King’s Gambit Accepted C37

1. e4 e5 2. f4 exf4 3. Nf3 g5 4. Bc4 g4 5. 0-0. The Muzio Gambit. 5. ... gxf3 6. Qxf3 Qe7 7. d4 Nc6 8. Qxf4. For 8. c3 Ne5! see Dubois – Anderssen, London 1862. 8. ... Nh6? 8. ... Nxd4 9. Bxf7+ Kd8 10. Nc3 c6 11. Qf2 is unclear but quite promising for White, Anderssen – Neumann, Berlin 1864, match game 1. The best is probably 8. ... Bh6! 9. Qxf7+ Qxf7 10. Bxf7+ Kd8 11. c3 Bxc1 12. Rxc1 Nh6 which seems to leave White with insufficient compensation for the sacrificed Knight, Schlechter – Chigorin, Vienna 1903. 9. Nc3 Nxd4 10. Nd5 Ne6 11. Qe5 Bg7 12. Nxc7+ Kd8. On 12. ... Kf8?? 13. Bxh6 wins outright. 13. Nxe6+ fxe6 14. Qb5? One would have expected 14. Qh5. 14. ... Ng4?? Had Black played 14. ... Nf7, the brave Serafino would have been in serious trouble. Now it’s all in its place: 15. Bg5 Bf6 16. Rxf6 Nxf6 17. Rf1 Rf8 18. e5 Ke8 19. Bxf6 Qf7 20. Qc5 d5 21. Bb5+ Bd7 22. Bh4 Qg7
