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.

(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.
