In the poker game of Texas hold 'em, a starting hand consists of two ''hole cards'', which belong solely to the player and remain hidden from the other players. Five community cards are also dealt into play. Betting begins before any of the community cards are exposed, and continues throughout the hand. 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. Unless otherwise specified, here the term ''hand'' applies to the player's two hole cards, or ''starting hand''. == Essentials == There are 1326 distinct possible combinations of two hole cards from a standard 52-card deck in hold 'em, but since suits have no relative value in this poker variant, many of these hands are identical in value before the flop. For example, and are identical in value, because each is a hand consisting of an ace and a jack of the same suit. Therefore, there are 169 non-equivalent starting hands in hold 'em, which is the sum total of : 13 pocket pairs, 13 × 12 / 2 = 78 suited hands and 78 unsuited hands (13 + 78 + 78 = 169). These 169 hands are ''not'' equally likely (see ''Poker probability (Texas hold 'em)''). Hold 'em hands are sometimes classified as having one of three "shapes": * ''Pairs,'' (or "pocket pairs"), which consist of two cards of the same rank (e.g. ). One hand in 17 will be a pair, each occurring with individual probability 1/221 (P(pair) = 3/51 = 1/17). * ''Suited'' hands, which contain two cards of the same suit (e.g. ). Four hands out of 17 will be suited, and each suited configuration occurs with probability 2/663 (P(suited) = 12/51 = 4/17). * ''Offsuit'' hands, which contain two cards of a different suit and rank (e.g. ). Twelve out of 17 hands will be nonpair, offsuit hands, each of which occurs with probability 2/221 (P(offsuit non-pair) = 3 *(13-1)/51 = 12/17). It is typical to abbreviate suited hands in hold 'em by affixing an "s" to the hand, as well as to abbreviate non-suited hands with an "o" (for offsuit). That is, :QQ represents any pair of queens, :KQ represents any king and queen, :AKo represents any ace and king of different suits, and :JTs represents any jack and ten of the same suit. There are 25 starting hands with a probability of winning at a 10-handed table of greater than 1/7.〔''No-Limit Texas Hold'em'' by Angel Largay〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Texas hold 'em starting hands」の詳細全文を読む スポンサード リンク
