As mentioned in a previous rules tip most matches are played until a single player wins two games. (There are a few exception in finals matches at large events.) But what happens in a Swiss event when neither player has won two games when time is called?
When time is called the current turn will be completed and then an additional five turns are taken. If it is player A’s turn when time is called, that turn will be finished, then B will take a turn, A will take one, B will take one, A will take his final turn, and B his final turn.* If after those additional five turns a player has not won two games then a few things can happen.
If neither player has more wins than the other, then the match is a draw. For example, if this is still game one and neither player has won a game, then the match will be a draw. This can also happen if this is game three and both players have won a game and this third game is unfinished. While uncommon it can also happen in situations where a previous game ended in a draw because both players lost at the same time.
In some cases there can be a winner after the extra turns are taken and that game does not end in a winner. If it is game two when time is called, and this game is not completed then the player with one win will win the match.
*This order can be disrupted if effects that cause players to take extra turns are generated in the extra turns. There can only be five additional turns after time is called. If a player generated an extra turn, then he or she will change the order and number of extra turns that a player takes.
