Second, a player is selected and chooses the first-turn-player. If it is the first game of a match, one of the players is selected using a random method that is mutually agreeable. If it is not the first game of a match, the player who lost first in the previous game of the match is the selected player; or if the previous game ended in a draw, the selected player is the same as in the previous game. The select player then chooses any player to be the first-turn-player.
