In a real poker game, one player can take actions of different styles in different situations. In this paper, a novel method is proposed to quantify and model the opponent's style in corresponding situation of a hand. Based on the proposed representation of Action Pair, the value of the style can be calculated and stored as "experience". When making a decision, the specific style will be obtained from the "experience". The style and the observable information will be used to estimate the value of the opponent's hand. In experiments, the obtained "experience" validates the correctness of our assumption that a player does not show an invariable style in all situations. The experimental results show that the agent player using our method can predict the value of the opponent's hand and earn more money in fixed hands comparing with the original agent.
