I tried yesterday to do riffle force for my friend and he said "I didnt say stop in that spot!" I tried it again and same result. Then i put my force card on top of the deck and placed his card above it. Then i did a double lift and that worked.
Later i did Biddle trick for him and after 10...
I keep notes of my tricks and flourishes in computer. I also wrote my tricks in my cellphone because i realised that i never remember my tricks. But cellphone is always with me.
I have Jeff Wesmiller's Weapons of the card shark 1 & 2. You learn almost everything you need. Second dealing, bottom dealing, false shuffles and cuts, stacking, deck switches, glimpses and everything... :cool:
