Turning Tri-Cut
From dealing position,
shift the index and middle fingers counter-clockwise around to the
position shown in Figure 2-23. The index finger is now at the left
long side of the deck, the middle finger is at the far short end,
and the ring and pinkie fingers are at the right long side. The thumb,
from its position at the near short end of the deck, stretches to
the right and riffles down the near right corner to break the deck
one third of the way down (Figure 2-24). Insert the thumb into the
break to a depth of one knuckle (Figure 2-25), and swivel this top
third of the pack clockwise to the left (Figures 2-26, 2-27) until
the packets clear (Figure 2-28). Next, swivel the thumb packet slightly
back to the right and deposit it between the very base of the thumb
and the very base of the index finger (Figures 2-29, 2-30). Now stretch
the thumb to the right again and break the remainder of the deck in
half in exactly the same manner as with the first third of the deck
(Figure 2-31). Draw this new packet clockwise to the left with the
thumb (Figures 2-32, 2-33), until the packets clear (Figure 2-34).
Swivel the top two packets slightly back to the right (Figure 2-35).
Remove the index finger from between the packets as you close the
fingers and thumb together (Figures 2-36 to 2-38).
