I agree with all the above references and sources. I'll also offer a few "online lesson" classic pass pointers that can be found variously in the above-mentioned books and videos.
1. Hold the break along the right side, not at the back of the deck. The right fingers cover the breach in front (Krenzel).
2. Pull the top half of the deck to the right, i.e., across, rather than down.
3. You can jiggle, riffle, dip or do any number of things with your hands to hide the action, but just be aware that these actions draw attention to the hands, which isn't where you want attention to be. It's not wrong, per se, it's just something to be aware of.
4. One interesting illusion is that if you bow the deck, i.e., squeeze with the right hand so the deck goes concave, and then do the pass as you release the pressure, it hides the telltale flash of the lower-left corner without having to lift, tilt or dip.
And, of course, there's always the double cut. ;)
