"you forgot that I left it on top, you replaced it with the image of me setting in the center"
This is all very confusing. You are telling them that they are remembering something that you never did! You never gave them the impression that the queen was left on top. You immediately gave them the impression that it was put into the center.
Your story may be that they are not mis-remebering, but rather not seeing what they think they are seeing. Therefore they are remembering a lie. You can play with this.
You may tell them that every time they try to remember what they have seen, they are wrong because the queen is on top. They are in fact remembering a hallucination.....now do the double, show the queen, turn face down, place card in center. But tell the audience NOT to remember. In fact when you ask them what happened tell them they should reply they don't remember. Play this up, get a strong response. Then show the queen on top and let them know that what they don't remember. never happened.
You can play many word games with the audience but you must make sure that every step is clear in the mind, not just physically but verbally.
Think of what Brad has asked you......when they audience walks away, how will they in short tell someone what just happened...he put the card in the middle, "I saw it" but it appeared on top. That is the essence of the effect and there must be no confusion.
And by the way, don't be upset with the answers you may get on this board. We are not professional critiques, we may not be able to write as a professor at college may right, but you are receiving answers form some of the best in the business.
