My thoughts on four stages of a tough game

I've just recently started playing more correspondence chess rather than blitz, trying to really improve my game by thinking more deeply, and getting to know different openings. This was a tough game, and I lost in the end, partly because I made a terrible mistake mid-way through from which I never recovered, but I am quite proud of the way I did not crumble. I fell to a two pawn deficit because of my mistake, and the deficit was two pawns when I eventually resigned.
