Trying to annotate a game for the first time.
Good job.
I don't think many people post analysis these days that hasn't been checked by an engine.
What you said made pretty good sense to me but I think you were too hard on Bd3.
Yeah, probably I'm too hard on Bd3. It probably shouldn't make the summary.
I think my own summary is that white blundered a pawn on move 12 and maybe should have played Be3, not only to defend the D pawn but because this is a development move. Black soon made some mistakes too and finally white put the rook on the 7th, which probably made for a very advantageous position for white. Basically white won because black's bad moves came later than white's.
I think if I annotate my own game again in the next couple of week I'll try to play a 15|10 rapid instead of blitz.
