Well, I think one of the moves that was key to my downfall was when I moved my Gold General to 5b (turn 24) because that allowed you to go straight to the end of the board.
I also made a mistake when I belatedly began moving my King towards the corner and made room for him to go through beginning on turn 26 (I had only just found out about that strategy and probably would have made different moves in the early game had I been aware of what you were trying to do). While I was doing this I largely ignored your Silver General coming up towards me, so I was ill prepared when you got there.
Then of course I stupidly moved my Bishop to kill the promoted SG (I think that was my best option at the time, so it was really a series of stupid movies that culminated in the taking of my Bishop). I think that was a pivotal point of the game, as it gave you the upper hand for almost the rest of the game.
I then made a distraction with my pawn, which bought me some time, and I think that was a smart move, but you countered it well enough that it did very little to help me in the end.
Then I made a series of fairly good moves, but you paratrooped in your Bishop on turn 51 which gave you a huge advantage later and forced me to become defensive for the rest of the game.
On turn 55 when you moved your promoted Bishop to a square adjacent to both my Rook and your promoted Rook, you gained a further advantage since you had another valuable piece to drop behind my ranks.
From there it went downhill and I had very little in terms of strategy, as I was just fighting for my life at that point. I knew it was over as soon as you had two promoted rooks at the end of the board and it didn't last long after that of course.
Any thoughts on how I could have turned the game in my favour at one of these points in the game?
EDIT: I suppose that was more a description of the game than an analysis...
