That particular issue of Magic magazine is not available anywhere that I can find and where is the video available at?

I saw the issue available at a German magic book shop. Ordered it immediately

I managed to track down a performance video of Yves Doumergue's "Ten for Ten" effect as performed by Joshua Jay on his L&L Talk About Tricks DVD set: https://www.youtube.com/watch?v=cB5YOrYWpbw

Thanks for posting the video. I like this effect.

Hi, Not sure if I know the working of the effect. However, here is a thought about not allowing the last 2 cards to go on the same pile. Proceed with the dealing of the second face down packet into 2 piles, but tell the person to stop when only 2 cards are left. Then state that the person has the option of turning either one of the 2 remaining cards face up and place onto the face up pile. Then the remaining face down is to be placed onto the face down pile. The option of choosing the face up and face down cards provides a reason to separate the cards onto the 2 piles. Naturally, this needs proper verbal instructions. Anyway, just a thought. Bob

I have this. If I get a chance today I'll look it over and explain what happens in the case mentioned.

Has he (Yves Doumergue) published the pamphlet/booklet in the meantime?
