Chess Daily News from Susan Polgar
Susan is right about Yifan. She’s good.
She’s also very lucky. N. Kostinseva missed a clear continuation and her time management was terrible. She only had 3 minutes on her clock to Yifan’s 26 minutes.
Yifan’s last move was not the best. She played Qg5-c1. But much stronger was either Rc1 or Rxb2. However I am not going to complain about success.
I see sets like this in a lot of photos. Why do they make the rooks so small and out of proportion to the other pieces?
A great game. Kosintseva relied only on a pin to protect her knight and Yifan punished her for it. What I’m wondering is why K. played 27. Qe5 instead of Qxh6 which builds some pressure.
32… Bd3 is in my eyes the greatest move in the game. Accepting the sacrifice with either cxd3 (..Rxc1#) or Qxd3 (..Qxd3) means pain. Declining means less pain, but still a lot. Kosintseva could have resigned immediately after Yihan played that move. It’s that good.
