In the knockout stage, each encounter will be decided over two days. On day 1, there will be four rapid games, and if the match ends 2-2 it will simply be a draw (there doesn’t have to be a winner). On day 2, another 4-game match will be held. If both matches are drawn, or the players have traded wins, then shortly after the second match there will be a playoff: two blitz games followed, if needed, by Armageddon.
The time control is 15 minutes for all moves, with a 10-second increment from move 1. No draw offers are allowed before move 40.
