Black quickly enters a typical Sicilian queenless game and uses the central pawns, good king position(from ..Ke7) to get good play.

There is nothing to fear in the queenless game.[Yip]
16.Bxe2 Nf6 17.Be1 Ke7 Diagram 1
The king is well placed for the ending phase.[Yip]
18.h3 g5
Securing the strong Ne5.[Yip]
19.Nd4 Bd7 20.Kb1 b5
Gaining useful queenside space. The queenless phase is characterized by purposeful building moves rather than tactical play.[Yip]
21.a3 Rac8 22.f3 Nc4
The knight finds a more active location.[Yip]
23.Rd3
Now black is slightly better.[Yip] [23.Bxc4 Chopping off the active knight is a better defence.[Yip] 23...bxc4= [Yip]]
23...Rc7 24.h4
Trying to undermine the kingside pawns.[Yip]
24...g4!? 25.f4
[25.fxg4 Ne5 26.g5!? At least keeps the g-file closed.[Yip] (26.Rd1 Nfxg4 Regains the pawn with excellent prospects on the g-file.[Yip]) 26...hxg5 (26...Nxd3 27.gxf6+ Kxf6 28.Rf1+ Kg7 29.Nf5+ exf5 30.Bxd3 fxe4 31.Nxe4 d5 32.Nf6 Be6³ Is also slightly better for black but white has gained some activity for the exchange.[Yip]) 27.Rd1 g4³ Is good for black.[Yip]]
25...Rb8 26.Nd1?
Now white is suffering.[Yip] [26.Rd1³ Is a better defence.[Yip]]
26...Nxe4 27.Bxg4 Rg8
Now there is serious pressure on the g-file.[Yip]
[27...Nc5 Is a strong alternative.[Yip] 28.Rc3 f5 29.Bh3 Ne4 30.Rd3 Rg8µ Black has a clear edge with strong play on the g-file.[Yip]]
28.Bf3 f5 Diagram 2
Black clearly dominates the ending with the centralized Ne4 and pressure on the g-file.[Yip]
[28...Nxg3 Winning the g-pawn immediately is stronger.[Yip] 29.Rg1 Bxd4! The key move. Now when Rxd4 is played, ...Nf5 will gain a tempo.[Yip] 30.Rxd4 Nf5 31.Rxg8 Nxd4 32.Be4 Rc8 33.Rxc8 Bxc8µ Black is clearly better with an extra pawn.[Yip]]
