You cannot win gambling when you don't have a self discipline, a self control. In one game you just have to be a formal Player to get the best move. If you have it all I'm sure people get luck every turns to wins.
No matter how good our skills, if we cannot control the emotion, then we cannot win in gambling. But if we can do this and when we can win the game, we can stop the game. But this will be difficult to do especially if we still want to chase the money from another game. Sometimes, when we win the game, we want to move to another game, and we want to know how good our luck in other game. But we don't know that we still have luck or not, and this can make us get another loss from the other game.
