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.
Game four
Vassily Ivanchuk was in excellent form throughout the match
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.”
