1.d4 Nf6 2.c4 g6 {Kasparov starts off as if he wants to play the King's 
Indian Defence.} 3.g3 Bg7 4.Bg2 c5 {Challenging White in the centre.} 5.d5
d6 6.Nc3 O-O 7.Nf3 e6 {But now play transposes into the Modern Benoni, an 
opening ideally suited to Kasparov's uncompromising style.} 8.O-O exd5 9.
cxd5 a6 {One of the sharpest variations in modern Chess: White has a 
mobile majority of Pawns in the centre, but Black can generate tactical 
chances both on the Queenside and the Kingside.} 10.a4 Re8 11.Nd2 Nbd7 12.
h3 Rb8 13.Nc4 Ne5 14.Na3 Nh5 15.e4 Rf8 {The Rook returns in order to lend 
more punch to the ..f5 thrust.} 16.Kh2 {Safer was 16. Qe2, discouraging 
...b5.} 16...f5 17.f4 {Not 17. exf5 Bxf5 18. g4? Bxg4! 19. hxg4 Qh4+ 
winning. But now if Black's Knight retreats 18. exf5 really is strong. 
However...} 17...b5 $1 {A magnificient conception, whether or not it is 
completely sound. Black leaves his Knight to its fate for seven moves and 
relies on diversionary tactics.} 18.axb5 axb5 19.Naxb5 {If 19. fxe5 Bxe5! 
threatening both 20... b4 and 20... Nxg3, would be very strong.} 19...fxe4
20.Bxe4 {Now if 20. fxe5 Bxe5 21. Bf4 Nxf4 22. gxf4 Bxf4+ 23. Kh1 Qh4, 
gives Black a murderous attack.} 20...Bd7 21.Qe2 Qb6 22.Na3 Rbe8 {Kasparov
is a Pawn down and when he retreats his attacked Knight on e5, then White 
can play the strong Nc4 and yet, it's Korchnoi move! White has an extra 
piece but some of them are poorly placed, e.g. the a3-Knight, while Black 
has many advantages on the King's wing. In fact, Black has full 
compensation here.} 23.Bd2 $2 Qxb2 24.fxe5 {At last, White accepts the 
bait -- and his position rapidly disintegrates.} 24...Bxe5 25.Nc4 Nxg3 26.
Rxf8+ Rxf8 27.Qe1 {An admission of defeat, but there was no adequate 
alternative.} 27...Nxe4+ 28.Kg2 Qc2 29.Nxe5 {Or 29. Rc1 Qd3 threatening 
30... Qxh3+. Now 29... Nxd2 wins.} 29...Rf2+ {Kasparov: "This spoils the 
game and makes the win uncertain. I had prepared for 30... Kg1 but..."} 
30.Qxf2 $1 Nxf2 {White's Queen sacrifice still keeps him fighting on.} 31.
Ra2 $1 Qf5 $1 32.Nxd7 Nd3 {Kasparov: "After the game I devoted an enormous
amount of time to analysing this position. In severe time-trouble Korchnoi
played poorly..."} 33.Bh6 $2 {White should play 33. Ra8+ Kg7 34. Ra7! -- 
as Korchnoi pointed out immediately after the game. This still ought to 
hold the draw.} 33...Qxd7 34.Ra8+ Kf7 35.Rh8 $2 Kf6 36.Kf3 $2 Qxh3+ {White
lost on time. A magnificent clash; exciting, knife-edge Chess. White's 
33rd move threw away a possible draw but, on the whole, Kasparov fully 
deserved to win! The game was a portent of things to come. In the 
Candidates' semi-final match between Kasparov and Korchnoi, which took 
place the following year in London, Kasparov demolished his older opponent
by four wins to one, with six draws.} 0-1
