Congratulations to GM Hikaru Nakamura! 👏😃👏
It was a thrilling match and often competitive, but Nakamura was just too strong in this #speedchess format.

66.Kf1?
Nepomniachtchi made a blunder which cost him the game.
He could have obtained equality through the following continuation:
66.Ke1= Nxd3+ (66...Bxf5 67.Bxf5 Rxc4 68.Re7+ Kxd5 69.g5= with the idea of g6) 67.Kd2 Rxc4 68.Kxd3 Rxg4 69.Rxd7 Kxf5 70.Rxd6=
66...Rc1+–+
Black wins the bishop with check.
