Most smart players have a LOSING STRATEGY, meaning that you have a certain amount that you are prepared to lose and then stop gambling. It is smart to limit your loses. But you also need a WINNING STRATEGY. You need to decide an amount that if you win that much then you stop gambling and are able to walk away with your winnings. Why do you need a WINNING STRATEGY? The longer you play, the more likely that at some point you will hit your losing amount and quit. That is what the casinos count on. The casinos only win when you walk out a loser and if you don't quit while you are ahead the more likely it is that you will be a loser.
