54. Re7??
A strange blunder. Fabiano has completely forgotten that the e3-knight is pinned. ☺️

17...Qd7!
Black vacates the d6-square for the knight and tries to defend against the threat of Qa4. 17...Qd7 prepares ...Nb7-d6. The game continuation avoids 17...Rae8? 18 Bd2 and White is better because he can exchange on a5, destroying Black's queenside, and if 18...Nb7 then 19 Qa4 is winning.
18.Ng3 Rae8! 19.Bd2 Nb7 20.Ne4 Nd6 21.Nxd6 Qxd6 22.Qa4?!
Boris: My opponent evaluated the position too optimistically and decided to take the a7 pawn. However, the queen on a7 will be excluded from the game, allowing Black a strong and sudden kingside counterattack.
22...Bc8 23.Qxa7 Be5! 24.h3?! Bd4!
After provoking the weakness on h3, Black is ready to sacrifice on h3 and give check on g3. In order to accomplish this, I need to pin the f2-pawn.

14.Qa4!
By threatening to increase the pressure with 15 Qb5, White forces Black to take on d5.

Boris: Now that I have forced Black to play his knight back to b8, I hope to take advantage of its poor placement.
