I've never played "team" blackjack so I have no idea on what are sucker signals and what works well. I'm not worried about our cover since I'm a mid-30's white-chick and my sista is in her 50's. I'm a geeky card counter and she likes to play by instinct.
But I am worried about her staring at my pinky or using a lame verbal cue. I don't even know where to start to think of a que.
Any tips or recommendations on a book that covers this topic well?
Thanks!
