Suit Combination Solver
A suit combination is the cards you and dummy hold in one suit, together with the number of tricks you need from it. The solver works out how to play it: enter both hands and a trick target, and every card you can play shows its exact chance of taking those tricks. The figure covers every possible lie of the missing cards, each weighted by its real odds, with vacant places and restricted choice built in. It is worked out over every layout by an exact solver for the suit, not estimated from a sample of deals.
