1.d4 Nf6 2.c4 c5 3.Nf3 cxd4 4.Nxd4 e5 5.Nb5 d5 6.cxd5 Bb4+
Kasparov himself has played Bc5 in this position.

[An alternative considered by Kasaprov was 24.f6 gxf6 25.gxf6 Re1+ 26.Kf2 Rh1 27.Kxf3 Rf1+ 28.Kg3 Rxf6 29.Bf4+- ]

24...Bxf5 25.Kf2 b5 26.Be5?
A self-critical Kasparov gave this move a question mark. [26.b4 "Cutting off the knight!" (Kasparov); 26.Nxb5 Re2+ 27.Kxf3 Bg4+ 28.Kg3 Rxb2 29.Nxa7 Rb3+ 30.Kg2 Bf3+ 31.Kg1 Bxd5 32.Nc8 In this variation Black would still have some play.]

[26...Bg4 27.Kg3 f6 28.gxf6 gxf6 29.Bxf6 Rf8 30.Be7 Rf7 31.Bc5+- ]

Not the best continuation. [What is wrong about simply taking the pawn on b4? 27.axb4 Nxb4 28.Kxf3 a6 29.Ra4 Nd3 30.Rxa6 Nxb2 31.Ne4 Bg6 32.d6 ]

[27...Bg4! 28.Nd6 Rb8 29.axb4 Rxb4 30.Ra2 (30.Rxa6? Rxb2+ 31.Kg3 Rg2+ 32.Kf4 f2-+ ) 30...Nb8 31.h3 Bxh3 32.Rxa7 Rxb2+ 33.Kxf3 Bg2+ 34.Ke3 Bxd5 35.g6 Rb3+ 36.Kd2 fxg6 37.Rxg7+ Kf8= ]

Very elegant and study-like! For a game in a simultaneous exhibition this is quite sensational (Deutschmann). It is interesting to see how long the best chess engines in the world take to find this line.
