This game is played by millions of people every day, both to find additional income or just for fun. But in fact not everyone who plays poker with these goals gets according to what they have planned. Some people actually experience losses after playing. They unconsciously develop the logic of gambler's fallacy that causes them to play poker without using strategy. This research made a system that can prove the defect of gambler's fallacy and made a tool for playing poker. The processed dataset is a dataset containing information of cards used in poker and their probability of occurrence. The method used in this research are iterative deepening search tree and decision tree. The main results of this research is a tool that can provide insight as a basis for decision making. However, this tool has not been able to prove its capabilities in helping to increase the winning percentage, so that further study is needed. In addition, this study also shows that playing with gambler's fallacy logic only gives 48.13% wins of 6,000 trials. These results proved that using gambler's fallacy logic in playing poker is a mistake.
