The description of this trick is bogus. It claims "NO equivoque!" but the whole thing is one big
equivoque. The claim is, the spectator calls a number between 1-52, which matches your written
prediction, 100# of the time. Except, that's a lie. Don't trust the performance video. It works that
smoothly (without equivoque) literally 10% of the time. The other 90% of the time, it's all
equivoque. The instruction video is a sloppy mess. He makes mistake after mistake and never bothers
to correct himself. It includes no written cheat sheet for the complicated equivoque system, you
have to write it out yourself. At one point he counts wrong, doesn't know his own trick well enough
to notice. You can't return a magic trick, which Shin Lim exploits. I salute his skill, but the
description of Think is just phony baloney.
