Poison Pawn Tactic that Won the game, happy hunting.

Shouldn't this be a blunder?

Got him

Is This Position Winable? White To Move.

Could my opponent have castles in this position? (I moved knight from g5)

It’s not mate, but it wins.

Do you see why this move is terrible?

Ok, can anyone explain this one?

Is this any good?

this was my latest win how does it look?

Can anyone explain why this is brilliant/a winning move?

I knew this was the right move in the moment, but when I look at what the next moves should look like, it’s just exd4 which is what black plays. I ended up winning this game but I feel like there’s an easy checkmate early on here. Could anyone shed some light on this for me?

Brilliant Move?

Why was this love from my opponent considered brilliant? He blunders his Queen.
