I don't understand about smart way in gamble. What I understand is that when I get a profit, I get out of the casino. Then drink a beer at my subscription shop.
Play as much as you can when you lose. Do not get over that, and when you've made a profit. Take a break. Define target.
Smart way simply mean to not to put the situation on your nerves dont get too excited or dishearten by any of your move or the opponents. When you realize that things are going against you just relax get something for yourself to drink and stop by the time before you go for overspending your budget.
