Be2 dxc4 7. Bxc4 c5 8. d5 e6 9. dxe6 Qxd1+ 10. Kxd1 Bxe6 11. Bxe6 fxe6 12. Ke2 {A dynamic position has arisen. True Black has an isolated e-pawn. However, this is compensated for by his queenside pawn majority and slightly more active pieces.} 12... Nc6 13. Rd1 Rad8 {13...Kf7 Giving the e-pawn protection is preferable.} 14. Rxd8 Rxd8 15. Ng5 {A well disguised idea. The knight is actually heading to e4 but is currently attacking the e-pawn.} 15... Re8 16. Nge4 Nxe4 17. Nxe4 b6 18. Rb1 { Freeing the bishop from the defense of the b-pawn.} 18... Nb4 19. Bd2 { The a-pawn is poisoned.} 19... Nd5 {19...Nxa2 20.Ra1 Nb4 21.Bxb4 cxb4 22.Rxa7 Bxb2 23.Rb7 Regains the pawn while leaving Black with all the weaknesses.} 20. a4 {White restrains the enemy pawn majority.} 20... Rc8 21. b3 Bf8 { The Black bishop heads to e7 to keep the reins on the White knight.} 22. Rc1 Be7 {22...Rc7 would have protected the Black rook and thus of broken the pin.} 23. b4 c4 {23...Kf7 24.bxc5 bxc5 would leave Black with an isolated pawn at c5. } 24. b5 Kf7 25. Bc3 {Remember these three steps to winning an isolated pawn, blockade, attack, destroy.} 25... Ba3 26. Rc2 Nxc3+ 27. Rxc3 Bb4 28. Rc2 Ke7 29. Nd2 c3 30. Ne4 Ba5 31. Kd3 Rd8+ 32. Kc4 Rd1 33. Nxc3 { White has followed through on his plan, blockade, attack, destroy.} 33... Rh1 34. Ne4 {A deep move to understand with variations. The idea is that the h2 pawn is insignificant compared with the dominant posts White gains for his pieces.} 34... Rxh2 35. Kd4 Kd7 {Played to stop the White rook from penetrating to the 7th. 35...Rxg2 36.Rc7+ Ke8 37.Ke5 leaves the Black king in a mating net.} 36. g3 Bb4 37. Ke5 Rh5+ 38. Kf6 Be7+ 39. Kg7 e5 40. Rc6 Rh1 { White has an overwhelming advantage because of his swarming pieces.} 41. Kf7 Ra1 42. Re6 Bd8 43. Rd6+ Kc8 44. Ke8 Bc7 45. Rc6 Rd1 46. Ng5 Rd8+ 47. Kf7 Rd7+ 48. Kg8 {Black resigned because he will be unable to save his kingside pawns.} 1-0
