Qe2 (26. h4! $15 { was probably the lesser evil. However, Black's position is definitely preferable, as the inclusion of the moves a2-a4 and ... a7-a5 has made it very difficult for White to carry out her main plan of b2-b4. }) 26... h4 27. b4 { White feels obliged to begin play on the queenside, but it does not fully work. } 27... axb4 28. a5 (28.

One point is } 33. Rb1 Nd7! { , and the b7-pawn is immune to capture. }) 33. Rxc5 Qxc5 34. Rxb7 Qd6 { Black has won a pawn, but there is a lot of work to be done. } 35. Qb6 Ng4! { White begins to feel the weaknesses created as a result of the ... h5-h4 advance. } 36. Qc7 Qf6 37. Qf4 Qxf4 38. gxf4 { White is probably holding this endgame, but it's not elementary. } 38... Ra8 39. Bf3 Ra1+ 40. Kg2 Nf6 41. Rb6 { The wrong track. The rook is best placed behind the pawn. } (41. Rc7! Rc1 42. Rc8+! (42. Kg3?! Kf8! { and White will not be able to maintain the position of her rook after the impending ... Nf-e8. }) 42... Kg7 43. Kg3 { White will wait until Black's pawn advances to the c4-square and then play Rc8-c5. It is hard to see how Black can make progress. Critically, she is not able to activate her king, since ... Kg7-h6 is always met by Rh1-h8+. }) 41... Rc1 42. Kg3 Kg7 43. Kh4?! (43. Rb8! { was not too late. }) 43... Rc2 44. Kg3 Kf8 45. Rb1? { Voluntary passivity. After this White's position is probably lost. } (45. Rb7 Ne8 46. Rd7 Ng7 47. Bg4 { was the best defensive construction. }) 45... Ke7! { Now the king is free. } 46. Rb7+ Ke6 47. Bg2 Nh5+ 48.
