Take more time to look at your opponent's moves.
On move 10, you could have taken the bishop on f5.
Ask yourself what your opponent could do if you made a move you are considering.
On move 19, you played Na4 and black took your knight.
A more difficult one to spot is when you retreated your queen on 31, but still important to see. Black forked your rook and queen with c4.
39. Qxg4+ could have saved you.
I'd really like to improve, but I have no clue what I should learn or practice. I'm also not sure what I'm doing wrong during most of my games either. (I feel like I just have trouble recognizing my mistakes or why they're mistakes)
I'd really appreciate some advice/tips or pointers. ^^
