The time control for the four games is 40 moves in 90 minutes followed by 30 minutes and a 30-second increment as of move one. Draws cannot be offered before move 30, and if the match ends in a 2-2 tie, a blitz tiebreak will take place at the rate of 5 minutes plus 3 seconds. If even this is tied, then a special super-bitz game will be used to decide the winner. This is not an Armageddon game. Instead, a single blitz game at the rate of 5 minutes plus 2 seconds will be played with the following condition: if it ends in a draw, the clock times are left as they are, the colors are reversed, and the players start a new game with those times left. This will continue until the tie is broken.

After the game, Hou Yifan commented, “My play in this game was just not good. I was a little bit anxious and impetuous. I tried to complicate the game but Vassily played very accurately and I never had any winning chances.”
