Apolinary Kowalski provided this tale of an imaginative switch by Claude Delmouly in the second session of the Mens event, but it was Geir Helgemo at another table who found the most accurate defence:

Board 6. Dealer East. EW Game J 6 A J 10 8 3 Q 6 2 K J 8 5 4 3 2 K Q 10 8 7 Q 5 K 9 6 2 J K 9 7 10 9 7 5 3 2 A A 9 7 4 A 10 8 5 4 3 Q 6 4 West North East South Lantaron Jas. Hackett Delmouly Kowalski 1 2 2 3 3 Pass Pass 4 All Pass

West North East South Kholomeev Chemla Helgemo Freeman 1 2 Pass 2 Pass 3 3 4 All Pass

West led a spade against Kowalski's Four Diamonds. Declarer won and returned a spade to East. Delmouly found the good switch of K. Declarer won this and also did well by leading Q covered by the king and ace. When the jack fell from West, Kowalski tried to get back to dummy by playing a club. Delmouly won, put his partner in with Q and received a club ruff to defeat the partscore.

Note that it does no good for declarer to duck K when it is led. East will cash A and play a second heart. Declarer wins and plays trumps: Q, K, A, J. But now he cannot get back to dummy.

However, as Kowalski spotted he did have a chance to make. After winning the ace of trumps he must play a heart. West wins and plays a club, but now East is end-played into conceding an entry for the trump finesse. Sadly this reveals a slight flaw in Delmouly's defence. He should have cashed A before making the switch to K - then declarer cannot succeed.

And guess what, that is exactly how Helgemo defended against Freeman. Freeman won the heart switch, began trumps by playing Q, K, A, J, but when he tried to get back to dummy with a club, Helgemo ruffed, put his partner in with the Q and received a second ruff. Two off!
