A gambler who is not well experienced with gambling and the risks involved with going all-in on a bet or game should never try it, except the person is concious of this decision and had made up his or her mind to take without any form of regret, whatever be the outcome of that decision.
They're players who, I've read time to time on Quora, suffering from the addiction of going all-in. To me, it's the worst form of addiction stories I've ever seen. And at what length would it take the gamer until they begin to trace back down the road of responsible gambling. The syndrome all starts with the save time mentality, trying to go all-in and see whatever the result is win or lose then move away.
Since they assume that spending 1 hour in a casino and leaving empty is also as good as staking everything all at once and go out a loser. This idea seeps into and poisons the very experience of gambling. Thereby restructuring the gamer into a shocking and hardly irreversible gambling frame of mind.
