I Fell For a Beginner Checkmate in OTB Classical!

Well, this is embarrassing. I hope this game teaches you that anything can happen. You can beat experts, masters, etc. They all make blunders, even beginner ones sometimes.

It can also teach you not to let your guard down! Sometimes we lose sight of the beginner tactics if we don't continue to practice them. Keep doing Puzzle Rush and regular puzzles to stay sharp! This was a 60+30 game, and I still had 10 minutes on the clock (no time management excuses). 

I'll post the video review and PGN files below. Please be nice in the comments
