I started playing correspondence on chess.com purely for the fun of it and to gain some deep learning (i.e. there's no prize involved).
We are about 10 moves in and coming close to me being out of book. To help my learning, I'd like to set the position up against a computer and spar against that. I am not interested in the computer's evaluation, recommended moves for me etc. I'm really just interested in practicing from a specific position.
My question is, is it ethical to spar against a computer between moves in a correspondence game?
