1... e5 2. Ng1f3 Ng8f6 3. d4 exd4 4. e5 Nf6e4 5. Qd1xd4 d5 6. exd6 Ne4xd6 7. Bf1d3 Nb8c6 8. Qd4f4 g6 9. O-O Bf8g7
This is so far a book line of the Petrov. Equality.
10. Rf1e1 Bc8e6 11. Nf3g5
White plans to exchange on e6, leaving Black with an isolani. However, the plan proves to be fatally flawed.
11... O-O 12. Ng5xe6 fxe6 13. Qf4g3 Bg7d4
Black's energetic response shows the flaw immediately: Black now has a higher-value target than the isolated e6 pawn, namely White's f2 pawn.
14. Re1e2 Nd6f5 15. Qg3f3 Nf5e3 16. Qf3e4 Ne3d1
White's lack of development, and Black's superior mobility, make the game completely one-sided. White can no longer hold the f2 pawn or prevent the invasion of his position by the Black pieces.
17. Nb1d2 Nd1xf2 18. Re2xf2 Rf8xf2 19. Kg1h1 Nc6e5 20. Nd2f3 Ne5xd3 21. Qe4xd3 Bd4b6
This is a splendid diagonal for the bishop, as it strikes f2 and g1.
The alternative, ... QxQd8+, RxRd8; Bg5, Rd5 did not look any more promising. White cannot move the queen anywhere else, otherwise there are back-rank mate threats.
22... Qd8xd3 23. cxd3 Rf2xb2 24. d4
White's position is so shattered that it can hardly be improved. Nonetheless, White tries to block Black's powerful bishop.
24... Ra8f8 25. h3
Opening an escape square, in anticipation of an imminent double-rook assault.
25... Rf8f5 26. h4 Rf5b5
White can no longer avoid the exchange of rooks on the back rank and subsequent loss of the a2 pawn. Further resistance is futile. White resigned. 0-1
