Leduc Hold’em is a variation of Limit Texas Hold’em with 2 players, 2 rounds and a deck of six cards (Jack, Queen, and King in 2 suits). At the beginning of the game, each player receives one card and, after betting, one public card is revealed. Another round follow. At the end, the player with the best hand wins and receives a reward (+1) and the loser receives -1. At any time, any player can fold.
Our implementation wraps RLCard and you can refer to its documentation for additional details. Please cite their work if you use this game in research.
As described by RLCard, the first 3 entries correspond to the player’s hand (J, Q, and K) and the next 3 represent the public cards. Indexes 6 to 19 and 20 to 33 encode the number of chips by the current player and the opponent, respectively.
|0 - 2||Current Player’s Hand
|3 - 5||Community Cards
|6 - 20||Current Player’s Chips
|21 - 35||Opponent’s Chips
|+raised chips / 2||-raised chips / 2|
The legal moves available for each agent, found in
env.infos[agent]['legal_moves'], are updated after each step. Taking an illegal move ends the game with a reward of -1 for the illegally moving agent and a reward of 0 for all other agents.
