Ok. . . you've made 3 total posts and your asking for a method. . . this makes old guys like me raise an eyebrow.
Firstly, I have two questions for you,
a.) Have you studied the foundation texts on Mentalism like Corinda, Annemann, etc.?
b.) Have you looked through the
Annemann 202 Forcing Methods booklet?
Yes, I have a method and it's one that's been around for a very long time though I've given it a few twists of my own. I've use it in Radio interviews and caused everyone listening to end up on the same "freely" chosen card . . . the rudiments of this force can be found in the Annemann book mentioned above and in Maven's
GREY ELEPHANT IN DENMARK routine. I emphasize, you will find the essence behind the technique that's used for doing what we're talking about here.
Another source is psychological in nature and not as certain as the above, it is based on the classic Magician's Force but is far cleaner and more deceptive. . . it is of course, a bit of "advanced" mentalism when it comes to the how it works side of things but it is easy enough to figure out if you're familiar with this classic handling and certain bits of business Banachek has been writing about over the past decade. . . I'll not take things further in that I believe in encouraging people to do some research on their own vs. handing them all they need on a silver platter; seems that when they have to dig around and earn the information, they respect it a lot more.
I have no doubt that someone will either post of pm you with a solution, magic forums are notorious for such things. But I promise you, the greater advantage for you is to not just setting on instant gratification - learn your craft.
