Please spell it out

Basically, the prisoner should ask “what would the other guard say is the door to freedom?” Doesn’t matter which guard he asks, the result either way will be that the death door will be indicated. The door to freedom is the other one.

If the prisoner happens to address the truthful guard, the truthful guard will indicate the death door because that is the one that the lying guard would indicate.

If instead the prisoner addresses the lying guard, the lying guard will also indicate the death door. The lying guard knows that the truthful guard will indicate the freedom door, but of course the lying guard has to lie to the prisoner.

Google has many results for ‘two guards riddle.’ Similar to ‘twin brothers riddle.’ The earliest version I can remember revolved around twin sisters living in a remote place by a fork in the road. Couldn’t find that one quickly. And I forget which variation was in the movie.
