(this is NOT by me)
I give credit to Mikkel Samuelsen, and twin brothers Dan and Dave Buck for this.
I will show step by step photos and explanations. Good luck!
Hint: It's easier than it looks (not saying too much but still...)
Step 1: Grip
Picture 1: Ensure you hold the deck EXACTLY in this position.
Picture 2: You should be able to do that.
Picture 3: The starting grip.
By the way, look for cards that fit your hands. It's much easier for learning. When you are done, you can use larger cards (like title pic).
Step 2: First Pull
Picture 2: Lift middle third in a zig zag. Note bottom third is cluched between left index and pinkie. Also note it is the 6 of hearts.
Picture 3: Swing bottom third away (you can just see a bit in the photo) and place left thumb on the middle third.
Picture 4: Split the middle in half. Now there are 4 parts (looks like original three but this one is the 2 of hearts). Other part is still barely seen (still between the two fingers).
Picture 5: Swing 3rd part (from the top) towards you. Note the 2 of hearts is BELOW the 2 of spades.
Picture 6: Swing right hand away from you to swing the cards even further out. Also note that I'm pushing the 10 of diamonds (only one card) with my right index, pivoting on my right middle.
Picture 7: Note that the 2 of hearts is ABOVE of the 2 of spades. The finished First Pull. If you have come this far then you're doing well.
