No doubt many wrong decision in gambler is as result feeling on can beat a casino after wining the first time, I was once a victim where I lost multiples of what I win as result of high expectations of wining more than what I have won before and constantly trying to beat they casino, the best a player can do. Is to take a break after winning or else the casino will drained your pocket if you don't have control.
Gamblers often make wrong decisions emotionally, so that later they have to suffer the consequences of that wrong decision. I have seen many gamblers who perform well one day, then they keep gambling all day, so that their pockets become empty at some point. So the gambler has to have an estimate of his own ability, so that he doesn't get overconfident and influence himself in the wrong way. So I think when a gambler can control himself, he won't take aggressive steps to beat the casino.
