Lets see...to explain this in the easiest way possible?
Since you're new to this deck, try this...
Separate your cards into "piles" by their suit.
Square up one suited pile and use your "stripper" move to slide the cards apart. If they strip with cards going in both directions, rotate one "side" 180deg. to match the other. That's it...when correctly oriented, the suited pile won't separate when you try to strip it.
Repeat for the other 3 suited piles.
Then, combine the different suited piles in the same manner and you should be done.
Good luck!
