dear all, I have, say, a 100 bridge deals and I want to calculate for each of them the probability of making different contracts (several per deal, say 3NT by N, 4H by S, 2H by S...), assuming everyone plays correctly and assuming that you only know the declarer's and dummy's hand. Say, if the declarer wins if and only if the king of spades is on his/her left hand side, the probability will be 50% and so on. Do you know of any software that would allow me to obtain these probabilities? Ideally, with some non-graphical interface so that we could automate data entry. many thanks in advance. michal
