Bg5 $1 {Attacks a potential blockader and aims to control d8, the  queening square.} d5 $1 {Actively trying to defend against White's idea.} 3.  Bxf6 {Removing the defender of the blockading d-pawn.} exf6 4. e3 Bd6 5. c4  dxc4 $5 {Removing the blockader; but if 5...c6 6 cxd5 cxd5 and Black's d-pawn  is weak.} 6. Bxc4 O-O 7. Nc3 c5 {Threatening to eliminate the d-pawn, but  White easily bypasses this.} 8. d5 {One step closer.} a6 9. a4 Qc7 10. Nf3 Bg4  11. h3 Bf5 12. O-O Nd7 {Black is getting worried so he begins to pile up  blockaders in front of the pawn.} 13. Be2 Rfe8 14. Nd2 $1 {On its way to e4 or  c4 to remove the blockader.} Bg6 15. Nc4 f5 16. f4 Nb6 17. Nxd6 $1 Qxd6 18. a5  Nd7 {Now to make progress White must eliminate his weak a-pawn and also direct  Black's pieces from the d-file. So he pretends to attack on the kingside.} 19.  e4 $1 f6 20. exf5 Bxf5 21. Bd3 Bxd3 22. Qxd3 {Now White stands well. Black has  only one minor piece left to blockade with, has weakened his position slightly  and has little chance of counterplay. Objectively he should now sit tight and  await developments.} b5 $6 23. axb6 Qxb6 24. Kh1 Qxb2 $2 {This is a waste of  time, taking the queen away from the danger zone d6-d8 and allowing White to  get a rook into play to assist the advance of the d-pawn.} 25. Rab1 Qa3 26. Rb7  c4 {Black must get his queen back.} 27. Qxc4 Rac8 28. Rc7 Nb6 29. Qc6 Rxc7 {30  Qxe8+ also wins.} 30. Qxc7 Rc8 31. Qxb6 Qxc3 32. Qe6+ Kf8 33. Re1 Qc7 {Now  Black is powerless against the advance of the d-pawn. The mating threats are  purely diversionary.} 34. d6 $1 Qd8 35. d7 $1 {A fitting conclusion would have  been 35...Rb8 36 Qc6 Kf7 37 Re8+ when White completes the plan begun with 1 d4.}  1-0
