a rusty Texas Hold'em poker odds simulator

Installation

brew install rustup
git clone [email protected]:ocisly/odd.git
cd odd
rustup -V
cargo install --path .

Usage

odd <hole-cards>... --opponents <opponents> --permutations <permutations> --seed <seed>

When all the players' hole cards and all five community cards are known, odd detects what hand each player holds and determines the winners:

odd Ad Ks 8h 8s --board 8c Ah As 9c 9h

player 1 was dealt: A♦️ K♠️
player 2 was dealt: 8♥️ 8♠️
flop: 8♣️ A♥️ A♠️
turn: 9♣️
river: 9♥️

43 cards remain.

player 1 has Full House, As full of 9s: A♦️ A♥️ A♠️ 9♣️ 9♥️ (winner)
player 2 has Full House, 8s full of As: 8♥️ 8♠️ 8♣️ A♥️ A♠️ (lost)

Otherwise, odd estimates the odds of winning for each player by generating a configurable number of random deck shuffles to simulate a range of possible scenarios:

odd Ad Ks 8h 8s --board 8c Ah As 9c

player 1 was dealt: A♦️ K♠️
player 2 was dealt: 8♥️ 8♠️
flop: 8♣️ A♥️ A♠️
turn: 9♣️

44 cards remain.

player 1: win 15.90%, tie  0.00%, loss 84.10%
player 2: win 84.10%, tie  0.00%, loss 15.90%

Additional opponents with unknown cards can be specified:

odd As Ah -o 1

player 1 was dealt: A♠️ A♥️

50 cards remain.

player 1: win 82.10%, tie  0.54%, loss 17.36%
player 2: win 17.36%, tie  0.54%, loss 82.10%
