FB keeps showing me Chessnut


Hmm. I assume FB means Facebook. You are somehow playing Chess.com opponents on Facebook. Is that right? Why not play directly on Chess.com?
You want to play with real pieces. I assume you have one of those electronic boards that can be integrated with Chess.com.
There are instructions on how to use those devices.
