Cooperative partner system of imperfect information game

This paper aims at the construction of a cooperative partner system that plays a seven-card stud poker game with a human partner against an opponent player. If a human player needs some advice on a game, the partner system gives a human partner player strategy to take in a game and its grounds. A human player can also ask some questions about the current situation of a game. If a human player tries to take different strategy from the one presented by the partner system, the partner system calls human player´s attention to the presented strategy with its grounds. This paper also performs subject experiments to confirm the usefulness of the presented partner system, where each subject plays games with/without the partner system.
