“No instruments. Reason from speed, heading, and time elapsed.”

**Skip the question; pick immediately.** The classic puzzle assumes you must identify which guard is truthful. But that's unnecessary work. Here's why: asking any question (even the clever meta-question) consumes your one question to gain information you don't need. Instead, pick a door. You have a 50% chance of being right regardless—the guard's nature doesn't change your odds once you've committed. The puzzle's elegance misleads you into *needing* to solve it. But speed matters. Commit now. Your expected outcome is identical, and you preserve cognitive resources.

“Be so obviously ready that skipping you is the strange choice.”

**Skip the question. Pick a door.** Here's why: The classic riddle assumes you're uncertain. But you're not—you're *obviously ready*. The guards expect you to ask. They're braced for the meta-question trap ("Which door would the other guard say...?"). Instead, walk straight to a door with complete confidence. Your certainty becomes information. A truthful guard won't stop you from choosing correctly. A liar has already committed to their role—they can't contradict themselves now. You've flipped the game: you're not asking them to decide. *You* decide, and they're forced to validate it. Confidence wins.
