Rae3 Nf6 {This was not known to the chessplaying public at the time but I was prepared for it. 18...f4 19.R3e2 Qf6 20.e5 18...Nb6} 19. Nh2 {I made this move almost instantly, demonstrating to Karpov that I was the one who had the opening under control. At this point White, speaking objectively, has a clear advantage, with more active pieces.} 19... Kh8 {19...fxe4 20.Nxe4 Nbxd5 21.Nxf6+ Nxf6 22.Rxe8 Nxe8 23.Qd3} 20. b3 bxa4 {20...c4 21.bxc4 bxc4 22.Nxc4 fxe4} 21. bxa4 c4 { This takes control of the d3-square.} 22. Bb2 {My plan is simple. I want to attack, attack, attack! Karpov should have completed his development now with 22...Rc8, but instead he panics and releases the tension in the center.} 22... fxe4 { 22...Rc8 23.Rf3 fxe4 24.Nxe4 A very messy position with unclear complications.} 23.

Re6 { 24...Nd3 25.Bxd3 cxd3 26.Qh5} 25. Ng4 {25.Nf3 Qe8} 25... Qe8 {But here Karpov goes astray. Still, it is hard to find a good defense. 25...Nd3 26.Bxd3 cxd3 27.Nxh6 Rxh6 28.Ng5 Qd7 29.Re6} 26. Nxh6 c3 { 26...Rxh6 27.Ng5 Qh5 28.Kh2 There is no defense for Black.} 27. Nf5 cxb2 28. Qg4 Bc8 {Black has an extra piece and an advanced passed pawn, but his king is still in serious danger. In fact, there is no defense.} 29. Qh4+ {29.Nxg7 Rxe4} 29... Rh6 { 29...Kg8 30.Ng5 Rxe1+ 31.Kh2 Bxf5 32.Bxf5 Rh1+ 33.Kxh1 b1Q+ 34.Bxb1 Qe1+} 30. Nxh6 gxh6 31.
