With this technique, a card is switched as it is removed from a face-up, in-the-hands spread and placed face down onto the table. The switch seems first to have been created by Roy Walton, who published it as part of his seminal routine “The Collectors” in Abracadabra, Vol. 47 No. 1203, Feb. 1969, p. 99.

It has been reinvented several times and has been published under the name “Simplex Switch” (Karl Fulves, Mexican Monte, 1972, p. 27), “The Kaps Switch” (Roberto Giobbi, Card College, Vol. 4, 2000, p. 816, in German language in 1994) and the “Two Card Take” (Bruce Cervon in “Really Wild” in the May 1972 issue of Genii [Vol. 36 No. 5, p. 230], where he did not name or explicitly claim credit for the switch; but later does so in “Nowhere and Everywhere” in the May 1990 issue of the same journal [Vol. 53 No. 11, p. 729]). Still other reinventions of the sleight can be found.
