Table Result 4S? IMPs Opening Lead ♥T
SB caused more problems this week at the North London Club, where the facts are broadly as reported here. West led a top heart and declarer, SB, won with the ace (East playing the queen), drew trumps and played the nine of diamonds to the ten, queen and ace. East, the Chimp, a fine player, returned the jack of diamonds and SB won, crossed to a heart and played a diamond. West, RR, played the seven and East overtook with the eight. Now RR attempted to lead to the next trick, but did not expose a card before the Chimp butted in. "It is not your lead, partner; I overtook your seven with my eight." He showed that card, and then led the eight of clubs. SB covered with the nine but, after considerable thought, RR played the ten and SB was one down."
"DIRECTOOOOOOOR", bellowed SB in his usual manner. The TD arrived.
"There was a breach by the Chimp of Law 66B which states: Until a card is led to the next trick, declarer or either defender may inspect, but not expose, his own last card played." He paused for breath. "Law 9A3 does allow CC to prevent an infraction such as a LOOT, but not by showing the last card played or by making the statement that he had overtaken the seven of diamonds." "That remark conveyed UI to RR, and he would have wondered why the Chimp did not want him on lead." He paused again. "Not that RR should ever wonder why anyone would not want him on lead, mind you," he continued meanly. "The Chimp should have called the TD if RR had disputed whose lead it was."
"The effect of the exposure of the card, and perhaps more so, the remark, was to focus the Rabbit's attention on what would have happened if he had been left on lead and why the Chimp did not want him on lead. Even someone with his limited ability could then work out that South had the king of clubs - or he would have a nine count." "Without the remark and exposure, RR might well have played the ace of clubs, playing his partner for the king; or he might well have led to the next trick." He concluded: "In addition, there should be a PP on East for a breach of Law 66B, which is, effectively, a 'may not' Law". "If RR had led to the next trick, then I would have also made, in three different ways - which you will enjoy working out," SB concluded.
