This repository contains programs that compute the winning probability of each player in Texas Hold 'em, given the pockets of all players and optionally community cards.

Usage

holdem <Pocket1> <Pocket2> [...] [+<Community>]

PocketN/Community is a sequence of cards. Each card is specified by two characters like 2S or JH: the first character indicates the rank (T for 10; obvious for others) and the second the suit (S for spades, H for hearts, D for diamonds, and C for clubs).

Examples

Preflop with 4 players; the first player (10♣2♦) will win the entire pot (without any ties) by 17.66% and lose the pot by 80.68%:

$ holdem TC2D 2HQH 7D5D 4H2S
[0] TC2D:  17.66% /  80.68%
[1] 2HQH:  35.09% /  63.25%
[2] 7D5D:  34.06% /  65.11%
[3] 4H2S:  11.53% /  86.82%

If the flop turns to be 3♦3♥A♦:

$ holdem TC2D 2HQH 7D5D 4H2S +3D3HAD
[0] TC2D:   6.10% /  86.34%
