¹ Both minor suits
After 4NT Belladonna had a problem. In the end he took the excellent (in view of the distribution) decision to merely bid 5♦. No one could have blamed him if he had tried a slam.
On the other table the bidding was exactly the same (south was Paul Soloway) and so was the lead: ♥2. That meant declarer play and defensive play would decide this deal...

Belladonna tried ♥10 in dummy, which held the trick. He cashed ♦A and ♦K and saw he had a trump to lose. To avoid losing two club tricks (especially since in view of the bidding it was quite likely east held both ♣A and ♣Q) Belladonna worked towards an end play in which he wanted to throw east in the lead with ♦Q after having stripped him of his hearts and having eliminated the spades in NS. East would then have to play into the club tenace. East of course was not here to help declarer, so Belladonna had to take care east would not have any choice once he gained the lead with ♦Q.
The declarer cashed ♥A and crossed to ♠A. He now had to cash as many hearts as east had, because he was not able to eliminate the spade suit (by way of a ruff) first. Belladonna cashed ♥K, both west and east following with a small heart. He now knew the exact distribution, since the first trick had shown west to have ♥J, the last heart that was still out. Belladonna now ruffed ♠J in dummy and as planned threw in east with ♦Q.
East had to play either a spade giving declarer a ruff and discard (south discarding a club, north ruffing) or a club into the tenace. Belladonna had eleven tricks.

Well played, sure enough, but Eisenberg himself, a world class player, will certainly have considered it a blunder not to have dropped ♥J in the third round of hearts. That would have forced Belladonna to guess who had the fourth heart. Had he guessed it was with east, he would have played the fourth round of hearts first, before ruffing ♠J (he would have had to, to extract east's safe exit card). In the actual lay-out east would have ruffed that trick and got safe off lead with a spade. He could then have waited for two club tricks.
Dropping ♥J by west in the third heart trick is an application of an old rule: 'If it does not cost, play the card you are known to hold as quickly as possible.'

On the other table Soloway played ♥A in dummy on the lead, after which he lacked entries in the south hand to ruff both a heart and a spade. The throw-in was therefore not possible and he went down.
