Duo?

Play a language opening and see if you can beat him. That is when it gets really difficilt (no flagging)

"language opening"?

An opening related to a language like the polish, the french, the italian etc. We have a discussion in the chess.com club
I dont know why, but duo is not as strong as engine
If you review a game against duo, its rating will show as one.
Also, I beat him

Do you guys have any idea how strong it is though???
