The player's 'playing hand', which will be compared against that of each competing player, is the best 5-card poker hand available from his two hole cards and the five community cards. Betting begins before any of the community cards are exposed, and continues throughout the hand. Five community cards are also dealt into play. In Texas hold 'em, a starting hand consists of two hole cards, which belong solely to the player and remain hidden from the other players.
