Is is possible to give a weaker player a handicap, such as removing a piece?
i do not think that is possible

You could achieve it by giving takebacks (in an unrated takeback game).

I found a way to create a handicap. We start the game with him moving e4 and I move h5. Then he moves anything that doesn't block the bishop's diagonal and I move Rh4. He moves bxh4, and I let his bishop return safely. It works well for us and we have a great time playing chess.

I've been Warned (by Staff) when I'd inquired by support ticket, that even for unrated games 'dropping' material for any purpose including handicapping is 'high risk' (I took that to mean, being shutdown as a 'cheater' if that activity were noticed).

ps. Yes, I'd certainly like to be able to play 'handicap' games on this site, especially in the Live Chess area.
