no there is no force, but one question i could never find out was whether the deck could be examined.
Since I have Andy's book SPAM, I know how the original routine works. I even found a way to do it without the Code. But now I'm very interested in that application, and it will probably be the reason why I'll buy the Code.There is no forcing and no sleights involved in any way. In some applications, the deck can even be shuffled (by the spectator!) before, during, and after the performance. That's perhaps my favorite application of The Code - a contribution by Steve Cohen.
