I don't have an answer, but I'd like to second the motion, and perhaps clarify it a bit.
I would like an option on chess.com to go to Play (the computer), and choose something like "I want to play White against the Petrov", or I want to play Black in the Advance French. Whatever. In other words, I just want to be able to control the computer's first few moves.
Hi forum!
I would like to practice my opening repertoire against a computer that varies its book moves. Basically so that I can choose an opening to practice (let's say the Slav Defence) and then have the computer play various lines against me.
Does anyone know of a computer that can do this?
All the best
