Matchpoints; lead ♦J; Table Result 6♥?
I was called a second time as TD to SB's table in the "Bunnies in Need" charity SIM on Tuesday, and on this board had to decide whether to force declarer to play in strict accordance with his claim statement. SB, West, led the J♦ against the reasonable slam and HH, South, tried the queen but East, ChCh, played the king, won with South's ace. After a little thought, HH led a heart to the queen and East's jack. Pleased to have got that right, HH claimed, and stated. "I will return to hand with a top spade and play a heart to the ten on the second round of trumps. If you have Grosvenor'd me, ChCh, you can have your little chuckle."
SB swooped. "Then I will play the king of hearts on the second round", he gloated. "And you are obliged to play the ten, in accordance with your claim statement of how you intended to make 12 tricks and the order in which you intended to play the cards. I think we can enter -100, can't we, or do we need to waste the TD's time again?"
How do you rule?
