Anyone else's rating chart look like this?

My ELO was super high right away (the plateau is when I stopped playing)

Got my first brilliant move apparently. Mate in 3, black to play

Is this an opening?

Mate in 3. White to win!

Got drunk last night and started playing chess at 94.3 accuracy.(my rating is 745)

After the knight takes the black queen, can you find the M6 for white?

What is this Mate Called?

An absolutely savage puzzle from my game against the PEKKA bot. White to play and win

Why is this brilliant?

BRO HE SLIPPED AND I GOT SO LUCKY 😭😭😭 I FEEL SO BAD

he resigned the game.

What am I missing? My plan was to move queen to b1, protecting the rook and capturing the knight with the rook. Why does the engine says I could capture the knight right away with the unprotected rook?
