42.Qxf7+? [After the text move, the endgame is completely hopeless for White. He should have activated his king.]

⚪️Karjakin,Sergey (2753)

🔸1-0

16.Nxb6!
A timely exchange in order to get the f2–pawn out the pin and exploit the awkward position of the opponent's bishop.

[16.Bb3!? △N×b6 16...Kg7 17.Nxb6 axb6 18.f3 Nxg3 19.hxg3! Bh5 20.exf5± △g4]

16...axb6 17.f3 Nxg3™ 18.hxg3?!
18.Qxg3! would be better: 18...Bh5 19.Qh3! △Q×h6 19...Qe8 20.exf5±

18...Bh5 19.exf5 Bf7 20.g4 Kg7?±
Harikrishna misses the opportunity to take back his pawn.
