Huh? The solution doesn't require you to "IGNORE EVERYTHING YOU KNOW ABOUT CHESS RULES". I can't speak for all casual players but this is a rule that seems technically possible but just never executed because it's hard to conceive a situation in which it would ever be used in practice. For those of us who don't know this specific rule, there's no excuse for us not thinking-outside-of-the-box...and learning of the "solution" is enjoyable.

Life is full of rules in which the exception was never addressed or outlawed because the exception was never even considered. [Insert Kobayashi Maru trope here]
