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.
I do not think playing as much as you can without planning is a smart gambling. Everything should be set in the plan before gambling. Keep on focus and have track of the time. This means you are aware of your environment and everything that is happening. If you feel like you are having a bad time then don't be shy on quitting and playing another day.
