dfcx: I also went with 14.Nb5.
According to the engine, black's best defense against Nb5 is 14.Nb5 (+3.50)
14...Bxf4
15.Nxc7 Rxd1+

With

Feb-13-18 A Kovchan vs A Volokitin, 2015 
|
dfcx: 31...? black to move would be a great puzzle for Wednesday or Thursday. According to Mr. Stockfish, white went down after 29.h3? (-2.89)
white would have kept himself in the game with 29.Kf1 (-0.45) 31.Rxf4?? (-8.30) sealed his fate. |

|
dfcx: <Walter Glattke: Better for White also were 19.g3 or 19.Ng6 Nxg6 20.Qxg6 Be6 21.Bxe6, but not good as 19.Qh7+.> After 19.g3 or 19.Ng6, 19...Qxc4+ and black is suddenly alive. |

Dec-16-17 Navara vs Z Sturua, 2016 
|
dfcx: Realizing
20.Re1? Nf2
21.Rxe7 Nxd3
22.Rxe8+ Rxe8
loses a piece for white, the solution comes up naturally. 20.Nxg6! fxg6
21.Re1 wins back the knight since 21...Nf2 is now met with 22.Qxg6+ White will be up a pawn and also open the g file for future attacks. |
