O-O d6 7. d4 exd4 8. cxd4 Bb6 {For the sacrificed pawn White has obtained a lead in development.} 9. Nc3 {The development of the queen knight in this position was a Morphy specialty. 9. d5 was favored by another great attacking player: Adolf Anderssen.} 9... Qf6 {Black's idea is to put pressure on the White d-pawn. However, this is a mistake since the Black queen will be subject to attack on f6.} 10. Nd5 Qg6 { 10...Qd8 Admitting that his last move was a mistake was Black's best move.} 11. Nf4 Qf6 12. e5 {White is able to open up the position for the attack due to the unfortunate position of the Black queen.} 12... dxe5 13. dxe5 Qf5 14. e6 f6 {Black desperately tries to keep the e-file closed. 14...fxe6 15.Nxe6 Bxe6 16. Bxe6 Qxe6 17.Re1 Black's queen is been trapped due to the pin on the e- file.} 15. Nh4 Qc5 16.

Qh5+ {Black's backward development with his king remaining in the center gives White a winning attack.} 23... Kd8 { 23...g6 would allow White a winning combination.} 24. Rad1 {Black resigned because he has no good defense to the discovered check on the d-file.} 1-0
