Drury (2-WaY Reverse Drury)

 

You should open light in 3rd seat in a good major suit but not in a minor.  The reasons are:

 

Major Suit Openers. An opening 1© or 1ª is preemptive to 4th seat.

 

Consider: if your partner (the dealer) and 2nd seat didn’t open and you have relatively few points, where are they?  4th seat, of course, so make it harder for her to bid. Not vulnerable, as little as 8 points is OK as 3rd seat opener in with at least ªAQ986.

 

Minor Suit Opener.  If you open a weak minor-suited hand, you make it easy for 4th seat to overcall in a major suit, even with modest values and thus get into the bidding cheaply.

 

If you play weak major openings in 3rd seat, you must also play Drury, a convention for the dealer, who passed.  It’s on if 4th hand passes or doubles, otherwise it’s normally off, but see Variations below.

 

Reverse Drury responses by Dealer (a passed hand). 
A raise to 2
© or 2ª is normal, showing 6 to 9 points. [P – P – 1© – P  2© …]   
A 1NT bid is normal, is not forcing, and denies 3+ trumps.
[P – P – 1
© – P    1NT …]

 

The strongest hand dealer could have is a limit raise, showing 10 to 12 dummy points and 3 or more trumps.  But she doesn’t know if 3rd seat opened with 8 points or 18 points, so she can’t jump to 3 to show limit raise strength.  Instead, she should bid 2§, an alertable Reverse Drury call, showing a 10 to 12 dummy point limit raise. [P – P – 1© – P    2§* …] (The original Drury used the reverse of this rebid technique, thus the designation “Reverse Drury” as played today.)

 

Opener’s Rebids. If opener rebids her major suit at the 2-level, she has a weak hand, but is in a 8+ card fit at the 2-level - - safe.  If she rebids anything else, she has a real opening hand and the auction can go to game or whatever. 

 

Two-Way Reverse Drury is an improvement on Reverse Drury. A bid of 2§ shows 3 trumps but a bid of 2¨ shows 4 trumps, i.e., “Bad” and “Good” Limit Raises. Knowing about a 4th trump can be the difference between making 9 tricks or 10 tricks.


[P – P – 1ª – P     2¨* P – 4ª …]  A Two-Way Reverse Drury sequence, showing 4 trumps and a limit raise hand by dealer. Opener, with a real opener, goes on to game.

 

 

[P – P – 1© – P      2§* – P – 2© . . .]   A weak hand with 3 trumps

[P – P – 1© – P     2§* – P – 2¨ . . .]    A real opener with Diamonds

[P – P – 1© – P     2§* – P – 4©]        A game-going hand with a Limit Raise.

[P – P – 1
¨ – Dbl  1© – P – 2© . . .]    Drury is not applicable. (Minor opener)

[P – P – 1ª – 2§       2¨ – 3§ – P. . .]   A 3rd seat opener and a 4th seat call.

Drury is (normally) off, so the 2¨ is real, and denies 3+ Spades because it's not forcing (by a passed hand).

 

VARIATIONS

It’s possible to play Drury is ON after 4th seat interference. Some variations:


A. If the Drury bid can be made over the interference, just make it:

[P – P – 1ª – 2§       2¨ . . .]  Shows a 4 trump Limit Raise; ignoring the 2§ bid.

[P – P – 1© – 1ª       2§ . . .]  Shows a 3 trump Limit Raise; ignoring the 1ª bid.    

[P – P – 1© – Dbl       2§ . . .]  Shows a 3 trump Limit Raise; ignoring the Dbl bid.

 

B. If the Drury bid can’t be made over the interfering bid, Double can be used to show a Limit Raise, instead of the presumed Negative Double.

[P – P – 1ª – 2©     Dbl . . .]  Shows a 3 or 4 trump Limit Raise over the 2© bid.
                                             As this is normally a Negative Double, it’s
                                             alertable.  

 

C. If the interfering bid is the one the Drury bidder wanted to make, a Double can be used as a “Stolen Bid”:   

[P – P – 1© – 2¨     Dbl . . .]  Shows a 4 trump Limit Raise.   

[P – P – 1ª – 2§     Dbl . . .]  Shows a 3 trump Limit Raise.   

 

All three variations can be used together, and collectively, they comprise a considerable improvement over the “Drury is off after interference” approach.
