 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.

 in poker, many of these hands are identical in value before the flop. For example, and are identical, because each is a hand consisting of an ace and a jack of the same suit. There are 169 nonequivalent starting hands in hold 'em (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)

). There are 25 starting hands with a probability of winning at a ten-handed table of greater than 1/7. 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.

 assigned each hand to a group, and proposed all hands in the group could normally be played similarly. Stronger starting hands are identified by a lower number. Hands without a number are the weakest starting hands. As a general rule, books on Texas hold'em present hand strengths on the assumption of a nine or ten person table. The table below illustrates these groupings with those corresponding to off-suit cards below the main diagonal and those for cards of the same suit above.

Chen formula

The "Chen Formula" is a way to compute the "power ratings" of starting hands that was originally developed by Bill Chen.
Highest Card

Based on the highest card, assign points as follows:
Ace = 10 points, K = 8 points, Q = 7 points, J = 6 points.
10 through 2, half of face value (10 = 5 points, 9 = 4.5 points, etc.)
Pairs

For pairs, multiply the points by 2 (AA 20, KK = 16, etc.), with a minimum of 5 points for any pair. 55 is given an extra point (=6).
Closeness

Subtract 1 point for 1 gappers (AQ, J9)
2 points for 2 gappers (J8, AJ).
4 points for 3 gappers (J7, 73).
5 points for larger gappers, including A2 A3 A4

Add an extra point if connected or 1-gap and your highest card is lower than Q (since you then can make all higher straights)
