Gamblers always have an interest in their mind if they place a bet to increase their chances of winning. They will try again and again because there is no guarantee when that victory will come. I do it myself where even on the last bet I think I might win that bet but the result is not always the same. But what I have learned from this is that in gambling a gambler must refrain from chasing. The more the gambler chases, the more he loses. And there is nothing to say about the last bet here. As long as a gambler cannot control himself, his tension will be high.
By trying again and again, they only make their losses become bigger without they realize. That losses can turn to become a bankruptcy and make them lose everything.
We can not have a big expectation to win in the last bet because the situation can change at that time and I think many people already had this experience. So if we want to place a bet, we should not place a big bet especially if that is our last bet because we must prevent the big lose in the last bet.
Yes, we must refrain from chasing the win as that can make hard to control ourselves and gives more losses if we don't aware of that. He must hold his tension not to become high as that can make him lose control of his gambling activity.
