Maybe you don't really need special training to gamble, when you gamble you only need to control your emotions because it won't be good to gamble in an emotional state, your opponent will easily defeat us. Play calmly and with the ability of our money to have, do not play outside the limits of the money we have it will be very disturbing concentration. Of course we all know that gambling in any form will not be separated from luck.
so controlling the emotion is the best practice for gambling. I think it's true because, on the gambling game, we cannot see clearly about the game itself and only greed because we can win the game easily and we want more winning to get more money. but the other things that we need to keep practice is how we can limit the money we use in gambling game so we don't have to lose much money without we realize and because of we are curious about why we cannot win in any round.
