Game analysis forum

I thought it would be good to post games for feedback.

Here is a game from our first match. My first game was terrible and not worth posting.  From the second game  I am interested in thoughts on moves 13, 31, and 45 in particular. 

I do not know digital, maybe at 13 I would move Kh8, because if I were white, after g6, I would play Bh6 anyway.

nice finish, sometimes the chess.com analysis seems strange to me too.
