On the top boards there have been a lot of draws throughout the event, and that has continued in round 4. Alireza Firouzja gave up his first half point in the event, but remained in clear first as none of the 2.5-pointers coming into the round won their games, either. Some 2-pointers won, so now there are 11 players nipping at Firouzja's heels. Seven rounds remain, so it's too soon to get too excited.
I've annotated a couple of games from round 4, plus the game Predke-Yakubboev from round 2, mentioned by a couple of readers in the comments. Enjoy!
