[Event "Varna Olympiad"] [Site "?"] [Round "0"] [White "Fischer"] [Black "Najdorf"] [Result "1-0"] [ECO "B90"] [Opening "Sicilian: Najdorf"] 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. h3 b5 7. Nd5 Bb7 { Black should probably take the pawn. White gets an initiative after 8.Qf3, but Black seems to hold. Now Najdorf's king has nowhere to hide.} 8. Nxf6+ gxf6 9. c4 {The kingside is already unsafe, and no Fischer goes to work on the center and the queenside.} 9... bxc4 10. Bxc4 Bxe4 11. O-O d5 12. Re1 {No rest for the weary. Black's last move is shown to have serious drawbacks-- he can't get his bishop back to b7, and his dark squares look weak.} 12... e5 13. Qa4+ Nd7 14. Rxe4 {This sacrifice reopens the a2-g8 diagonal and gives White control of all the light squares in the center.} 14... dxe4 15. Nf5 Bc5 16. Ng7+ { Typically, Fischer's play is ruthlessly accurate. The text allows White to finish his development with the Black king a sitting duck in the center.} 16... Ke7 17. Nf5+ Ke8 18. Be3 {Again, simple but deadly-Black must either lose time retreating the bishop or give up d6. If 18...Qb6, 19.Bxf7+.} 18... Bxe3 19. fxe3 Qb6 20. Rd1 Ra7 21. Rd6 Qd8 22. Qb3 {Now if Black could only castle there would be some hope, but White's 16th move ruled that out.} 22... Qc7 23. Bxf7+ Kd8 24. Be6 {Black is helpless-if he tries 24...Qc1+, after 25.Rd1 he has no way to cover b6 and b8 without giving up d7.} 1-0
