Relevant xkcd:
The classic riddle has the caveat that you are only allowed to ask one question so how is asking “what’s 2+2?” going to let you know which door to take?
The solution being, for the singular person on Earth who hasn’t heard already, “If you were the other guard, which door would you say is the safe one?”
Alternatively, the barbarian in the party just splatters one of the guards in one hit and asks the remaining one, “Which door? You’ll go through it first.”
Doors tend to be weak to slashing or bludgeon so i keep an axe and hammer in my bag for just such a purpose.
Signed, your local barbarian
Alternatively: the one that explained the riddle is a liar, and they both lie.
Thanks! I was suddenly ashamed that I’d never thought of this until you pointed this out.
Is it just one question or one question per?
Just the one question. Here is the wiki on this riddle: https://en.wikipedia.org/wiki/Knights_and_Knaves
He’s lying, he’s not sorry.
What if G1 is lying and both of them always tell lies?
Or the “only” part is the lie?
