While there was no tie for first place, such a situation would have been addressed as follows:
If two players tie for first a two-game 10+2 rapid match will take place. If there remains a tie, a single armageddon game will occur.
If three or four players tie for first a single round-robin in the 10+2 rapid time control will take place
If two players remain tied, they contest a two-game 3+2 blitz match. If the tie persists, an armageddon game decides the winner.
If three or more players remain tied, they contest a 3+2 round-robin.
If more than four players tie for first players will contest a 3+2 round-robin. If the round-robin ends in a tie, a series of armageddon games decide the winner.[2]
