Matchpoints; Table scores: all different.
The TD was called three times at different points in the evening on this hand from a North London club last night, and, as a playing director, he recused himself from playing the hand. At many tables East had bid 4S at his first turn, but the three TD calls all featured an auction much as above, with one North bidding 2NT to show a mixed raise instead. All had a BIT by West as shown.
At table 1, East bid 4S which NS allowed to go undoubled, and declarer lost the obvious 4 tricks for a good score for EW. South called the TD claiming that 4S was based on UI, as East knew from the BIT that his partner did not have KQxxx Qx Qxx Jxx or the like, when 4S would go for 800. East claimed that he was always going to 4S, but did not want to jump before he was pushed, which is why he had not bid it on the previous round.
At table 2, East doubled, and West decided to defend. Declarer misguessed the queen of diamonds expecting East to have it for his double and went one off for a huge score to EW. South called the TD claiming that double was based on UI, as East knew from the BIT that his partner had extra values and he had an ace. The fifth trump was a particular reason not to double. East argued that they played double here as "do something sensible" and that his partner could still save if it was right.
At table 3, East passed, and again declarer misguessed the queen of diamonds expecting spades to be 6-4 for West's tank and East's pass. He also thought West would not be thinking with Qx(x) of diamonds. +100 was a good score for EW. Again South called the director claiming that Pass was based on UI, as East had a normal 4S at these colours, and that he passed because he thought partner had extra values and might well have been considering doubling 4H. South claimed the risk of 4S being a phantom had gone up because of the BIT, and that Pass should be disallowed.
How would you have ruled in all three cases?
