absent a predominance of any particular suit. In that scenario, the responder may elect to simply "PASS", awaiting the required mandated desperation bid of the Doubler's partner. The opening 1NT bidder will naturally pass, allowing the responder to the opening bid of 1NT to "Double" whatever bid player #4 makes in order not to let the doubled 1NT contract to stand.

Example: INT Dbl. P 2B Note: In such instance it is usually best for

P P Dbl. the defense to continue to lead trumps

whenever possible in order to eliminate them from play thereby converting the play of the hand back to NT where the defenses high card

domination will most likely prevail.

Alternatively, if all the points are held within player #4's hand, player #4 may pass trapping the 1NT bidder into a Doubled 1NT non‑makeable contract, especially since 15‑17 HCP's are located behind the opening 1NT bidder, diminishing his values while, at the same time, enhancing the value of the 15‑17 HCP's in the hand of the Doubler who sits behind the opener's 1NT position.

Example: lNT Dbl. P P

In such instances, since the partner of the opener took no defensive action (obviously devoid of any 5‑card suit to go along with his 0‑1 HCP's), the opener is oft times better to bid his/her 5‑card Minor suit if it be present. within his/her 1NT distribution. If not, watch the slaughter.

LESSON 13

PRE-EMPTIVE BIDDING

“SUIT QUALITY TEST” AND “THE RULE OF 2*3*4”

Many duplicate players pre‑empt the bidding with a weak 2‑, 3‑, 4‑, or 5‑level bid with the enthusiasm of a suicidal maniac playing a game of Russian Roulette, oft times with a pistol loaded only with "blanks". For the duplicate player, "blank cylinders" represent probable zeros on the score recap sheet totals; and their use denies added enjoyment to the game for both the user and his/her partner, while enriching the opposition.

Accordingly, it is with a degree of appropriateness that definitive methods of some fashion

and logic must be employed so as to determine which suits are appropriate for a weak pre‑emptive

bid, and what level should be considered as a reasonable one to place the pre‑emptive call.

Obviously, vulnerability, sizing‑up of the opponents, fortitude or lack thereof, whether partner

has previously passed or not, position at the table, outside Major suit holdings, and many other

factors have some relevance in this matter; but in general, two methods are suggested as the

main considerations which should guide one's decision in this matter They are: (1) suit quality, and (2) The Rule of 2‑3‑4. If these two guiding factors offer a variant preference, one should perhaps consider some
