Being a surveillance manager for a casino i have lots of experience with this.
What you already now about cards moves can be used in cheating. The way I've always put it is that: When it comes to the moves card cheating and magic are the same, the difference is the presentation you put into the moves.
Check out the "at the card table" series by Darwin Ortiz, or any of his material. A lot of his stuff is "gambling oriented" routines.
Anything by Richard Turner would do you good.
Steve Forte Gambling Protection series is probably the best series out there right now on "gambling protection". Steve Forte is a master at cheating all casino games. They sell for $25 each and are 4 to the series, and are only on VHS now. Supposed to be on DVD this year sometime.
George Joseph has a couple of DVDs you should check out, "cheating at blackjack" "cheating at Gin" "cheating at craps" Cheating at Poker" and "cheating at Backgammon"
The Sal Piacante "poker cheats exposed" DVD set is also good.
But as said before get "expert at the card table" Learn the moves in there you'll get most of what you need for cheating.
as said before Stay away from weapons of the card sharks, stay away from Brian Tudor stuff for cheating.
Finally check out the gamblers book shop at
www.gamblersbook.com , this is the ultimate repository for DVD, VHS, and Books on all things gambling, from how to play, deal, and cheat almost every game out there.
Hope this helps
