 FEN: r3kbnr/p3p2p/4b1p1/1p1p4/8/4P3/PPPP1PPP/RNB1KB1R |
This is one of the standard positions from this opening. White have a material advantage and black seeks to find counterplay down the f-file.

After this move Sordid was brought out of book.
As briefly explained in Tactical Ideas black's main plan here involves sacrifices in order to open the f-file for a rook invasion.
9.f4?! Placing the f-pawn here, where it's susceptible to sacrifices from the bishop on h6 isn't really advisable
9…0-0 10.Bd3 10.Bg2 seems better to me, as it prevents 10... Ne4: 10…Ne4? 11.Nxd5 Bxf4 12.Bf3+-
10…Ne4! 11.0-0 Forced move. 11.Nxd5 and 11.Bxe4 both lose to 11…Bxf4 with a subsequent rook invasion.
11…Nxd2 12.f5!
 FEN: r4rk1/p3p2p/4b1pb/1p1p1P2/6P1/4P3/PPP4P/R4RK1 |
This strong advance gives white counter play and in fact seems to force a draw,IF white follows up correctly…

After this sequence of forcing moves an endgame has been reached. White has a common situation of having a pawn against a bishop. From the Endgames section you can see that unless black can create a passed pawn white can draw simply by placing his pawns on the opposite colour to black's bishop.
However with the next move white began to go astray…
17.g5?! Not losing yet but certainly fixing a pawn on the wrong colour is a step backwards for white. One way to draw would have been 17.e4! e.g. 17…d4 18.b3 a5 19.h3 was an unassailable position
17…Bg7 18.e4 Kg8
 FEN: 6k1/p5bp/6p1/1p1p2P1/4P3/8/PPP4P/6K1 |
Now that white has locked one of his pawns onto a dark square black will block the white e-pawn with his king before contemplating any bishop sacrifices.
19.b4?? After this move white has no chances to draw. 19.e5 appears to hold for white, e.g: 19.e5 Kf7 (19…Kf8 20.b3! Ke7 21.e6 comes to the same thing) 20.e6 Ke7 21.b3!
 FEN: 8/p3k1bp/4P1p1/1p1p2P1/8/1P6/P1P4P/6K1 |
Here white can hold the draw, as black can only sacrifice the bishop on g5 when white will be able to blockade black's passed pawn further from the queening square than black has blocked white's.
19…d4 20.h3 White should really play 20.e5 now, pushing his passed pawn as far as possible, although it's too late to make a difference now.
20…Kf7 21.Kg2 Ke6 22.e5 Bf8

 FEN: 5b2/7p/4k1p1/P3P1P1/8/1p5P/6K1/8 |
Black doesn't even need his security move, Bc5, as his pawn is faster
27.Kf3 b2 28.Ke4 b1Q+ 29.Kd5 Qe4!

Creating a path for the king. Rest doesn't require any comments
30.Kd6 Kf5 31.Ke6 Kf4 32.a6 Ke3 33.Kf7 Qf5+ 34.Kg8 Qf7+ 35.Kh8 Qg8# 0-1
Good endgame from black, while white didn't know what striked him until it was too late.
