41poker is a JavaScript toolset for Texas Hold'em, including
- efficient hand evaluator for 5,6,7 cards
- hand strength simulator for preflop, flop, turn
- console/browser gameplay
- smart agent (to be implemented)
- ...
Some development notes are published in Japanese at Qiita. Contact me @41semicolon at Twitter.
