11. Petrosian - Spassky, Round 10, Moscow, 1966
Tigran Petrosian was the greatest defensive player of the twentieth century. He played a prophylactic style he learned from reading the works of Nimzovich, but knew how to play tactically and often rounded off his victories with a tactical twist, as he does here.

    • The game is equal. A good plan for Black is to redeploy his poorly placed Knight at a5 to the kingside.

    15.f3 e4 16.Bb2 exf3

    • 16...Bxb2 17.Qxb2 exf3 18.Bxf3 Ne5 19.Qc2 bxc4 20.bxc4 remains equal.

    17.Bxf3 Bxb2 18.Qxb2 Ne5 19.Be2 f4

    • 19...bxc4 20.bxc4 Qg5 21.Kh1 f4 22.gxf4 Rxf4 23.Rg1 gives White the advantage in space and a slight initiative.


    • White should exchange Rooks and then develop his Knights.
    • If 20.Rxf4 Rxf4 21.gxf4 Ng6 22.Ne4 then:
      • 22...Nxf4 23.Ne3 Qe7 24.Bf3 Bh3 25.Kh1 Rf8 remains equal.
      • 22...Qe7!? 23.Nf6+ Kf8 24.Nh5 bxc4 25.bxc4 defends White's weak f-pawn and gives White the b-file.


    • The plan turns out to be faulty.
    • 20...Ng6 21.Qc3 then:
      • 21...Qe7 22.Bh5 Nxf4 23.Kh1 Nxh5 24.Rg1+ Ng7 25.Qxa5 remains equal and does something about the Knight on a5.
      • 21...bxc4 22.bxc4 Ra7 23.Ne3 Nxf4 24.Kh1 remains equal.

    WHITE: Tigran Petrosian
    Position after 20...Bc8h3


    • Spassky was probably expecting this reply, with which White sacrifices the exchange.
    • 21.Re1 Qh4 22.Nf2 Rxf4 23.Nxh3 Qxh3 gives Black a vicious attack.


    • Black takes the bait.
    • 21...Rxf4 22.Rxf4 Qg5+ then:
      • 23.Rg4! Nxg4 24.Nxg4 Bxg4 25.Bxg4 h5 26.Rf1! leaves White better because Black's Knight is still misplaced.
      • 23.Kh1 Qxf4 24.Rg1+ Ng6 25.Ng2 Bxg2+ 26.Rxg2 gives White a slight advantage owing to better piece placement.

    22.Rxf1 Ng6

    • It is now difficult to find a good continuation for Black.
    • 22...Nd7 23.cxb5 axb5 24.Bxb5 Rf7 25.Kh1 leaves White with a far more active game; Black has two inactive pieces on the queenside.


    • The Bishop is clearly headed for e6.
    • If 23.f5 Qg5+ 24.Ng4 then:
      • If 24...Rae8! then after 25.fxg6 Rxe2 26.gxh7+ Kxh7 27.Qb1+ Kg7 Black wins the Knight.
      • If 24...Ne5? then White wins after 25.Ne4! Qh4 26.Rf4 Qe1+ 27.Kg2 bxc4 28.Nxe5!! when White either delivers mate or wins signigificant material.


    • 23...h5 24.Be6+ Kh7 25.Nf5 Rxf5 26.Bxf5 gets White the exchange back with a powerful position.


    • 24.Ne4 Qh4 25.Rxf4 Rxf4 26.Be6+ Rf7 27.Nxd6 wins for White.

    24...Rxf4 25.Be6+! Rf7

    • 25...Kf8 26.Qh8+ Ke7 27.Qxh7+ Ke8 28.Qg6+ Ke7 29.Qg5+ wins for White.

    26.Ne4 Qh4 27.Nxd6 Qg5+

    • Black survives a little longer after 27...Raa7 when:
      • If 28.Bxf7+ Rxf7 29.Qg2+ Kf8 30.Nxf7 then:
        • If 30...Qe1+ 31.Nf1 Kxf7 32.Qc2 then after after 33.Qxh7+ White has with two passed pawns; Black's Knight is still poorly placed.
        • 30...Kxf7 31.cxb5 Qe1+ 32.Nf1 axb5 33.Qc2 c4 34.Qxh7+ is an easy win for White.
      • 28.Nxf7 Rxf7 29.Bxf7+ Kxf7 30.Qf2+ Qf6 31.Qe2 leaves White with an extra pawn and Black with an offsided Knight.

    28.Kh1 Raa7 29.Bxf7+ Rxf7

    WHITE: Tigran Petrosian
    Position after 29...Ra7f7:B

    30.Qh8+!! 1-0

    • White wins a piece.
    • If 30...Kxh8 then after 31.Nxf7+ Kg7 32.Nxg5 it's time to turn out the lights.
    • Boris Vasilyevich resigns.
