The Knight's Tour Revisited by Lew Brooks and Steven Keyl
Many years ago, as a young chess player, Mr. Lew Brooks was impressed by watching a knight's tour performed on a chessboard as a pure demonstration of memory. Many mentalists and memory experts have employed this stunt in their acts.
Some memory experts also perform a version of memorizing the order of a deck of playing cards in a very short period of time. 

The concept of combining the Knight's Tour with a memory stunt is not new. Bob Cassidy combined the Tour with a magic square in his 2003 ebook release "Mind Explosions." To our knowledge, however, this is the first time the Tour has been combined with the apparent memorization of a deck of playing cards.

From the accompanying .pdf file, "My idea was to combine these two independent procedures into one mind blowing and almost impossible feat of concentration. Because I do not possess the raw ability to actually do it, I needed to develop a way to be able to appear to be performing just such a massive endeavor. The Knight's Tour Revisited is my solution to the problem."

"What you have in this work is the most amazing, unbelievable, reputation making demonstration of memory and extreme concentration available anywhere today." -Lew Brooks

"This is without a doubt, the greatest display of mental agility and cognition that has ever been, or will ever be, devised." -Steven Keyl

Bob Cassidy raves, "...the concept of doing the "tour" and a memory demonstration at the same time is not new."
