A Game of Mistakes

Both sides made mistakes and missed opportunities in this game.  It was a good game, but not one I'm going to hang on the fridge!

EDIT: My notes for move 40. c5+! didn't save, and I wanted to explain that move.  That exclam is Fritz's, not mine.  Black was putting a lot of pressure on me with his connected pawns, which were getting close to queening.  Black's DSB was central to their success, and I opted I to kill it.  I wasn't sure during the game whether giving up the exchange was a good or bad move.  Fritz loved it, apparently.
