Match play
Match play is a scoring system for golf in which a player, or team, earns a point for each hole in which they have bested their opponents; this is as opposed to stroke play, in which the total number of strokes is counted over one or more rounds of 18 holes. In professional golf, a small number of notable tournaments use the match play scoring system.
Scoring system
Unlike stroke play, in which the unit of scoring is the total number of strokes taken over one or more rounds of golf, match play scoring consists of individual holes won, halved or lost. On each hole, the most that can be gained is one point. Golfers play as normal, counting the strokes taken on a given hole. The golfer with the lowest score on a given hole receives one point. If the golfers tie, then the hole is halved. For example, in an 18-hole match, the first hole is a par-4 and Player A scores a 3 (birdie) and Player B scores a 4 (par); Player A is now 1-up with 17 to play. In the same match on the second hole, a par-5, Player A takes 8 strokes and Player B takes 5 (par); Player B wins the hole and the match is now "all square" with 16 to play. On the third hole, a par-3, both players take 3 strokes and the match is all square with 15 holes to play. Once a player is "up" more holes than there are holes remaining to play the match is over. For example, if after 12 holes Player A is 7-up with six left to play, Player A is said to have won the match "7 and 6".
