suit opening bid With a normal opening bid, opener rebids normally but with a light opening hand, he negatives with 2 With a distributional hand containing length in opener's major but with fewer than 9 HCP, responder preempts by jumping to the 3-level in opener's suit Reverse Drury A rebid of 2 shows a full opening. While not universally accepted, a bid of 2 by opener after opening 1 is also a weakish bid showing five spades and four hearts (or better). With a good hand (say 15 or more points) opener may simply jump to game (four of the major suit). Other bids tend to be natural and descriptive, in effect a game try. With an excellent hand, opener may be interested in a slam and will bid accordingly. Responses by the Drury bidder In the sequence 1M-2; 2, opener has confirmed a full opening hand and the following rebids by the Drury bidder enables opener to judge the best final contract: 2 - I have a minimum Drury hand 2 - I have a maximum Drury hand but only three trumps 2NT - I have a maximum Drury hand with four trumps Two-way Drury In this variant, the passed hand with 10+ points responds 2 to show exactly three-card support and 2 to show four-card support or better. This may help opener evaluate the probability of a successful game contract. Real club (or diamond) suit If the passed hand has 10+ points and a real club suit (or a diamond suit, when playing two-way Drury), this cannot be shown naturally at the two-level. One possibility is that a jump to 3 (or 3) shows this hand. An alternative is to use the forcing notrump. A third possibility (and the one recommended when the convention was introduced) is to bid 2, then rebid three of the minor. If this last approach is used, opener must be careful about jumping in own suit without extra length. Variation for four-card major systems The above examples are suitable for use with five-card major systems such as Standard American. Variations are required for use with four-card major systems such as Acol. See also Strong Notrump After Passing (SNAP) Notes Further reading Bridge conventions
