You know of 33 points and you know of an 8-card fit. The math tells you that 6 should be a good slam but you might as well check Key-Cards, that's why the convention was invented.
So you bid 4NT and partner answers 5. What do you say?

You say "Darn!" You are missing just one Key-Card, but you are also missing the trump Queen. And with partner holding only a 4-card suit that Queen might well win a trick. Knowing that at best the slam will depend on a trump finesse you pass 5.
