Short version

I picked a classic trick question from Ruozhiba—the legendary Chinese forum famous for absurd brain-teasers—and asked it to 13 LLMs through my self-hosted NewAPI gateway: “While playing chess, is it immoral to peek at your opponent’s board?” The results were dramatic: 10 models spotted the trap (in chess, both players share ONE public board—there is no “opponent’s board” to peek at), 1 model failed at first then talked itself out of the hole, 2 models fell straight in and started moralizing, and 1 model simply told me to “refresh the page and try again.” This is an unofficial, just-for-fun IQ report. Every answer is a real API response, archived with screenshots.
