"Hi SB and MM", said ChCh arriving at an online memorial game at the North London club recently, 75 years after the end of World War II. "We are weak NT and three weak twos. Although I think we should play strong, RR, after your last effort where you went for 800 in a cold 1NTx."
"Weak NT, 4 card suits", responded MM.
RR opened a weak NT, but, distracted by the recent discussion with ChCh, explained it as 15-17. ChCh raised to the vulnerable game and MM led the five of spades to the ace and South's two. "Shouldn't you have bid Stayman, partner, as we could have a heart fit?" asked RR while SB was thinking but ChCh just gave him a withering look.
SB paused to think, recognising it as a potential surrounding play of leading the jack of clubs, but RR would have too much for that to work, and in any case his partner might have ♠KJxxxx when a switch could be catastrophic, so he continued spades. MM won the second spade and cleared the spades, hoping the ace of clubs was an entry.
RR's mind had wandered and he ruffed this trick with the ♥T in case, East could not overruff. and was pleased when East discarded a club. He now tried to draw trumps by leading a heart from dummy, and said "My screen appears to be frozen, it won't let me lead from dummy." "You are in hand," responded ChCh. "No, I am sure I ruffed the last trick," said RR. "You are playing in no-trumps", RR, responded ChCh. "I suggest you re-read lesson 1 of Bridge for Beginners, although "re-read" might be undue flattery."
There was sheepish silence from RR, but he recovered his composure well enough to cash the hearts from the top, and was surprised when his 7 won the third round, as he was sure the ten was still out. He emerged with five heart tricks, a spade, and three diamonds despite the bad break, for a virgin +600 and 11 IMPs in.
"You should duck the second spade, MM, when he can't discard the blocking heart", started SB, East. "And you mis-announced your 1NT as 15-17, RR". He repeatedly banged on the "CALL DIRECTOR" button on his keyboard, causing the table to crash.
Eventually OO arrived and restored the table. "RR mis-announced 1NT as 15-17" SB began. "With the correct announcement, I would have switched to the jack of clubs beating the contract two." He paused for breath. "In addition, ChCh participated in the play as dummy, pointing out that declarer was in his hand and that it was a no-trump contract."
"Self-serving" replied ChCh, North. "You would probably still have played for partner to have KJxxx(x) in spades, and in any case I announced our NT range at the start of the round." He concluded. "And my comments during the play had no effect on the result. To dot the "i"s and cross the "t"s, I don't see the announcement so there is no UI either."
How do you rule?
