I need help with forcing cards. I think the classic force is great... when I can pull it off. I struggle to get it every time and when I don't I have to do weird movements to get the card back. I use the riffle down the side force which works but seems sketchy to me and I do like the one in royal road called the lift shuffle force. I tried the classic force on my friend today and before he even pointed to a card he said "your trying to force a card aren't you?" All I said was point to a card. I tried the hindu force on my dad yesterday and he knew it was the bottom card. What do I do? Also are there any good dvd's or books about solely forcing cards (that are relatively cheap).
