For me, the very smart way to play gambling is to understand the game. Gambling is not just playing it, if you do really want to gain something from it, you must have to understand how the game is being played ( rules, instructions and etc.) I really do believe that gambling is dependent on luck but sometimes knowing the game could give an advantage
Do not forget the fact that it is also smart if we know our limitations. Gambling is really not just all about it, we do have to consider that we are using money in playing and sometimes we bet too much. We do not want going home without a single money nor a single penny in the pocket. Knowing your limitations, setting up limitations rather is also playing smart in gambling.
