Petrov's Defense

  • 1. e4
    White moonbus, Black lazza, initial ratings within ten points. Notes by moonbus.
    • 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.
              • 22. Bc1g5
                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
