Forcing Pass - One over One Response

 

PITBULLS:

 

More on Forcing Passes from notes Eric Kokish sent me. One common thread with these articles is what happens when forcing pass theory does not apply. Kokish plays “transferable values” doubles or D.S.I.P. when forcing pass theory does not apply. In other words , forcing passes defines when D.S.I.P. doubles are applicable.

 

 

AFTER A ONE-OVER-ONE RESPONSE

 

(1)   Opener invites game and responder accepts. Forcing pass in effect.

(2)   Responder invites game and opener accepts. Forcing pass in effect.

(3)   Opener invites game and responder does not accept. No forcing pass.

(4)   Responder invites game and opener does not accept. No Forcing Pass.

(5)   A cue-bid by opener creates forcing pass.

(6)   Opener raises to game or jump raises to game after a weak jump overcall. Forcing passes are in

effect only by opener, VUL vs NONVUL (so says Kantar).

According to EOK:

The vulnerability does not matter; what is important is the NATURE OF THE RAISE. If it is

defined as HCP, passes are forcing; if it is defined as distributional and tightly limited, there

is no reason to treat a pass BY THAT HAND as forcing. Nor is there any reason to treat his

partner's pass as forcing since he can do the right thing facing a well-defined hand.

(7)   Opener makes a single raise and responder bids game. Forcing passes by the responder, VUL

vs NONVUL, or by either player if "sound of bidding" warrants such a notion. So says

Kantar.

According to EOK:

This is exactly the same case as: 1H-(1S)-2H-(2S); 4H.

Responder will usually have a distributional hand and is on his own and may make a

unilateral PENALTY DOUBLE or bid on, as he planned to do. Opener is invited to make a

PENALTY DOUBLE of his own but he is otherwise expected to PASS. There are no

FORCING PASSES. This is a variation of he SPECIAL CASE.

(8)   Opener's side voluntarily bids game with no established fit. All subsequent passes by both

partners are forcing.

(9)   If both sides have an established fit, and both sides bid game, and there have been no weak

jump overcalls, takeout, responsive or negative doubles, forcing passes are in effect when:

(a) VUL vs NONVUL (by the unlimited hand only);

(b) Opener leaped from one to four in partner's suit showing a big balanced hand;

(c) The "sound of the bidding" demands it (they are sacrificing);

(d) Your side clearly has the preponderance of high cards.

So says Kantar.

According to EOK:

(a) does not ring true. No one has shown the preponderance of high cards. Everyone may

be a trick or two beyond their depth and gambling slightly. Passes are NONFORCING but

DOUBLES show TRANSFERABLE VALUES and express an opinion about "ownership" of

the hand. ( D.S.I.P. BOB C )
