Most places will freeze you out if they suspect you're counting. You won't be able to step foot in any casino if you get flagged.
Playing perfect strategy is legal, counting cards is not. Blackjack is way to stressful in my opinion. I've been yelled at by the person to my left for taking a card that would have busted the dealer.
Yeah, no thanks, mini-bac, craps or hold'em for me.
