Black should have avoided creating a "second weakness" that helps White convert his advantage. 27.exf6 gxf6 28.f5! exf5 29.Rxf6+/- h4 30.gxh4 Rh8 31.Rxa6 Rxh4 32.Kxb5 Rxh2 33.b4 f4 34.Rf6 Rxa2 35.Rxf4 A very tough R+P ending has arisen. White&aposs great king position and connected pawns give him winning chances. 35...Rh2 36.Rf7 Rh5+ 37.Ka6 Rh6+ 38.Ka5 Rh3 39.c4 Kc6 40.Rf6+ Kc7 41.c5 Ra3+ 42.Kb5 Ra1 43.Ra6 Rh1 44.Ra7+ Kc8 White struggles to find the optimal placement of this pieces. 45.Ka5 Rh5 46.Kb5 Rg5 47.Ra2 Kc7 48.Rd2 Rg1 49.Kc4 Rc1+ 50.Kd5 Now the b-pawn is free to advance. 50...Rb1 51.Rd4 Rb2 52.Kc4 Rb1 53.b5 Rc1+ 54.Kd5 Rh1 55.b6+ Kc8 56.Ra4 Rh5+ 57.Kc4 Rg5 58.Ra8+ Kb7 59.Rd8 Rg7 60.Kb5+- If 60...Rh7 61.Rxd7+!
