I just want the Buck's tips on the Deck Flip.
There are three things I usually see people doing wrong with a deck flip.
1. They don't squeeze the pack tightly enough before the flip. Air in the deck will separate it into a flurry of individual cards.
2. They don't release quickly enough. You really need to
snap the hand open and back, so when you release the deck it doesn't touch any part of your hand; imagine that the deck is hot, and you're trying not to get burned.
3. They start the flipping motion too late. There's a flow to it, where the deck just flips itself when you let go of it, and that flow begins very early in the deck-tossing process; for the geometrically minded, it's a wide elliptical path with a narrow vertical radius. Do it
very slowly, and you'll automatically stumble into it because it's the only way you can do it at all when you slow way down.
These aren't Dan and Dave's tips, obviously, but I've been flipping stuff around as a nervous habit for years, and there's not much I
can't tell you how to flip from one hand to another in the air. Knives are the hardest.
