Devised about six years ago, this is an improvement on the Erdnase
diagonal shift palm. Others may have discovered similar moves but have
never described anything quite the same. The steal can be accomplished
with everyone watching your hands — if they are that kind of people, YET
IT IS POSITIVELY INDETECTABLE!

If a card has been chosen, riffle the deck for the person to return it, but
squeeze at the inner end so he cannot force his card in all the way. It
should protrude about half an inch, or as much more as you like, from the
outer end of deck.

In any event, whatever the trick, you let project in this way whatever card
is being inserted, and hold the deck in the left hand with the forefinger
bent under it, the thumb on one side, the remaining three fingers on the
other. Cover the cards with the right hand and immediately drop both
hands FROM THE WRISTS, so the outer end of the deck is towards the
floor. At the same time, push the protruding card to your left with the right
little finger, until it presses against the left thumb, then shove it diagonally
inwards through the deck with the right forefinger, until this card is also
pressing against the left little finger.

The left hand then releases the deck entirely, the left forefinger pressing
the cards into the right hand as it straightens out. The only parts of deck
now visible will be the corner X shown in illustration, and the corner
diagonally opposite.

The right hand holds the deck between the thumb around the corner X and
its third finger is near the outer left hand corner. As for the chosen card,
the right forefinger rests on corner A, and the little finger presses against
corner B so that corner C is against the base of thumb.

The left hand now takes the deck by gripping it at corner X between the
thumb and forefinger. The right hand remains stationary while this is
done, but its first three fingers straighten out slightly to allow the deck to
be removed. It will be found that the chosen card will be left palmed in the
right hand, securely held at corners B and C.
