In the Daily Bulletin of the Bridge World Series 2010 (the combined World Championships for Pairs and Open World Championships for teams), played in Philadelphia in October, Zia Mahmood offered an unusual quiz. It featured a deal from the individual round of the recently concluded 2010 Buffett Cup, which was played in Wales. It was the third time that this biennial clash — similar to the Ryder Cup in golf — between Europe and the USA took place.
To set the scene, here is the dummy and declarer's hand (rotated from the original positions):

		♠	10 7 5
		♥	A 9 6 3
		♦	J 5 2
		♣	8 7 2
		♠	A K Q 9
		♥	K 7 5
		♦	K 9 7 3
		♣	J 4

West led the ♠3.

Zia reports that four different declarers played the ♠10 at trick one. When it held, each of the four took a different line of play, as follows:

Declarer A played a low club to the ♣J and West's ♣K. The deception was not effective, however, and declarer finished three down.

Declarer B played a low diamond to his ♦K. When that lost, he too was three down.

Declarer C played a second spade to hand, noting East's discard of a low club, and exited with a low diamond from hand. Declarer C made 1NT, later guessing to play East for the ♦10.

Declarer D also played a second spade, and East at this table also discarded a low club. A third round of spades brought another club discard from East, after which declarer D exited with a low club. He also made 1NT.

The full deal:

		♠	10 7 5
		♥	A 9 6 3
		♦	J 5 2
		♣	8 7 2
♠	J 8 6 3 2			♠	4
♥	Q J			♥	10 8 4 2
♦	A 8 4			♦	Q 10 6
♣	K 9 6			♣	A Q 10 5 3
		♠	A K Q 9
		♥	K 7 5
		♦	K 9 7 3
		♣	J 4

The quiz that Zia has put forth is regarding the four declarers: himself, Bob Hamman, Boye Brogeland and Antonio Sementa. See if you can match the name to the line of play.

Solution

Declarer A was Norwegian star Boye Brogeland.
Declarer B was Italian star Antonio Sementa.
Declarer C was American superstar Bob Hamman.
Declarer D was Zia himself (former Pakistani, now a US citizen).

Comments Bridgevaria.com:
1. The deal shows how effective it can be to cash your long suit — or even only a few tricks of it — in no-trump contracts. East can hardly be blamed for discarding clubs, but after the second EW had, apart from the long shot of the third heart, no setting trick left!
2. It's risky (and cocky) to contradict a bridge player of Zia's stature, but still: how did A (Brogeland) and B (Sementa) end up down three? Surely EW couldn't take more than five clubs and three diamonds, meaning declarer was only down two...?
