🔸Russian Rapid Team Championship 2018
🔸Round 4
⚪️Nepomniachtchi,Ian (2759)
⚫️Alekseenko,Kirill (2639)
🔸0-1

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.
67.Kf2 Nxd3+ 68.Ke3 Bxf5 69.gxf5 Kf6 70.Rg6+ Kxf5 71.Rxd6 Ne5 72.Rd8 Rc3+ 73.Ke2 Rxc4 74.Ke3 Re4+ 75.Kd2 Rd4+ 76.Ke3 Nc4+ 77.Kf3 Ke5 0–1
