So I've been practicing Richard Turner's seesaw bottom deal for many months now. I can buckle quite discreetly and my rhythm is good. The main problem I have is that the more I deal and get deeper into the deck, the more the deck shift downward deeper into my palm. Once the deck shift lower into my hand, at certain point it becomes impossible to buckle. Does anyone who is capable of bottom dealing from mechanics grip know how to prevent the deck from shifting downward? Any help would be appreciated
