In poker, a straight is a pair of cards. If you have an ace and a seven in the hole, you have the top pair. However, if you have a 3-4-7 flop, you have an overpair, which is a pair with more than seven cards. It is possible to make a backdoor flush by hitting the required cards on the turn and river.
There are usually five to seven players at a poker table. A player who has the highest hand wins. If the other players are all out, the winning player collects the pot. The pot is the total of bets made by all players during the hand. If no one has a winning hand, the pot is split evenly between the remaining players.
A player in the first-to-act position is seated to the left of the button and the big blind. This position remains for subsequent betting rounds. If a player has a high hand, the odd chip goes to the player with the highest hand of that suit. The other player with the lowest hand of that suit loses the chip.
A pair is a set of two cards of equal rank. Three other cards may not be a match. Pairs are often compared using two sets. The highest pair wins. For example, J-J-2-2-4 beats 10-10-9-9-8, while a pair of jacks beat a pair of tens.
