Whites plan is to immobilize the black majority and to activate his own majority.} 27. a4 {One holds two} Rd8 {Black cannot let white dominate the d-file.} 28. Rxd8+ {Hence the rooks are exchanged, as usual.} Qxd8 29. Ne5 {The white knight is underway to c4} Qd5 30. Nc4 {Now blacks pawn majority is securely immobilized. Moreover, the base b6 is under attack, forcing black to defend it. Thus immobilizing a defender.} Nd7 31. b3 f5 {Trying to immobilze whites pawn majority} 32. Kf1 Kf7 33. f3 Ke7 {Bringing the black King closer to the center, where he can chose between freeing his knight from the duty to defend b6 or help to immobilize whites pawn majority} 34. Ke2 Qe6 {Defending both f5 and b6} 35. Qc3 Nf6 {The knight protects g7} 36. Kf2 Kd7 37. g4 {If black takes, the white passer will be a fact} Kc6 38. Qe5 Qxe5 39. Nxe5+ Kd5 40. Nc4 fxg4 41. Nxb6+ Kc6 42. Nc4 {All of a sudden, black is going to lose a pawn. Giving white two passers.} gxf3 {With the vague hope to convert the g-h pawnduo into a black passer} 43. Kxf3 Kd5 44. Nxa5 {White won a good pawn and the rest was not that difficult (when you are Karpov). Knight endings are similar to pawn endings, so the extra material is much more important than in other endings!} g5 45. Nc4 h5 46. Nd2 Ke5 47. e4 Ne8 48. Ke3 Nc7 49. Nc4+ Kf6 50. Kf2 Na6 51.
