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.
At that point it is good that withdraw the winning and enjoy the life with it but how will a person play in secure so while playing he do not lose. For that I will suggest to not spend too much in gambling as it is not sure that you will win or lose so if you will lose then you will not feel heard broken and if you win then it will be better according to your luck some people even win a more nigger amount with lowest bet.
