My first rook sac

My opponent was winning and then i did this Can you guess what happened next ? I guess as a 900 this was preety good to find 🙃

I... I don't even know how I managed to turn it around

I'm hardstuck 1200 points, any tips on what i should be improving? i play the caro kann and the italian game (giuoco piano game: main line, giuoco pianissimo game/knight attack). when i can't play the caro i improvise and transform the game into a caro which works fine but i dunno, any tips please??

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
