I'm building an AI for No Limit Texas Holdem. I'll periodically share some results/resources in this repo.

Game Logic

All rules of NLTH is implemented. You can build a bot by creating a subclass of BasePlayer. BasePlayer will just play randomly. The code below will shows how to simulate a 6MAX game with 1000 hands. The blind is 1/2.

STACK = 200
NUM_PLAYER = 6
SIM_NUM = 1000
players = [BasePlayer(STACK) for _ in xrange(NUM_PLAYER)]
dealer = Dealer(players)
print 'simulating %d hands' % SIM_NUM

for i in xrange(SIM_NUM):       
    dealer.play()
    
balances = [p.stack - p.balance for p in dealer.players]
print balances

Allin Equity(allin_equity.dat)

When headsup if allin preflop, there's 1,712,304 boards. I simulated each board every possible 812,175 confrontation. Each line describe the confrontation of one pair of hands. For example,

5s4h JsTh 598173 1092422 21709

Means when 5s4h and JsTh go allin preflow, 5s4h will win 598173 times and lose 1092422 times. For 21709 times, it will be a tie.

This data is vital to any range equity calculation and solving many games. 'Jam or Fold' with short stacks, for example.
