This is a variation of the classic push off second deal where the thumb works from the top edge of the package rather than the long side edge of the deck.
The Movie Second Deal is really more a flourish than a second deal. It is a one-handed second where you pull out the second card and place it on top with the thumb.
The strike bottom deal is less versatile and needs a lot of practice to get right. It can be performed from an Erdnase grip or a standard mechanics grip.
Allan Ackerman invented this Put-In-Place (or PIP) bottom deal where the spectator is left with a very clean visual which seems to rule out a bottom deal.
'Minus one' means that you do not deal the bottom card but the second from the bottom - sort of a second but dealt from the bottom. This is an Allan Ackerman invention and uses a push off bottom technique.
The center deal is a tough move. This strike center deal is probably one of the easier ways to achieve a center deal. Using this deal Allan teaches a center deal demonstration where you only need to deal one card from the center and the rest comes from the top - making it a lot easier to perform.
This is a well thought out Dai Vernon version of the Glide. Every finger position and movement has its reason. The Glide is not necessarily the most deceptive move, but it is easy to do. This version is very deceptive. As is so often the case, Vernon elevates a simple move to a masterpiece of deception.
