This page is the site's highlight. Knowledge of card combinations' odds has always been a must. Most bridge books assume that these tables are known, but this is not always the case. What's more, the point to which these odds change when some of the opponents' cards are known, is not clear. 

That is, missing Qxxx, should I play for the drop if West has opened a five-card major,  a six-card weak-two or a seven-card preempt (and East has one, two or more of these cards)? And what about 3-3 and 3-2? The number of these issues does not permit dealing with all of them in print. 

The program to which this click will lead you, analyses any given set of missing cards, considering the number of known cards in any of the opponents' hand, and produces a table you can use to evaluate a way of playing.

You can now find the probability of two or more suits' combined break. For example, missing in the same hand Qxxx in one suit and Jxxxxx in another, what are the actual odds that both (or none, or one) of them break favourably? Remember that the break of one suit affects that of the others.

Note: Do not overestimate these tables. Playing with the odds (only) is very rarely the right thing to do. On the other hand, it is always the best excuse to the partner and/or teammates.
