I think that Erdnase has a lot to teach us about executing a shift at the card table. You have to piece together bits from various places in the book to get the full picture, though. I believe that a thorough reading of the description of the "Bottom Palm, When Cards Are Riffled", the "Shifting the Cut" section, the description of the SWE Shift and, of course, the descriptions of all the Card Table Artifice shifts will provide a substantial quantity of food for thought as regards getting into, executing and getting out of a shift at the card table.
