I will not comment the match as I don't consider my self in the position to do so. But from my point of view, the match wasn't bad. Then obviously I'm not an expert.
Anyway, the computer doesn't necessarily make perfect judgement sometime. I analyzed some of Kasparov and other well known GM games (such as Fischer) through various engine, and although the matches were quite perfect for a human, some of the moves were marked as "errors" by the computer. That's simply because the computer rating is +3000, which no human reached so far. If I were you I would never let my king move because that makes it weaker. If white could take advantage of your uncastled and unprotected king here, you'd probably be done easily there. Anyway, my only suggestion is to:
- Develop your pawns to the center, knights, bishop AND castle;
- Don't let the opponent make your king move (QueenxQueen example)
I am a total noob player and was very surprised with the analysis of this game. Mobile 1 minute analysis shows I played 23 excellent, 2 good and 3 inaccuracies. 0 mistakes or blunders.
I thought during the game I played way too many pawn moves. Also, my king was harassed mid-game and I moved it keeping me from being able to castle. Certainly that should count as a mistake or blunder no?
Anyways, I was super surprised at this game analysis and how well the computer told me I played.
