First-move advantage
In chess tournaments and matches, the frequency with which each player receives white and black is an important consideration. In matches, the players' colours in the first game are determined by drawing lots, and alternated thereafter. p11 In All-play-all round robin tournaments with an even number of players, each receives one extra white or black. The double-round robin tournament is considered to give the most reliable final standings, since each player receives the same number of whites and blacks, and plays both white and black against each opponent.p56
