Great blog. Your tutorial on the Push-off Double was excellent, and you are very adpt at the move, I have only seen a handful of magicians do it well. Though admittedly, it is much harder to do under fire than at home on your couch.

I learned the move about a year ago, mainly from Steve Draun’s “Secrets Draun From Underground”, p.14 Stud Two-Card Pushoff Lift. The only difference is the way Steve’s thumb is cocked to the side, which is also the way Kalush and Blaine do the lift… however, I feel this looks awkward and I modified the push-off to look more like yours. The stud-type turnover is also a big difference, and is mainly the way I turn the double over, but sometime I just flip it book-wise, as you do.

The most important tip is on p.16 “With practice, you will already have felt whether you have two or three cards. If you (happily) have two cards, then ignore the step described in this paragraph and proceed to the next, otherwise, with a light downward pressure by your right hand, your left thumb continues to push the block of three cards to the right. The block is dragged over your left fingertips. They (the left fingertips) will hold the lowermost card in place, freeing the double to continue moving (fig.5).”

This is very similar to you saying the left middle finger is the most important part of the push-off. Sometimes, when I am lazy or the deck is in poor condition, I just do a pinkie count then push off the double, that way it is 100% sure fire.

I hope this helps with your credits, I have a few more sources too if you are interested. Keep up the good work!
