Not "queening"; no real chess player calls it that. A pawn doesn't automatically promote to a queen, though there is almost never a reason to promote to anything else. (Sometimes promoting to a knight is the best move, for its ability to deliver check over defending pieces)
You must accept other type-ins for orthogonally. That is just ridiculous. I'm sure everyone who took this quiz knew how a rook moves but couldn't think of the specific fancy word you wanted
Good point. We should accept orthogonalement (French), orthogonal (German), ortogonalment (Catalan), ortogonalmente (Italian), ortogonalno (Serbian), ortogoniškai (Lithuanian), orthogonaliter (Latin), and ορθογώνια (Greek). Because clearly, no speakers of those languages will have any idea of how to say that in English.
And variant is misspelled.
