Hand Evaluation - The Default

PITBULLS:

D.S.I.P. theory is a balancing act with forcing pass theory. There are many auctions that the bidding does not reveal that you own the auction however you may. In all these situations , we still must revert to our default so assume we do not own the auction. Our default is D.S.I.P. theory. Pre-empts by partner are a well known exception to D.S.I.P. theory.

The auction went 1♠-3♠-4♠-? With the 3♠ bidder being vulnerable but the opponents not . Do we own the auction ? Are the opponents bidding 4♠ to sacrifice or to make ? The answer is we simply do not know. If we interpret the 3♠ bid to be a pre-empt due to the long suit , penalty doubles should apply. This pre-emptive vul bid usually defines the meaning of partners double to be penalty . If we interpret the 3♠ bid as an unknown overcall , D.S.I.P. theory applies.

Since it is rare that the 3♠ jump is done on a “rock” hand , I feel for the sake of D.S.I.P. theory , we should consider the bid as a good solid “pre-empt” . Penalty doubles by partner should apply rather than D.S.I.P. doubles. BJ held ♠QJ10x ♥Kxxx ♦x ♣Kxxx so has an easy 4NT bid if he wanted me to bid my minor. BJ doubled 4♠ for penalty so that should end this auction.

I find it is easier to learn forcing pass rules which is the way Eric Kokish interprets his “two way doubles”. It is much better to figure out when Forcing Pass Theory is applicable or the rare cases where the penalty double is allowed ( opposite a pre-empt ) than trying to figure out if D.S.I.P. theory applies. D.S.I.P. theory is just the default when a penalty double & forcing pass theory do not apply.

As my partners have expressed it , we need triggers that determine the meaning of penalty doubles. I think it is easier to go this route. Figure out if & when forcing pass/penalty doubles apply so default to D.S.I.P. in all the other cases. We allow penalty doubles when we are no longer competing or after we have already made a D.S.I.P. double. If we know our rare penalty double situations & know forcing pass theory , D.S.I.P. theory situations are just what is left over.
