Hand Evaluation - Forcing Pass Auctions
In order to play D.S.I.P. doubles effectively , you must know when they do not apply so forcing pass theory takes over. O.K. we will assume you know the understandings involved in forcing pass theory but lets examine the auctions which “turn on” forcing pass theory. There is also a “when” factor with forcing pass theory. Sometimes forcing pass theory does not “kick in” until you bid game with the opponents bidding again. Otherwise , forcing pass theory is in effect immediately.
Essentially forcing pass theory applies when it is clear that you own the hand. You must have your ear to the bidding so finely tuned to pick up the auctions that forcing pass theory applies . The obvious auctions that turn on forcing passes are when your partnership opens a
· When your side has overcalled at the two level & partner has responded in a new suit . You own the hand so forcing passes apply after you bid game .
Lets discuss a couple with examples submitted by Stan Cabay . A 2/1 in competition is forcing only one round if the suit rebid but if you continue on to game , Forcing Pass Theory kicks in as your 2/1 shows a reasonable hand.
