I am inconsistent in chess! I saw this one opportunity this once and took it! I usually lose many good plays for not paying attention!

My elo ranges from 300 to 400 because I am inconsistent, but I will try to get better, this one game got me excited, I felt very good when I saw this one opportunity for a beautiful checkmate in only 3 moves.

It was accidental, I didn't plan 3 moves ahead, I am not that good, it just so happened that my opponent and I did the right moves at the right time and I saw this opportunity at the last moment!

My opponent has a rating of 383 and I had a rating of 363 at the time of this match
