1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.0-0
In Fischer’s games one can sometimes see the
influence of Morphy and Steinitz, but in the given instance he is the
successor of Lasker, who played this variation just as masterfully
(although using the old 5.Nc3 or 5.d4).
5...f6 6.d4 exd4 7.Nxd4 Ne7 8.Be3 Ng6 9.Nd2 Bd6
10.Nc4 0-0 11.Qd3 Ne5 12.Nxe5 Bxe5 13.f4 Bd6 14.f5
This game is reminiscent of the famous Lasker –
Capablanca game at St. Petersburg 1914. White gives himself a backward
pawn but gains space on the kingside to compensate. The idea is
very double-edged.
14...Qe7 15.Bf4
White’s plan includes the exchange of the
dark-squared bishops followed by e4-e5 or even g2-g4-g5. As usual
in such positions, Fischer acts with iron consistency.
15...Bxf4 16.Rxf4 Bd7 17.Re1 Qc5 18.c3 Rae8 19.g4
Qd6 20.Qg3 Re7
Black could have considered 20...c5 21.Nf3 Qb6 (but
not 21...Bc6 22.g5! with a growing initiative for White).
21.Nf3 c5
Now Fischer sets about consistently converting his
extra pawn on the kingside.
22.e5 fxe5 23.Rfe4 Bc6 24.Rxe5 Rfe8 25.Rxe7 Rxe7
26.Ne5 h6 27.h4
27…Bd7
Unzicker has been holding on without making any
aggressive moves and just when he must strike out to save his life
(27...Qd5 28.Nxc6 Rxe1+ 29.Qxe1 Qxc6 30.Qe3 Qd5) he finds the strange
manoeuvre ... Bc6-d7-c8.
28.Qf4 Qf6 29.Re2 Bc8 30.Qc4+ Kh7 31.Ng6
Black’s king is trapped and his bishop is bad because
of the pawn structure. Also, he never gets time to capture on g4.
31...Rxe2 32.Qxe2
32…Bd7
Like many of Fischer’s other opponents, Unzicker
cracks under the prolonged pressure. After 32...Qd6! it is
doubtful whether White could have converted his slight positional
advantage, on account of the open position of his king: 33.Ne7 Qg3+
34.Kf1 Bd7 35.Qe4 Bb5+ 36.c4 Qh3+ with perpetual check, or 33.Qe8 Qg3+
34.Kf1 Qd3+! 35.Kg2 (35.Qe2? Bxf5!) 35...Qd2+.
33.Qe7 Qxe7 34.Nxe7
A rare instance, when Fischer plays not with a
bishop, but a knight against a bishop. And his knight completely
dominates, keeping the black king imprisoned.
34...g5 35.hxg5 hxg5 36.Nd5 Bc6 37.Nxc7 Bf3 38.Ne8
Kh6 39.Nf6 Kg7 40.Kf2 Bd1 41.Nd7
41...Bxg4 42.f6+ Kg6 43.f7 Kxf7 44.Ne5+ wins the
bishop.
41...c4 42.Kg3 1-0 Black resigns
