Guess my ELO

Bit short but my highest accuracy game (95%).

Smooth mate in 4 I missed (Black to play)

Should we call the ambulance for black king? Or is there something else we can do? Black to play

I decided to troll move and it somehow came out as brilliant.

What about it?

In this position my opponent blunders his queen. I decided to troll him by making a completely unnecessary in-between move before taking his queen. Either way, I would have lost the knight in return for his queen. My opponent resigned after this move. (maybe the move upset him too much). Analysing both scenarios shows the games continuing as normal. My only guess is that Bxf4 is somehow is positionally better for black than Kxd3 which again makes 0 sense since it makes the king more exposed? Can someone try to explain?

Why is this move inaccurate and why is bc4 better? Don't I just win a queen here?

A brilliant according to stockfish

I'm gonna get you get you get you, One way or Another

My best move ever, sacking the queen and rook

Wild final position, with a hanging bishop as my only protection. I don’t even know

Find the best move for both players

What about it?

Friendly match me and my friends had at school , no draws were allowed including threefold so we were puzzled on what would be the best move for both players here. can you find it?
