- SIMPLE OVERCALLS
-
-
- The partner of an overcaller ("advancer") will picture him as
- having a good long suit in a hand which may not qualify for an
- opening bid. It is best not to stray too far from this picture.
- Advancer will assume that overcaller has at least one defensive
- trick when not vulnerable, two when vulnerable. With less defense
- it is usually better to pass or preempt rather than make a simple
- overcall.
-
- The hand should not be too strong, either. Even though good players
- raise overcalls with light support, a game may be missed if the
- simple overcall is based on a very strong hand. Strong hands are
- better shown by takeout doubles, jump overcalls, or cue bids. Do
- not, however, make an off-shape takeout double just because the
- hand is rather strong for an overcall. See chapter TAKEOUT DOUBLES
- in the book "Conventional Doubles" for a discussion of the
- requirements for a takeout double.
-
- Overcalls in a weak five-card suit or a four-card suit are seldom
- advisable. Both should occur at the one level only, and the four
- card variety should have three of the top four honors to make up
- for the shorter length.
-
- Overcalls at the one level require a minimum of three to five
- playing tricks, depending on the vulnerability. A hand with only
- three playing tricks may be bid only with favorable vulnerability,
- a good suit, and good distribution:. S-AQ1087 H-3 D-9873 C-542.
- With unfavorable vulnerability, a hand with the minimum of five
- playing tricks should also include a good suit. Otherwise it is
- best to have extra playing strength.
-
- Be even more conservative when coming in between two bidders,
- unless the vulnerability is favorable.
-
- With a good defensive hand, do not overcall without extra playing
- strength. Then, if partner makes what he thinks is a sacrifice bid
- in your suit, you may make the contract. Prefer a pass, takeout
- double, or notrump bid with a good hand that lacks playing
- strength. Overcalls that are minimum in regard to playing strength
- should be defensively weak also. Otherwise you will be going down
- when the opponents can make nothing their way.
-
- The preemptive value of the overcall is an important consideration.
- Stretch to bid 2C over 1D, but not 2C over 1S. The 1S overcall of
- 1C is often very weak, but there is little justification for making
- an overcall of, say, 1H over 1D. Partner should take this factor
- into account in her bidding.
-
- Suppose you have S-AQ743 H-K106 D-43 C-K86, vulnerable. Pass over
- a 1H opening. You might double 1D. Over 1C you can bid 1S because
- of the preemptive effect of skipping so many ranks. After passing
- hands like this, you can back into the bidding later if the auction
- stops at a low level. Should the bidding get too high for a back-
- in bid, partner will probably be broke anyway. Often you will gain
- a trick in defense when declarer cannot place the outstanding high
- cards or distribution.
-
- Lead direction is also important. With a borderline overcall, pass
- if the suit you must bid is not a good one for lead direction--
- especially if partner is likely to be on lead.
-
- It is possible to make a takeout double after overcalling. See
- chapter TAKEOUT DOUBLES in the book "Conventional Doubles."
