On second thoughts, "f1 takes ..." seems more likely, where "..." is an algebraic square which could mean something like "it up the bum".
On third thoughts, how about "f1=Q+"?

I would never have got that. I've played chess for far too long to read "exf1" as anything other than "e takes f1".

Yes, the point being that it is impossible to achieve in a legal game so players with lots of experience of normal chess won't be inclined to put the king in check by both rooks at the same time!
