The following happened to me recently while playing on bbo. I am declarer as north. The contract had two tricks left to play. I lead from the board and while east is deciding what to do, west (LHO) claims!! Only trouble is he doesn't have both tricks. He will win the one that I have led from the board, but his remaining card is one that I can beat in my hand. His partner does have one higher than mine also in that suit but he has to discard first and if he discards this card, then his partner's claim is invalid. I have played the hand to intentionally "squeeze" west and he pauses to think and does not play a card before east claims. Clearly RHO/west is not sure which to discard. I deny claim but now RHO can now infer what to discard, and the hand proceeds and they get the last two tricks. I commented to the table that it was inappropriate for east to have claimed and he, an expert, responded with a tongue lashing saying that it was obvious to his partner what card to discard blah, blah, blah and that I didn't have to be a rocket scientist to figure that out.? The only problem was his partner clearly didn't know which to discard as evidenced by his lengthy pause during the play. I could see that a savvy defender can do this intentionally to pass info. to his partner and appear to have just made an honest mistake. I wrote this situation to bridge base online and asked both if this situation was unethical and also why does bridge base allow a defender to claim remaining tricks out of turn? I got back a tersely written agreement that this was not fair and a recommendation for me to bring it up here in the forums and nothing more, suggesting they had no intention of changing to claiming in turn only. So I put it out there. Anyone think defense should only be allowed to claim in turn? I would really appreciate responses either way. If there is a rationale for leaving things the way they are, I would appreciate knowing what it is also . For reference the hand was xxxxxxxxxxxxxxxxx Thanks, timouthy
