I'm surprised there is no bulletin. In round 5, the Wolfarth team beat Allfrey 63-60, thanks in part to a psychic double by Valio Kovachev. He sent me this story earlier today, which I have included with minor editing.
You are playing a 32 boards knockout match against very good opponents. After 24 boards your team is 20 IMP[s] behind. The last eight boards don’t start well either — Tony Forrester makes an expert play to bring home a 4
♥ game with [a mere] 22 points and a 4-4 fit.
So it looks like you are now trailing 27 or 30 IMP depending on whether your teammates have reached that game. In fact they [went down one in game].
Now for the first time in my life I made a psyche double. I was in second position and held:
The auction by Tony Forrester and David Bakshi began
1
♦ - Pass - 2
♣ (FG) - Pass
2
♥ - Pass - 3
♥ - Pass
4
♣ - Pass - 4
♦ - Pass
4NT - Pass - 6
♦ - Pass
6
♥ - Double (!) - Pass - Pass
When the double [returned] to Tony, [a] great player with a lot of imagination, he agonized for three minutes staring at his hand (East):
Tell me now dear reader would you pass, and face a dummy like (West)
only to find out that Valio's double contained 5 or 4 good trumps?
Anyway, his final decision was wrong — he moved to 6NT as is [customary] nowadays only to be doubled again for -4 (-800) as he had no stopper in spades. David's hand was (North):
Indeed, 6
♥ had some play — but tell me honestly how would you guess the
♥Q after hat double?
That swing created 17 IMP[s] for our team — just the breath of fresh air that we needed. The final result was 63-60.
Most of the time the game is just to sit and bid your hands waiting for the opponents to make a mistake, but sometimes you need to push them to the edge where it is easier to fall out.
Some final words. That great player Forrester, who isn't famous for his nice behaviour, came to me after the segment and said: “Great double”.
