It All Depends By Eric Richardson

The world of memorized deck magic is a microcosm of the card magic world; it has specialists and enthusiasts who are experts on particular facets. Eric Richardson is an Aronson stack enthusiast, and he has made a host of interesting discoveries, all collected in one book and offered exclusively on this website.
The tricks in this ebook (over twenty tricks, 111 pages) are all specific to the Aronson stack. The good news is that, oddly, you don’t even have to memorize the stack to take advantage of these tricks. They work automatically, and the stack takes care of everything for you. For this reason, it makes a fun companion as you are learning the stack.
Mr. Richardson has discovered many new and unexpected things that exist in Aronson stack: he deals with Ace locations, cutting Ace routines, prediction effects, and more, and each one begins AND ends in Aronson stack. That’s convenient if you don’t wish to destroy the stack with each performance.
Aronson started this trend of tricks that simply work from the stack in Try the Impossible (see chapter called “Unpacking the Aronson Stack”), and Eric expands upon and extends this line. It makes for great reading, particularly if you are learning Aronson’s stack. And at ten bucks, it’s a good value and resource.
