(1) Karjakin,Sergey - Caruana,Fabiano
The Candidates Moscow, 2016
[GM Lubomir Kavalek/The Huffington Post]

36...Re4? It is hard to blame Caruana for this move, but he is forcing Karjakin to make the winning combination. [Instead, he could have given up the pawn 36...Bf3 37.Rxb4 Qc7 with a playable game.]

37.Rxd5!
Without this rook sacrifice, White would be worse.

37...exd5 38.Qxd5
Threatening 39.Qd7 mate.

38...Qc7
Caruana did not have much time and his move loses by force. [The only way to stay in the game was 38...Rd4 39.Qxd4 Qxd4 40.Rxd4 Rb8 White is a healthy pawn up and Black can't win.]

39.Qf5! Rf7
[After 39...Qc6 40.Qh7+ Ke8 41.Qxh5+ Ke7 42.Bd5+- wins.]

40.Bxf7 Qe5
Playing into mate.

41.Rd7+ Kf8 42.Rd8+
[42.Rd8+ Kxf7 (42...Kg7 43.Qg6# ; 42...Ke7 43.Qd7# ) 43.Qh7+ Ke6 44.Qd7# ] 1-0
