1. e4 e5 2. Bc4 Ne7? This move loses at least a pawn. 3. Qh5 Ng6?! Black must play 3....d5 4.exd5 Qd6, though White is up a pawn with a strong attack after 5.Nc3. 4. Nf3 f6? Intended to protect the e-pawn while preventing 5.Ng5, this move allows an even more devatating attack along the weakened h5-e8 diagonal. A better try was 4....d6 5.Ng5 Be6 6.Nxe6 fxe6 7.Bxe6, though White has a winning advantage with the two bishops, an extra pawn, and control of the white squares. 5. Nh4! b5?! Desperation. The pin along the h5-e8 diagonal combined with the pin on the h-pawn "defending" the Knight at g6 leads to an immediate loss of material for Black. The move b5, though, actually allows White to win the Rook at a8 rather than the one at h8! 6. Nxg6 hxg6 7. Qxg6+ Ke7 8. Qf7+ Kd6 9. Qd5+ Ke7 10. Qxa8 Nc6 Black is lost. If 10....bxc4 11.Qxb8. Black now attempts to trap White's Queen but with no success. The rest is easily winning. 11. Bxb5 Nb4 12. Na3 c6 13. c3 Qc7 14. cxb4 Bb7 15. Qxa7 cxb5 16. Qc5+ Qxc5 17. bxc5 Kd8 18. d3 1-0
