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:
 The game type and limit for the table (for example, limit Texas hold 'em $3/$6).
 The names and seating positions of all players at the table.
 The size of player stacks at the beginning of hand.
 Any hole cards known to the requestor.
 Any cards dealt face up on the table.
 The betting actions of each player in each betting round.
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.
