I'm taking JMorgan up on his suggestion. Here's my opinions on Cellini's "mistakes", #4, 5 & 6-

4.Player retrieves his bet after a shuffle.
A mistake. It's a common one, too, and it can make a casino suspicious all by itself.
My verdict- a mistake. Snapable.

5. Player shows inordinate amount of interest in cards.
It's natural to watch the cards as payoffs are being made. What else are you going to do, read a book? If a player goes to extremes to see the cards, then sure, that's an alarm, but going to an extreme about ANYTHING will cause alarm. His advice to move your eyes instead of swiveling your head is very good. But merely watching cards won't cause a casino to snap. Depends on your definition of inordinate, but my verdict is- a tell, not a mistake, unless you are REALLY obvious.

6.Player orders non-alcoholic drinks.
Oh, come on! This is a classic example of my beef. This will NOT raise alarms all by itself. This will NOT cause a casino to snap. Sure, most advantage players don't drink booze while playing. And drinking booze (or successfully pretending to do it) is good camoflague. But this is merely a minor tell, something the casino would notice only if they are already watching you anyway.
Verdict- a tell, not a mistake. Won't cause a casino to snap all by itself, no way.
