Hand history
A hand history is a record of the action in an online poker hand. These records are generated by poker sites, and used internally to track player behavior and provide a verifiable log to resolve player disputes. If the poker site and client permit it, plain text versions of hand histories may be made available to players, which facilitates personal record-keeping and the sharing of interesting or problematic hands. A typical hand history will contain the following information: While the internal version of the hand history will display all hole cards, the version made available to a  player will show only those of the player himself and any hole cards revealed at showdown or voluntarily shown by a player. Some commercial software products make use of hand histories to assemble a record of a player's winnings and losses, and track their playing habits as well as those of their opponents.
