Checkmated Martin without moving my back rank

My First Brilliant Move!

Is this a mate in 3? Black to move

What about it?

I’d say I’m an advanced beginner. Not very good with notation. The Mate in 2 or 3 or 4 thing has always confused me. Is it Mate in 3 regardless of what black does? Anyway, Black to move, they played Bd4, then Mate in 3 for White. Am I doing this right?

Find the mate in 3. Includes a brilliant!

I made my first brilliant move!

Why can’t I see my puzzles for two days in a row now?

well this definitely was one of the games of all time.

Missed this mate in one

White to move. Idk what to do next, keep losing my train of thought

just did this crazy game to get to 700 on blitz!

Getting close to my goal of being an ultimate 777
