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.
