If I were black this this is how I would try and attack. Try and get the king to penetrate along the route d4-e3-f2-e1. Only the white kind can prevent that maneuver. Secondly, attack with the queenside pawns by b5-a5-a4-a3-a2-a1. The white bishop has to stay on a diagonal protecting d1 to prevent the d-pawn from queening and the white king is tied up preventing the black king from invading. I don't see a way to prevent this double treat. You might think of attacking with white's kingside pawn but just as soon as you move the g3 pawn you give the black king a new invasion route f4-e3-f2-d1. My move in 48. ... Bb2 Chris
