Lets say you can count cards. But you don't want to increase your bet to keep eyes off you. So lets say you simply left the table when the count got bad, then came back when they reshuffled the deck.

First question is - would this give you some kind of advantage over just playing consistently? I would have to think it would.

Second question - if this would give you an advantage, do you think a casino would ever really care?

Third question (which maybe answers the second one) - how much of an advantage could it realistically give you? Enough to potentially overcome the house edge?

Thanks!
