Ask how a hand was bid, where the field split, how a contract scores, or how a player has done.
The match stays on the exact count once 15 decisions are there. A wider window is used only when the sample is thinner. 0 is exact.
Passes may come before the auction you typed. A board is kept when each named call was chosen at least that many times.
Make rate is the share of times the contract took at least what it bid. The score is North-South. Opening leads appear when both level and strain are set.
