Chris Capehart did two card tricks for Penn & Teller this season (10) in episode 14. The second card trick Chris performed is the subject of my topic. If you haven't already seen Chris's performance, you can watch it here (the link should queue you up to the start of the second card trick):

I already know how Chris did his trick. What I'm curious about is if this effect has ever been published anywhere? Has anyone seen someone else perform this effect or seen it in a book or DVD? If so, name of the effect and who created it? Source material (if you know).

Please and thank you!

I believe, but not sure, it's Terry LaGerould's Countdown Force. If it is it was published in Nick Trost Subtle Card Creations vol. 2 and probably in one of his books.

I could be wrong so wait for some other replies.
