In the Steps of Tuszynski

You may recall this deal from Monday's opening round.
In the match between Israel and Argentina, a deceptive lead reaped a huge dividend.

West led the jack of spades, but declarer made no mistake, going up with the ace and cashing two rounds of hearts. The club finesse was right, so +420 for Israel.

North's 2NT promised a good heart raise or better.

West declined to overcall and also refrained from doubling Three Diamonds. There was a fair chance that declarer would now have ducked a spade lead, allowing East to win and switch to a diamond, but West had a different idea in mind when he led the nine of hearts!
Declarer played dummy's tem and took East's jack with the king. He crosssed to dummy with a winning club finesse and ran the eight of hearts.
It must have been quite a surprise to see it lose to the queen and Israel had gained 10 IMPs.
There was a similar hand in the final of the 2000 Olympiad between Italy and Poland where Tuszynski made a similarly brilliant lead. However, experienced declarers do not consider it likely that a defender will lead a singleton trump and the redoubtable Lorenzo Lauria took the winning view by dropping the queen.
