Spassky–Petrosian, World Championship Game 19 — Chess Library

Boris Spassky’s win in Game 19 of the 1969 World Championship is a direct Sicilian attack against Tigran Petrosian’s king. White builds methodically, sacrifices when the files open and finishes before Black can organize a defense.

Lesson

White to move. Main line: 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 Nbd7 7. Bc4 Qa5 8. Qd2 h6 9. Bxf6 Nxf6 10. O-O-O e6 11. Rhe1 Be7 12. f4 O-O 13. Bb3 Re8 14. Kb1 Bf8 15. g4 Nxg4 16. Qg2 Nf6 17. Rg1 Bd7 18. f5 Kh8 19. Rdf1 Qd8 20. fxe6 fxe6 21. e5 dxe5 22. Ne4 Nh5 23. Qg6 exd4 24. Ng5

Spassky castles queenside and brings both rooks toward the kingside. The moves f4, g4 and f5 look aggressive, but the attack is supported by development and control of the center rather than hope.

After 15.g4 Nxg4, White gains open lines and tempo against the knight. The rook reaches g1, the second rook comes to f1, and 20.fxe6 opens the f-file while Black’s queen and queenside pieces remain distant.

The concluding 22.Ne4 Nh5 23.Qg6 exd4 24.Ng5 creates unavoidable threats around h7 and f7. The game illustrates a sound pawn storm: pieces arrive first, pawn exchanges open the correct files, and every sacrifice has a concrete follow-up.
