Your judgement, please

6/27/2009 – Opposite-coloured bishops tend to favour the attacker in middlegame positions, yet in endgames they can sometimes save the weaker side despite being one or even several pawns down. What do you think about the position after 66...Ke6? A) White has nothing better than to go for the trade b7 against e4, when despite two plus pawns his victory is written in the stars. B) There is a clever way to keep the pawn on e4, increasing his winning chances considerably. C) The first player can win by force. The solution is here, but first ponder over it with a larger version of the diagram.
