Explanation of Collusion
Although every player at a poker table should be playing solely for himself, it’s possible to gain an edge by covertly working together with another player at the table. Note that this is against the rules of all poker networks and live games, it constitutes cheating. Getting caught will usually result in a life-time ban from the network or casino.
