See the diagram for some analysis.
All in all, at your level you play quite well. You develop very naturally and realise the material advantage confidently. You don't do many simple tactical mistakes in this game although practicing tactics is almost certainly one of the fastest ways for you to improve. Few notable moments are around move 9 when you seem to be unnecessarily worried about the b-pawn - black will fall too much behind in development if he takes it - and at move 11 where the queen exchange is a bad positional mistake. After the exchange black is probably better whereas with queens on board you have changes to get an advantage with an attack.
Hello, I am new to chess.com and "serious" chess. By that, I mean that I've only recently started studying openings, endgames etc, although I've known basic opening principles and tactics for quite a long time. I would dare to say that my rating here is quite inflated, seeing as I've only played three games. It is probably closer to 1400. I have annotated my most recent game below, and I'd like some comments on my general play and my thought process. Thanks.
