How are suit break probabilities calculated?
From exact combinatorics: the number of ways the missing cards can be dealt between the two unseen 13-card hands. Nothing is simulated.
Do suit break odds change during the play?
Yes. These are prior odds. As opponents show out or show length in other suits, the live odds shift (vacant places).
