Too close for comfort

I am at around 550 elo. And I win most of the matches by resignation. It feels bad not doing a mate. Why does everyone keep resigning? (it's after taking their queen most if the times)

Why does chess.com consider this a mistake and not a blunder? (I played h5 there and won)

We've all been there. But castling because you can't think of another move is not necessarily the best way forwards.

Help whats the best move

Nothing like watching your opponent snatch defeat from the jaws of victory.

What about it?

At one point he had my rooks forked with a pawn and got cute and tried to work around losing the pawn, instead of just taking a rook.

I guess you could say things are getting pretty serious

Understanding position and piece activity

What about it?

What should white do here?

What pawn is lost

What about it?

Computer says it's a miss bc I lose a pawn. Which pawn ?

first time winning against emir! (around 500 elo against humans)

Isn’t this checkmate?

What about it?

The puzzle today, I thought would end with this move.
