Matchpoint (Pairs) Strategy at Duplicate

Bridge

The Bidding :

Bid aggressively. Duplicate pairs tend to bid "close" games

and slams, so don't settle for a safe partscore if you think

there's a fair chance (60 percent or better) that you can

make game.

Choose the highest-scoring game. For game contracts,

you should be most anxious to play 4H or 4S, willing to play

3NT and reluctant to play 5C or 5D. If you have game

values and a club or diamond fit, consider playing 3NT

instead.

Choose the safest partscore. When you have minimum

high-card strength, choose the safety of a trump suit. A

major-suit is still best, but if you're deciding between a

notrump and a minor-suit partscore, play the suit

contract if you have a fit.

Overcall freely. At the one-level, don't be afraid to make

light, lead-directing overcalls (as few as 8 or 9 points if

you have a good suit), especially if you're not vulnerable

and your opponent opens a minor. If you have to go to the

two-level to bid your suit, though, be cautious. For a two-

level overcall, you should have good high-card strength

(11-12+ pts.) and a very good suit (a strong 5-carder or,

better, a 6+-card suit). A vulnerable two-level overcall

should be even stronger.

Raise partner's suit freely. Even if you're light in high-

card points, stretch to raise partner if you have a fit for

his suit, especially in competitive auctions.

Sacrifice more often. If you have a good fit, sacrifice

freely if your opponents are vulnerable and you are not.

But be very conservative about sacrificing when you're

vulnerable.

Don't "sell out" too low. If the opponents stop at a low

level, you don't have to have a strong hand to balance back

into the auction. The best situations for competing are

when:

(1) You're not vulnerable;

(2) The opponents have stopped in 1 or 2 of a suit

contract (not 1NT or 2NT); and

(3) You hold shortness in the opponents' trump suit.

Double more partscores. If you bid to a partscore you

think you could have made, but your opponents bid over it,

a double is sometimes necessary for you to get even an

average score. (Be very careful in choosing when to use

this tip!)

Use a simplified form of the "Law of Total Tricks (Trumps)"

for competitive decisions. In partscore situations --

those where you've found a fit but wanted to stop below

game -- don't let the opponents push you to the three-

level unless you have at least a 9-card trump fit.

The Play:

Make "normal" opening leads. Don't try for a "top" by

choosing an unusual lead. Against most contracts, choose

a safe, non-deceptive opening lead.

Look for overtricks. Unlike in rubber bridge, it's

sometimes right to make a fairly risky play trying for the

overtrick -- especially when you're in a "normal" contract

that you think will be bid by other pairs.

Play it safe if you're in an unusual contract. Go for the

sure plus score if you're playing or defending a contract

that you think probably won't be bid at most tables.

In General :

Play with the "field". When in doubt about what to bid or

play, try to guess what might be happening at other tables

and go for a similar result.

Consider using 15-17 points as the range for your opening

1NT bids. A 1NT opening often gives you a bidding

advantage because your responses are so well defined and

your opponents will find it more difficult to enter your

auction. Most duplicate players use the 15-17 range

(rather than 16-18) because it allows them to open more

hands with 1NT. If you use this range, responder will need

to adjust his point requirements up by 1 pointt. You should

also change your 2NT opening range to 20-21 or 20-22

points.

Consider adding popular conventions to your system.

Because many duplicate pairs play the conventions and

treatments listed below, you might want to try them, too.
