Opposite Coloured Bishops – part 11

I am continuing the series of annotated games with endgames with bishops of opposite colours. More examples are here. This example illustrates that weak pawns are vulnerable in this type of endgame just like in any other. A rook is particularly good at picking up weak pawns, while the bishop can help to protect your own pawns.

31.Kg2 White has an advantage, as the Black bishop is in a cage of white and black pawns. As Black tries to free up the bishop with 'g6-g5', his pawns are going to become weak. [31.Kf1 !? planning Kf1-e2-d3, then if 31...Bf6 32.Ke2 Bh4] 31...Bf6 32.Kg3 h6 ? ! [32...a4 !? A much better way to activate the bishop was: 33.Rc2 ! ? (33.a3 ? 33...c2 -0.48) 33...a3 34.Kf3 Kd7 35.Ke2 Bd8 36.Kd3 Ba5 37.f3 Rb8 38.Bb3 0.00] 33.Bb3 g5 34.Bc2 Ke6 35.Rb1 Diagram


35...gxf4+ ? [35...Bd8 36.Rb7 Bc7 +0.48] 36.Kxf4 Notice how many 'pawn islands' Black has. 36...Bg5+ 37.Kf3 Bd8 38.Rb5 d5 39.Ke2 Rc4 40.Kd3 a4 41.Rb8 Be7 42.Rh8 Diagram


All 5 Black's weak pawns start to fall down like leaves from a tree in fall. 42...f4 43.Rxh6+ Bf6 44.Rh7 a3 45.Bb3 c2 46.Bxc2 Rb4 47.Bb3 f3 48.Ra7 Diagram
