27... Qc7
36-year-old Spanish GM could have grabbed an exchange with the following surprising continuation:
27... Nf3! 28. Qxf3 Re5 29. Re4!
A) 29. Rxe5 Qxf3+ -+
B) 29. Qxb7 Rxe1+ 30. Kg2 Rxb7 -+
C) 29... Rxe4 30. dxe4 Rxd2-+

28... Rfe8??
Vallejo's blunder. His bishop is caught in a very annoying pin.

25.b4!?
White intends to place his queen on the a1-h8 diagonal. However, 25.Qc2 and then b4 is better.
25...Qe5
Now, 26.Ng3 is clearly impossible due to the pin.
26.Qc2 Qe6 27.Rd4 Be5 =

Vallejo needed to win. He tried to provoke his opponent to weaken the e3-pawn, But his gamble failed due to the trapping his knight on h3.

14.Kb1!
Planning to drop the bishop back to c1, to cover b2 as well as keeping the bishop out of the clutches of a knight on c4. Again, though, was this necessary?
14...Nc4 15.Bc1 Qb6 16.Qh4?!
White can play 16.Qxb6 Rxb6 17.h4 but he didn't want to exchange queens. In this position White no longer has the plan of h4-h5, but he had in mind the idea of pushing the f-pawn and possibly playing Rd3-Rh3.
16...a5 17.f5
Giving away the e5-square, but this negative had to be weighed up against the positive threat of playing f6 and having this pawn as a thorn in Black's side.

To support the Ng5 sortie and to meet ...Bxg5 with hxg5 opening the h-file for the rook on h1.
15...Qc7
15...h6 tries to prevent Ng5, but... 16.Ng5! (anyway!) 16...hxg5 17.hxg5 g6 18.Rh6 Kg7 (or 18...Bxg2 19.Rxg6+ fxg6 20.Qxg6+ Kh8 21.Qh6+ Kg8 22.g6 Rf7 23.gxf7+ Kxf7 24.e6+ Kg8 25.Rg1
; Black's extra pieces are on a8 and b8!) 19.Rdh1 Rg8 20.e6 and White wins.
16.Ng5 g6 17.Bd5 dxe5 18.Nxh7! Kxh7 19.h5
