I'm looking for an old comic with Scrooge McDuck I think, or maybe Donald Duck. I read it in French was I was young (late 80s or beginning of the 90s).
He is facing a chess player, some kind of gigantic mountain man, with a big beard. This man always wins
because he is so scary and intimidating, with his big scary look, that the player in front of him loses all his confidence and kind of forfeit.
