At d4 it may be exchanged, in which case Black dissolves his doubled pawns by the recapture; or if it is driven back by c3 the White d-pawn is left weakened} 13. Rfd1 Nc6 14. c3 Qe8 15. Rac1 Rd8 16. Nf1 {White could have advanced his backward d-pawn, but this advance of course, has the drawbakc of allowing Black to get rid of his doubled c-pawns. Also the position would be opened up for the two Bishops} (16. d4 cxd4 17. cxd4 exd4 18. Nxd4 Nxd4 19. Bxd4 Qh5 $1 20. Rxc7 Bd6 { So, one way or another it seems best for White to continue maneuvering}) 16... Rf7 17. Ng3 Bf8 18. Rd2 {White gives up his last good chance to play d4} 18... Rfd7 19. Rcd1 a5 $1 {Now that the d-pawn has been definitely relegated to the status of backward pawn it is a weakness. Black therefore loses no time in seeking to create a second weakness in White's position} 20. Ne2 (20. d4 cxd4 21. cxd4 exd4 22. Nxd4 Bc5) 20... a4 21. bxa4 (21. c4) 21... Ra8 $1 22.

Rc2 Rd6 {Now the game acquires a new aspect and Black begins to maneuver in earnest against the enemy weak points} 28. Nd2 Rb6 29. Ndb3 Ra3 30. Kh2 c5 31. g3 { In order to play Pf4 later, but he is never able to get it in} 31... Qc8 32. Qf1 Bh6 33. Qg2 Bd7 34. Re2 Qc7 35. Rde1 {White indirectly prevents ... Pf5 but putting indirect pressure against Black's e-pawn} 35... Re6 36. Qf3 { Again restraining ... Pf5} 36... Kg7 37. Rc2 Ba4 38. Rb2 Rb6 39. Ree2 $2 Rb4 ( 39... Bxc1 40. Nxc1 Bd1 $19 {both players overlook the win of the exchange}) 40. Qg2 {Up until now White's defensive lines have held under heavy pressure. All the same he has had to concede terrain, and his pieces have been forced back all along the line. In the closing phase of the game Black decides to give up the two Bishops, as in this way he is able to facilitate the attack on the d-pawn} 40... b5 $1 41. cxb5 Bxc1 42. Nxc1 Rc3 43. Qf1 Bxb5 44.
