In Go black goes first, but because that is greatly advantageous to capturing territory, those who draw black cede six and a half "eyes" to white (an eye is a unoccupied spot on the grid surrounded by one's stones). The players change colors every game.
圍棋賽規定「黑先行」，但因先行者較具佈局優勢，因此在最後計算時，持黑棋者得禮讓白棋 6 目半（棋盤上橫軸和縱軸的交點稱為「目」），並且必須在雙方第二場比賽時改執白棋。
