I have seen a few performance videos lately, and I notice the same problem. In the video recently posted in the media section, the spectator guesses the final reveal before it happens. There is still a great reaction, but I think the presentation should be changed a bit. I didn't like Kenner's reveal where you show the card before the spectator can answer your question (What card is in the middle?) My problem with this is that I like to build up the effect more. But if you show the top card to be a 3 and the bottom card to be a 4, then ask what card is in the middle, most intelligent know that it is not going to be the 5, so they can guess the outcome. I noticed this during a few of my performances as well. So here is a simple performance change. At the end, show the 3 to be on top, then turn it face down, show the 4 to be on bottom (cards may be different this is just an example) and turn it face down again, leave the middle card outjogged. Quickly square the cards and do a little snap or magical gesture, then fan them out and ask what card is in the middle. This way they still think they are playing around with the 3, 4 and 5. The reveal of their chosen card is a real shocker. I do this now and the reactions are even more incredible. Hope this helps. Feel free to dissagree as well.
