If you get two yesses, then the only no is certainly the truthful guard. Because he will ALWAYS answer no to "will you stab me if I ask a tricky question?".

And to simplify that question, hmm.... Yeah, you could just say "What is one of the doors that doesn't lead out?". Silly me.

A question is either obviously tricky or not obviously tricky.

If it's obviously tricky then it's tricky.

If it isn't obviously tricky then the questioner must be asking it to try and gain some information by asking a non-tricky question.

Thats pretty tricky.

Well, again, if that's the case, then there's no point trying to logic our way out of it. Might as well go down fighting!
