Kasparov is a formidable opponent. Black judges his position safe and embarks upon a slow reorganization with c7-c6 and Nf8-b6 or Nf8-e7. Kasparov is quick to react.

13.h4
Threatening to trap the Bg6

13...h6
making luft on h7

14.d5
A pawn sacrifice to open lines for the Qd1 and the Bb2

14...exd5 15.Bg2 c6
Black's up a pawn, but check out the Na7 and Ra8. Even the Bf8 cannot move with consequences for the Rh8. It's chess magic.

16.0-0 f6
To try to activate the kingside by blocking the long diagonal, but every pawn move creates a weakness, here on e6 and especially g6.

17.Re1
To support e3-e4.

17...Be7 18.Qg4
Taking aim on the new kingside weaknesses. If the Bg6 moves, white will play Qxg7

18...Kf7 19.h5
Forcing the Bg6 back to its newly created sanctuary on h7, but the black king is horribly exposed.

19...Bh7 20.e4
Opening lines for the attack. White will have five pieces moving in for the kill. Black can only defend with four

20...dxe4 21.Bxe4
The exchange of the light-squared bishops will permit the white queen to take the g6-entry square.

21...Bxe4 22.Nxe4 Nc8
Trying to rush in another defender.

23.Rad1
Two attacks upon the backward d-pawn.

23...Ra7
Diagram

24.Nxf6!
Crushing!

24...gxf6
[24...Bxf6 25.Qg6+ Kf8 26.Bxf6 gxf6 (26...Qxf6 27.Re8# ) 27.Re6+- ]

25.Qg6+ Kf8
First law in operation. The king can't move. All we need is check.

26.Bc1
Of course with the idea of Bh6

26...d5 27.Rd4
Reinforcements... Rg4 is coming

27...Nd6 28.Rg4
threat=Qg7+ and Qxh8 [28.Bxh6+ Rxh6 29.Qxh6+ Ke8 30.Qxf6 ]

28...Nf7
Defending Rh8 and the h6-pawn.

29.Bxh6+!
But the Nf6 is overloaded.

29...Ke8
[29...Nxh6 30.Qg7+ Ke8 31.Qxh8+ Kd7 32.Qxh6+- ; 29...Rxh6 30.Qg8# ]

30.Bg7
[30.Bg7 Rg8 31.h6+- ] 1-0
