Collusion at poker
Collusion Collusion is a form of cheating. Players will work in a team to try to gain an advantage over the other players. They will somehow signal to each other what their cards are. They will then use this information to gain an unfair advantage. Collusion is illegal. It is sometimes hard for brick and mortar cardrooms to detect colluders, but online poker rooms can track potential colluders because they can review hand histories.
