On arrival in Amsterdam (at the White House venue) we are told we will be playing at table 1 North-South all the time. Furthermore all our deals are shown live on the internet (BBO). This way, the organisers tell us, kibitzers can enjoy the play of the winners even more. More pressure, I am even beginning to get nervous.
This is the first deal (for the reader's convenience the first two of the following three deals are rotated, therefore I am not South):

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

¹ transfer to 3♣
² club fit (without it North would have obliged by bidding 3♣)
³ heart guard, no diamond guard (holding a diamond guard South would have bid 3♦)
⁴ spade guard, no diamond guard (holding both North would have bid 3NT)

An instructive deal to start with.

The NS-agreement to show guards after the transfer, worked very well. After 3♥ and 3♠ South knew there was no diamond guard, hence his 5♣ bid (by the way: already after 3♥ North knew about the missing diamond guard, so 3♠ presumably promised a four card suit as a proposition for a 4♠ contract in a 4-3 fit).
The 5♣ contract was unbeatable and South made an overtrick since West had the ♠K and the ♠9 came down in time, so South's heart loser disappeared on dummy's fourth spade.
At the other seven tables North played 3NT and was defeated on East's diamond lead.
And so we were bottom of the list after the first deal. Phew, quite a start.

The most important round is the one against the manager or our team (Team 'Orange'), Eric Laurant.
Losing that round would mean we would be reminded to it for the next year or so. Fortunately already in the first deal we took the mickey out of him.

		♣	A 5

¹ 9-12 HCP

After my 1NT opener bidding 6♠ turned out to be too difficult for NS. We won 6 IMPs on the deal since about half of the NS-pairs had arrived at the slam.

Then it happened. We came in a flow: anything we tried worked out well. Nothing we did could turn out wrong. But to be honest, don't try this at home!

		♣	Q J 10 9 8 7 6 5 4 2

¹ 1♦, 1♥ and 1♠ all would show a five card suit; this 4-4-4-1 was therefore the exceptional case in which East couldn't but open 1♣ on a singleton

My 5♣-bid was daring but Bas' 6♣... wow! Even at the table already he was applauded by the kibitzers.
Needless to say we eventually won the tournament. The bonus was that this time we were allowed to keep the prize money.
