1. d4 Nf6 2. Nf3 e6 3. g3 b6 4. Bg2 Bb7 5. c4 Be7 6. Nc3 O-O 7. Qc2 c5 8. d5
exd5 9. Ng5 { White exploits the pin on the h1-a8 diagonal to maintain his
outpost on d5.} 9... Nc6 {Black gives up on fighting for d5. He should play
9...g6 to neutralize the mate threat on h7.} 10. Nxd5 g6 11. Qd2 {Black has
neutralized the b1-h7 diagonal, so White prepares to attack the new weakness
on h6 with his queen.} 11... Nxd5 {Black brings White's g2 bishop to a strong
attacking square. He should have played 11...Re8 to cover the h6 square by
12...Bf8.} 12. Bxd5 Rb8 {Black unpins his c6 knight, but this costs a fatal
tempo. He had to simplify. 12...Bxg5 13.Qxg5 Qxg5 14.Bxg5 White has a great
endgame because of the two bishops and Black's backward pawn on d7.} 13. Nxh7
Re8 {White gets a winning attack after 13...Kxh7 14.Qh6+ Kg8 15.Qxg6+ Kh8
16.Qh6+ Kg8 17.Be4 f5 18.Bd5+ Rf7 19.Qg6+ Kh8 20.Bxf7} 14. Qh6 Ne5 15. Ng5
Bxg5 16. Bxg5 Qxg5 { 16...Qc7 17.Bf6} 17. Qxg5 Bxd5 18. O-O {White can't take
the bishop.} 18... Bxc4 19. f4 {Not only is Black down a queen for only two
minor pieces, but White still has an attack. So Black gave up.} 1-0
