BEGINNER S BRIDGE
LESSON 7
OVERCALLS AND RESPONSES
Competitive bidding between opponents is all
part of the game of bridge. This interchange
of information between the partnerships may consume levels of bidding otherwise
needed by the opponents and, thus, their subsequent action. There are both advantages and disadvantages
to competitive bidding. They include:
Advantages
of Competitive Bidding
1.
Despite
the opponents having opened, your partnership may have the predominant point
count and enough combined strength within the partnership to make a part score,
or even a game.
2.
Even
if your side doesn't have the strength for game, you still may be able to
interfere with your opponent's exchange of information thus making it difficult
or even impossible for them to arrive at their best contract.
3.
If
your opponents do play the contract, the information imparted from your
competitive bidding may
assist your side in defense including
the best opening lead.
Disadvantages
of Competitive Bidding
1.
If
you are bidding singularly to interfere with the opponents, and inadvertently
bidding beyond your sides capacity, you might end up playing a contract you
cannot possibly make.
2.
At
the same time you are giving your partner information about your hand, you are
also giving information to you opponents as well, thereby assisting them in
making their specified contract.
THE
OVERCALL ‑ This is the simplest form of a competitive
auction. It occurs subsequent to the
opponents opening the
bidding. It can be made at the l‑level,
the 2‑level, or even
higher. It can be made in a suit or in No Trump.
Requirements For a Suit Bid
1. A 5‑Card or longer
suit (Regardless of Major or Minor Suit)
2. 8+ HCP's or more at the 1‑level
and 10+ HCP's or more at the
2‑level
3. A "suit quality" that approximates the bid
contemplated.
4. An increased quality of suit and/or points if vulnerable.
5. If a choice of suits to
overcall is present bid the
higher‑ranking
first
Requirements For 1NT Overcall
1. 15‑17
HCP's (That is Equivalent to a 1NT opening hand)
2. An Evenly Balanced Hand (No Voids, Singletons, & at
most l
Doubleton)
3. At least one STOPPER in the opponent's bid suit;
i.e.,
strength &/or length in the suit bid by opener.
RESPONDING TO AN OVERCALL ‑
When the overcall is made in a suit, and since the overcaller promises
at least a 5‑card suit, the responder to the overcaller needs only 3‑card
support in order to raise. If the
overcall is a 1NT overcall, and is effectively the same as an opening 1NT with
the added feature of a guaranteed stopper in the opponent's suit, and the
responses here are the same as to a l NT opening bid.
