Obviously move 5 is a ridiculous error for black, he can block with bishop knight or pawn.
Move 8 isn't good either for black, Ke8 or Rf8 block your knight taking on f7.
10. Did you just miss his bishop?
You should still be easily winning though.
Honestly it doesn't really need analysis, you know you shouldn't take there with your queen.
Hello. I started learning chess just a few months ago, but I've got really interested in developing my play style. At the moment, my Elo is somewhere between 600 and 700. This is a game I played today against the computer (easy, 800), where I had a big early game advantage but I messed up in midgame. Although I ended up winning, I wasn't happy about how I did it. Maybe someone could take a look at the game and give me some advice about how to improve my mid and endgame strategy. Thank you! :)
