When you go to someone's profile you can see lifetime score against you (wins, losses, draws)... I believe you may have to go to your archive, choose fog of war and their username, and count it all up. Chess.com only does the lifetime score for you.
@ninjaswat Going to someone's profile doesn't work because chess variants are not covered there. Archive's search bar is simply busted, so doing it from there also doesn't work.
I would like to see what my overall score is against some players. Is this possible?
