Bridge Simulations: April 2009

http://bridgesimulations.blogspot.com/2009_04_01_archive.html

Monday, 27 April 2009. Just a quickie. Here's a hand which has done the rounds today. You hold, at green (non-vulnerable vs vulnerable):. Yep, that's nine. Clubs Do you open it 1. I'm not going to type away at length about what I think is best, but you might be interested in the probabilities of what can and can't make on the deal. Use them as you see fit. Will make about 54% of the time, 6. 3NT will make by your hand 31% of the time. In 53% of cases, 3NT will make while 5. Oppo can make 5. 31% and in 5.

Bridge Simulations: January 2009

http://bridgesimulations.blogspot.com/2009_01_01_archive.html

Thursday, 8 January 2009. Is going off in a game worse than missing an overtrick? It's been a while since the last post, but I promised neither frequency nor regularity so won't apologise! I've just not been doing very much simulating recently. Somebody did ask me a question towards the end of last year so I might post on that subject at some point. Anyway, on to today's topic, which isn't even about simulations at all. And you tell him so. What am I talking about? East West Ways %. 2 Qxxx x 4 11.30.

Double Asymmetries

http://bridge.thomasoandrews.com/deals/tenaces/all.html.gz

From the Real World. From the Real World. Double Asymmetries ♥. We've all seen contracts which can make more tricks declared from one side than the other. A typical example is:. East can set it with a club lead. But when declared by South, both slam makes, scoring five diamonds, four hearts, and three spades. A holding which can only be profitable attacked from one side. This idea led me to ask the question, "Are there deals which play better by North in, say, hearts, but better by South in notrump?

Par Zero Deals

Two en passant Coups. Two en passant Coups. A Complexity Four Example. A Complexity Four Example. Par Zero Deals ♥. Are there any deals where neither side can make any contract? This comes up in bridge discussions now and then, and the answer is, yes. The easiest example is:. In any contract, the defense can take eight top tricks, which means that not only can nobody make any contract, but all contracts end up down two. The obvious, perhaps tautological, theme in these deals is. Trump promotions - if the...

Bridge Simulations: June 2009

http://bridgesimulations.blogspot.com/2009_06_01_archive.html

Wednesday, 3 June 2009. If you have an idle moment, please can you simulate expected number of tricks holding 0,1,2,3. etc. HCP opposite a balanced 20-22 HCP (a) when the fit is 5-4 (b) when the fit is 6-4? This one shouldn't be too tricky. Let's give ourselves a 20-22 2NT opener with four hearts and give partner a hand with five or more hearts. He transfers and you are wondering whether you should super-accept or if the 3 level is the right place to play. Pts 4H 3H tot. 0 55 57 188. 1 160 145 388. Now, ...
