Hand Evaluation - Redoubles & Forcing Pass
No not forget that playing D.S.I.P. theory necessitates that you switch between two different modes of Bridge thinking. If you “own the auction” forcing pass theory applies & D.S.I.P. theory does not exist. Redoubles by responder or opener imply that you “own the hand” . Penalty doubles turn on forcing passes at any level. If you double 1NT or systemic bids like unusual NT , Michaels or other systemic toys you “turn on “ forcing pass theory , so trump stack penalty doubles come into play.
BJ Trelford has quite a hand that drives this point home . ♠AJ109xxx ♥J ♦KJ10x ♣x , I opened 1♥ & LHO doubled. BJ redoubled ! My RHO bids 2♦ , I doubled so all pass. When the smoke cleared , +1100 against NV opponents for our side. Hard as it was for BJ to believe , my double was penalty ! I held ♠x ♥AK10xx ♦Q98 ♣KJ10x , so I thought that defending was a good idea.
Maksymetz/Jacobs introduce a twist to forcing pass theory when partner doubles a conventional bid like unusual NT or Michaels. They call this concept the “double pass” . Even though penalty doubles should apply in these auctions , they revert to negative double theory or D.S.I.P. theory . They play the first double by opener as just showing a good hand suitable for defensive action. A bid of course would be an offensive hand that you planned to pull the penalty double anyway. A pass could be a trump stack penalty double in their system or just a minimum. The initial doubler must re-open with a double in all cases.
The advantages to their idea is that a penalty double is only going to occur if the openers hand is suitable defensively. If the original doubler has their suit , of course the double gets converted which I suspect if the most frequent action. If the opener has their suit , of course the double gets converted the other way.
The drawback ? to this system is the “single handed” trump stack double is impossible by the original doubler. If opener passes just with a minimum , the penalty double must be pulled as the doubler might not even have that suit. This is insurance against them making a doubled contract with light major suit openers. As usual, with these type of understandings you muss give away something to get something. They must feel this a safer way to play penalty doubles in these type of auctions.
♠AKxxx ♥Kx ♦xx ♣KJ109 1♠-2NT-X-3♣
P-P-P Partner’s hand is ♠xx ♥Axxxx ♦AKJx ♣xx
♠AKxxx ♥Kxx ♦Axx ♣xx 1♠-2NT-X-3♣
X-P-P-P Partner’s hand is ♠xx ♥Axxx ♦xxx ♣AKJx
There style is similar to how we play penalty doubles of 1NT with them escaping. The 1st double just shows cards so the pass is the penalty double. The penalty double responder must re-open with a double so the contract gets converted for penalty. This in effect is introducing D.S.I.P. concepts in a forcing pass auction.
