what do you think of (an optional) feature to hide opponents ratings until you have finished the game. the idea is that you do not 'appraise' your opponent and play your natural and best game. 

to do this properly the challenge should be open and chess.com should not match for the closest ratings in this mode.

(this is certainly different to playing non-rated game, something which i lack the motivation for.)

This is an interesting idea which has been suggested before. Personally, I think it is necessary to train yourself to not focus on the opponent's rating even when it is right there in front of you.

Yeah, I agree
