Matchpoints; Table Result 6S? Lead ♦J
SB quite likes individuals as it gives him a chance to be rude to 24 partners in one evening. Such was the case at a North London club this week, and featured a most remarkable safety play by SB, the like of which has never been seen before. Despite the fact that the TD stipulated "Simple System" with just ordinary Blackwood and Stayman, Molly the Mule, North, was not to be budged from her losing-trick count and 1430 RKCB and SB was soon in the hopeless slam. He won the diamond lead with the ace and led the king of clubs, intending to get rid of his diamond loser quickly. The rabbit, West, ruffed this with the ace of trumps, but Colin the Corgi, East, had been listening to the bidding and quickly asked "No clubs, partner?" "Oh, dear", replied RR, "I thought declarer had led the king of spades. The lighting is not as it should be." "I noticed", replied SB, "and that clearly affected my partner in the auction as well, so it cuts both ways," he retorted. "I think we ought to have the director," he continued, and Oscar the Owl, a keen student of WBFLC minutes, arrived.
"A non-established revoke", guided SB, "and I think you will need all the minutes on MPCs", he continued, noticing that the contract now had very real chances. "Leave it to me, please", OO chastised. "The ace of spades is now a MPC and must be played at the first opportunity". If East gains the lead, there will be lead penalties." He stopped, keen to be sure he had included everything. "And the fact that West has the ace of spades is UI to East, but the fact that it has to be played at the first opportunity is not." "And I shall remain until the MPC is played".
SB saw a significant extra chance. He would make the contract anyway if the king of spades fell under the ace, and it was clear that RR did not have both the ace and king of spades, or even he would have noticed that the card led was the king of clubs. He also thought that RR had won what he thought was the first round of trumps without thought, and he believed the trump layout was as it was. He therefore discarded a diamond on the second round of clubs, ruffed a diamond, and advanced the queen of spades! CC, East, had been fairly confident of defeating the contract until now, but foresaw a major problem at this unexpected development. "You stated that I am not allowed to know my partner has the ace of spades, but I am allowed to know that it has to be played on this trick", CC enquired. "Correct," replied OO, "and that is all I can tell you." "You have to make the best you can of the Laws according to Lear". After some thought, CC played low, and SB was one down.
"Now we move on to the catchall", continued SB:
"50E3. If the Director judges that the exposed card conveyed such information as to damage the non-offending side he shall award an adjusted score."
"I submit that CC used the UI of seeing the ace of spades to play low. From his point of view, his partner might have had Jx of spades (we were playing four-card majors as required by simple system) or even the stiff J. The only time it would be wrong to cover would be when his partner had stiff ace, which he knew to be the case only from the UI." He paused for breath, "You should judge that the exposed card conveyed such information as to damage the non-offending side and I think we can write down 6S=, can't we, OO?" "And if you don't rule under 50E3, there is always L23; RR could have known that playing the ace of spades on the king of clubs could well damage the non-offending side".
How would you rule?
