The rules of Poker
No-limit Texas hold'em for two to eight. Two cards each, face down; then five on the table, shared by everybody: the flop of three, the turn and the river.
The two players after the dealer put in the small and big blinds, and the blinds move one seat a hand. In each of the four rounds of betting, fold, check, call, bet or raise: a raise adds at least what the last one added, and you may go all in at any time.
At the showdown the best five cards of your seven take the pot, best first: straight flush, four of a kind, full house, flush, straight, three of a kind, two pair, pair, high card. A-2-3-4-5 is the lowest straight, and suits never break a tie. A player all in for less wins only the pot they could match; the rest goes to side pots.
