Its a simple tactic but im glad i found it with less than a minute on the clock. Black to play and win

A forced mate from one of my games today

I don’t think I’m ever getting any better.

What about it?

You can actually see twice since the beginning of the year when I’ve had major depression, and then later got myself together. Other than that I’ve never actually improved.

my next move is a brilliant, can you figure out what the move is?

What is a move like this called?

What about it?

It's my first time playing a pre-emptive king safety move. Have seen professionals playing them quite often. Wanted to play f4, but it allows Qb6 check. Even if I couldn't see anything too dangerous about it opponent has a dark squared bishop too so it's inevitable that I have to move the king to safety sooner or later. Figured it's better to do it now as there's nothing critical going on than later to face some fork.

Did I play against a cheater? Played someone who managed to get a 92.8 percent accuracy in 800 elo blitz after 25 moves. Link to the game : https://www.chess.com/game/live/85568449149

I went from -12 to this (I'm white) and yes, I won by mate

Was there a better thing here than drawing the game for black?

My first bullet win by checkmate

What about it?

Mostly won on time or got dominated! But got this one in a split second

why would Qf5 be the "best" move here?

Stockfish being weird

What about it?

The trade is exactly what I want instead of greedy Qb5. Two rooks vs one rook endgame sounds great. Marking this as inaccuracy seems wild
