about me

Bridge is like the world, full of uncertainty. Maybe this is why I am so fascinated about it. Thanks BW and all my partners and opponents, I am still learning and making progresses steadily. Besides bridge, I try to understand the mathematical nature of life. I don't know which is more difficult, but am sure both requires a lifetime of exploration.

Best line to make 4 spades
K, J. If LHO wins, I will finesse spades. If RHO wins, I cash the A next time. I try not to lose two spades before considering any end game play.
Best Line
Suit combination
Oh, I did count J9 in my calculation. So my rates still stand.
Suit combination
Without the 6, I cash the Ace and lead low toward the queen, that gives 50%. If I have both 6 and 5, I run the 10 from dummy. I cover if RHO covers. If it lost to LHO, I run the 8 next time. I would lose when LHO ...
Slam bid problem
You are right. Say east has no Q and has KQJxx KJxxxx, is he more likely to open 1S with such a minimum hand?
Slam bid problem
I don't know the exact chance of slam. West has 6+ spades, so he rates to have one or two spade honors. Thus east should have all remaining honors. The K is onside. It comes down to see whether diamonds break. But it looks like I can handle west ...
Patterns VI - Suit Combinations
Every thing involves prior distribution in bridge play is restricted choice. Say West has 23 tight, he has to play them. If he has 234, the chance you see him randomly play 23 is 1/3. This is exactly why we cannot put the same weight in the cards played ...
ROTS: Your Lead from !SA85 !HJ943 !DKJ9642 !C --
Do I know West must have the K? If not, I would cash all trumps, discarding 2 diamonds and 1 heart from dummy before cashing 3 rounds of hearts. I would succeed if the J drops or East has the K (a squeeze on his diamonds and clubs). But I ...
Patterns VI - Suit Combinations
Kurt H and David B: Thanks for pointing out the problem in my calculation. I guess it was the demon of restrictive choice playing on the major suits. I had thought we could skip the simulation suggested by Kit as long as we agree on theoretical calculations, of course Kit ...
Patterns VI - Suit Combinations
Kurt H., I agree with you we should not forget the prior probability. I did put the prior probability on top of my calculation. The prior odds is 2:1 given by restricted choice, that's why I adjust my ratio of 5:6 to 5:3. Don't you ...
