Nc3 Nc6 6. Nf3 Bg4 7. cxd5 Nxd5 8. Qb3 Bxf3 9. gxf3 e6 10. Qxb7 Nxd4 11. Bb5+ Nxb5 12. Qc6+ Ke7 13. Qxb5 Nxc3 { 13...Qd7 14.Nxd5+ Qxd5 and Black has nothing to worry about.} 14. bxc3 Qd7 { Black should have created some space for the king with 14...f6.} 15. Rb1 Rd8 { Another mistake. The a-pawn needs the support of the rook.} 16. Be3 Qxb5 17. Rxb5 Rd7 18. Ke2 { 18.Ra5 Rb7 19.Rxa7 Rxa7 20.Bxa7 Kd7 21.Kd2 Bd6 with the threat of Ra8.} 18... f6 19. Rd1 Rxd1 20. Kxd1 Kd7 21. Rb8 { The threat is Bc5, exploiting the pin on the back rank.} 21... Kc6 22. Bxa7 g5 {The only way Black can get his pieces into play is by moving the bishop to g7. } 23. a4 Bg7 24. Rb6+ Kd5 25. Rb7 Bf8 26. Rb8 Bg7 27. Rb5+ Kc6 28. Rb6+ Kd5 { It is not clear why Fischer repeated the position. Probably he had not worked out the sinning moves yet.} 29. a5 f5 30. Bb8 Rc8 31. a6 Rxc3 32. Rb5+ Kc4 33. Rb7 Bd4 34. Rc7+ Kd3 35. Rxc3+ Kxc3 {It looks as though Black is about to enter a long period of suffering after 36.a7. But then Black will sacrifice the bishop for the pawn. There is a better move. Do you see it?} 36. Be5 1-0
