A tournament round in which a player does not have a game, usually because there are an odd number of players. A bye is normally scored as a win (1 point), although in some tournaments a player is permitted to choose to take a bye (usually in the first or last round) and score it as a draw (½ point).

What you get when you can’t play a round, but are still continuing to play in the tournament. Byes don’t count for ratings, but can be either 0 points, ½ point, or 1 point (in case you want to play, but are the odd person available).
