So I've memorized the Tamariz stack. I've got a basic push-through shuffle, a false overhead shuffle, and a couple of false cuts.

What other slights should I learn for working with the deck?

What are some of your favorite effects with a memdeck?

Obviously card calling is very popular and very hard-hitting.
Juan Tamariz's book 'Mnemonica' has some great tricks (and some 'so-so' tricks) with the memorized deck. Do you own that?

Yea I've been flipping through it. There is some good stuff in there, but I'm not blown away by anything I've read yet. It might just be his style of describing the effect that leaves me feeling that way though; he's very sparse in his descriptions.

What do you mean by card-calling?

The best effect I've been able to produce with it is simply a very clean peek. I use a 3-3-2-2 count as I spread the cards between my hands, so when they select a card I know what it is. It leaves them convinced that there's no way I could know their card.

Basically, card-calling is this: Spec removes a block of cards from the deck; performer names all of the removed cards. It's one of the most basic stacked/memorized deck effects there is. You can find one example on Richard Osterlind's Mind Mysteries DVD set; it's one of the routines using the BCS.

I don't have this myself, but I hear it might be worth looking into: Simon Aronson's work. He has a lot of work on the memorized deck.
