The year is 1970 and Italy rules the bridge world; the Blue Team is invincible.
In Winnipeg the Italians play the Dallas Aces, a specially formed American team of professionals that is hoped to be the first team to beat the Italians in 15 years.

Belladonna's 5♣-bid is extremely aggressive. In fact he goes to 6♦ on his own.
Eisenberg leads the ♣8. Later he said this was the best played deal against him ever.

On seeing the dummy Belladonna rose from his chair and paced up and down the room for five minutes, smoking heavily while thinking. He did not believe East to hold an honour card like the ♠K next to his club suit. After all, East had opened pre-emptively above 3NT and he will not be inclined to do so if there is a chance of making 3NT.
Furthermore, in view of East's pre-emptive Belladonna did not expect even one of the major suits to be 3-3 (both major suits 3-3 was even impossible).
Belladonna therefore concentrated on a lay-out in which both the ♠K and ♠J would be in West and both major suits not 3-3.
As so often Belladonna, arguable the best dummy player ever, was right.

In the first trick he inserted dummy's ♣Q and ruffed East's ♣A. He continued with the ♦A and then crossed to the ♦J. He shed the ♠10 on the ♣K and then cashed all his trumps.

On the last trump West, Eisenberg, was in deep trouble:

When Belladonna played the ♦7, Eisenberg could not discard the ♠9, since Belladonna (who had been careful to keep all four spades in dummy) would play the ♠A and then the ♠Q, thus establishing dummy's ♠8 and ♠7 (♥A was the entry card).
So Eisenberg threw a heart. Belladonna now played the ♥A, ♥K and another heart. This was a dual purpose play: Belladonna's fourth heart was now good and at the same time West was thrown in to play in the spade tenace.
(West's discarding had been the best possible: had he kept all four spades, South would have made four heart tricks and his contract).

As mentioned before: to this day Billy Eisenberg thinks this the best played deal against him.

At the other table Jim Jacoby was also in 6♦ as South. The first trick was identical: club lead, ♣Q, ♣A ruffed. Jacoby now crossed to the ♦J in order to play a spade to the ♠10. He won the heart switch, discarded a heart on the ♣K and played a spade to the ♠Q. Two down...
