about me

I'm just a pretty average club player in the UK.  However, I am Chairman of Woking Bridge Club in Surrey, UK, which is a friendly ethical club, so do join us if you fancy a game while visiting the area.

Also, I have a Ph.D. in Statistical Mechanics, and know how the odds of suit distributions really work.

Define Your Bids Before I Tell You My Defense
This sort of thing is just why I will never trouble myself to play the same sort of shenanigans bridge that many of you seem to.
Good Director Story
After East accepts North's insufficient 1H, my second bid as South would be to repeat my 1NT opening - and away we go! Secondly, surely the director should not advise North as to whether a particular bid (2C in this case) is comparable or not before North chooses what call ...
1!C - 1!H - rebid??
Since I play 12-14 NT, I'd open 1NT to avoid the inevitable rebid problem. So, using the system described, it's a 1NT rebid.
ATB: Slam vs 3NT
Put me down for a 4 splinter by North on the second round. The bidding so far makes it look like a 30 point deck, and I have 17 of them and partner has opened. I have already indicated 4 Spades, and my splinter says I am looking for ...
Space: Beyond the Frontier
Hi Christopher. Yes, of course, if we had been able to discover that East held 5 minor suit cards in addition to 6 Spades, then the 3=3 Heart split becomes impossible, and the finesse becomes the better proposition. I hope you enjoy the book. It was something I penciled ...
Space: Beyond the Frontier
Hi Christopher. I am sorry to have to say that there are a couple of errors in your comment. Firstly, the two Diamonds played are irrelevant. E/W have to hold 12 Diamonds and Clubs between them to make up their 13 cards. You should only include in Empty Spaces ...

Why make it all so complicated? If East has 6 open spaces and West has 4, the ratio between 2=4 and 3=3 clubs is precisely 9:8. So the relative likelihoods of the finesse succeeding is 6, and of the bang succeeding is 7. If East has 6 ...
Ax opposite KQTxx
David C., may I refer you my article at which deals with exactly this calculation? In this article, the open spaces are 11 and 7, but the method of calculation is identical. By the way, you can check that your percentages 42.86 and ...

Thank you, Craig and Marty, for the reference. It is indeed BY FAR the best shortcut, and for those who prefer math to hiking, an hour or two of combinatorial algebra will proof that it is mathematically correct - and there are no rounding errors.
Club Library Books?
I recommend the series of little books by Reese & Trézel, each on a single aspect of card play.
