Qg4 {This looks strange, but White's pressure on g7 lets him bend the rules about bringing out the queen too early.} 4... Qf6 { But this is a blunder. Black overestimates the strength of his check on f2.} 5. Nd5 Qxf2+ 6. Kd1 {Now Black has run out of checks but still has to defend against threats to both c7 and g7, as well as his queen getting trapped.} 6... Kf8 7. Nh3 Qd4 8. d3 Bb6 9. Rf1 {In the time it has taken Black to cover c7 and g7 White has developed three pieces, including his rook on the semi-open file leading to Black's king and he now has threats like 10.Rxf7+ Kxf7 11. Nxb6+ and 10.Nxb6 axb6 11.Rxf7+.} 9... Nd8 10. c3 Qc5 11. Ng5 h6 {The final err or, losing a tempo. He had to try 11...g6 or 11...h5, though White's attack would be strong then as well.} 12. Qh5 {While Black's check on f2 was easily answered. White's impending check on f7 will be followed by his whole army flooding into Black's kingside.} 1-0
