My first brilliant move. (Actually 2nd but the last time I didn’t have any more free analysis left so I couldn’t go through the game move-by-move)

please help

Am I wrong to decline a draw here? I started playing recently

Why is this not a blunder (took bishop leaving queen hanging), once trades are done can’t white just move queen to avoid fork?

I sacked four pieces to force a mate towards this position, I'm white btw

How this not a brilliant move?

What about it?

I won the game after he captured the bishop.

Why don’t we move up P-h6

What about it?

Why don’t we do that to threaten Bishop? I heard it could be a blunder but why?

So this happened after I told the opponent to try King + queen mate

Is this worth being pleased about or is it easily achievable? My Rapid ELO is ~1000.

Spotting Pins

What about it?

Haven’t really played chess in 20 years. From here I took e5, white Re1 pinning my Queen to the king with no escape. How do you all recommend spotting something like that defensively?
