Why did my opponent resign?

Why not king e8 to avoid fork?
I would guess they didn't want to play uncastled and a pawn down.

Maybe the queue at the post office cleared up soon and it was his turn.
Maybe his boss came into the office.
Maybe he was in the car waiting for his girlfriend and she finally got out.
Maybe his wife told him to stop playing chess and pick up the baby at the swimming pool.
Maybe his father told him to stop playing chess and do his homework.
Maybe his sister told him to stop playing chess because his father and mother are very upset because he doesn't do his homework and they're on their way.
Maybe he just got bored of playing.
Who knows ?

I don't understand
It was more bad for me - can I promote one of my pawns despite his rook or not

In the final position it's white to move. White wins with Rg6. You were lucky the guy disconnected.

Their mothers probably called them and they wouldn't listen when you say that you can't pause the game

mine says i had a advantage but i dont see why
