The best strategy would be to take some time off if you are on a losing spree, you will usually get a way better result after some break and will have better chance of winning what you lost back, it happened to me too many times and no matter how hard I try after a while I find myself making this mistake again but I'm noticing that I'm definitely getting better at it.
It's actually more on how you can control yourself better rather than winning more in case you reset your mind after a losing streak. It's like removing the impulsive desires in your mind, clearing it so as when you once play again, you can make better decisions in terms of exiting or continuing gambling.
Or simply stop getting all those losses back,
As OP said, he tried to gamble more instead of stopping immediately. He might thought that if he continue to play he might win that time. In this kind of situation, it is better to stop and try again the next day or a few more days before starting to gamble again.
True, trying to judge whether to stop on something as vague as luck on whether to continue or not seems like a bad idea. As far as it's concerned, it's actually one of the reasons why people seem to actually continue gambling even when they lost huge amounts, probably because they won big at the beginning. I don't know if it exists or not, but there are some casinos that let you win for a bit, then make you lose by quite a lot. Could happen in table games, yes possibility is low, but it could still happen right?
