Notes by John Collins.

1.d4 d5 2.Nf3 Nf6 3.c4 c6 4.Nc3 dxc4 5.a4 Nd5
I have played Janos many times, and I often cannot guess his next move in the opening. Perhaps because of this he often gets good positions against me - not this time! I was surprised to find that this move has been played before, by another Hungarian called Polgar (not one of the famous sisters).

6.e4 Nxc3 7.bxc3 Be6
This was also played by the mysterious Polgar; White continued Rb1 and eventually won.

8.Ng5
This looks crude, but the idea is to advance the f-pawn immediately.

8...Qd7 9.f4 Bg4 10.Be2 Bxe2 11.Qxe2 b5 12.0-0 h6 13.Nf3 Qg4?
This is a terrible move; he has to move the Q again to develop his N, but this loses a lot of time, and the extra pawn.

14.Qb2 Qd7 15.Ne5 Qb7 16.Nxc4 e6 17.f5!
Now Black can never get safely castled.

17...exf5 18.Rxf5 Nd7 19.axb5 c5 20.Qf2 Qxb5
[If Black plays 20...Qxe4 then 21.Ba3 looks winning. ]

21.Ne5 Nf6
[If Black plays 21...Nxe5 then 22.Rxe5+ followed by Ba3.]

22.Qa2 Qb7 23.Rb1 Qc7 24.Qa4+ Kd8 25.Bf4
At last my Q-side is developed! Now simplification leads to a clear win.

25...Bd6 26.Nxf7+ Qxf7 27.Bxd6 cxd4 28.Qa5+
Black loses his Q, is mated (or both). [Fritz gives 28.Qa5+ Ke8 29.Re5+ Qe6 30.Rxe6+ Kf7 31.Rb7+ Kg8 32.Qc7 Nh5 33.Qf7+ Kh7 34.Bf4 Nxf4 35.Qxg7# as the longest mate.] 1-0
