The opening was good for me. Inaccurate play in the middle game cost me a pawn, but I was sure that I could hold the resulting Bishop endgame. My opponent then sacrificed a pawn, so the material was equal.
We reached the following position. My last move was Kd5-d6. This move is a blunder because it allows White to play Bf6! It is interesting to note that Bf6 only draws if I had played Kd5-c6!
I lost this game because I failed to look at winning plans for White, was too confident of my drawing chances in my opponents time trouble.
I have seen Bishop endings where the theme was to sacrifice a bishop to queen a pawn, but in this game I forgot all about it. There is so much to remember!
I spent a lot of time going over this game and learnt a lot about Bishops of same color endings.
