ACBL. Club game. NS B pair v. EW C pair. Strata open/1500/750. As you have probably already guessed (otherwise there wouldnt be an issue), E hesitated prior to his pass. NS complained that W should not X as Es hesitation provided unauthorized information. With a dearth of B and C players, I added A players to those that I polled. One A player who played W and had passed as dealer said he wouldnt double: not knowing much about the quality of his partners third-seat opener, he had nothing else to say. The other A players said they would have opened the W hand with 1♣. They then said they absolutely would have doubled 4♥, two saying they were not about to let NS steal their contract for free.
Heres my concern. Law 16B.1.(b) defines a logical alternative action as being one that, among the class of players in question (my emphasis), would be given serious consideration by a significant portion of such players. What is still gnawing at me a bit is that the players I polled who said they would double 4♥ also said they would have opened the W hand with 1♣. If the law requires us to use as "the class of players" those who wouldnt open the W hand, should we therefore conclude those players are by their nature so conservative in their bidding they would pass 4♥ without the UI? Would all players who passed the W hand fail to double 4♥? The player in question was the only player I polled who passed as W who also said it was an easy double for him with two aces and his partner opening. Ws partner opened in the third seat, so Im not sure partner opening gives you much comfort - it could be 10 across from your 11. The preempt by N causes me to believe N doesnt have much of a hand, but S could have an opening hand - indeed perhaps as many as 16 HCP, as an unpassed overcaller. Certainly less since E opened, but W would know from his hand that S could still have 11-12. Is knowing your side has half the points or more enough to make you double a major suit game contract? With two aces and Ns preempt, Id be inclined to say probably. We may not have a game but they probably dont either.
Regardless, we let the table result of 4♥X off 2 stand. It was above average for EW. Three pairs found a ♣ or ♦ game, three played in a ♣ or ♦ partscore, one played in 4♥ not doubled off 2, and one EW knucklehead tried 3NT which went off 1 - not sure which one promised a ♥ stopper.
Let me know what you think.
