In poker? Yes it is.
Casino game? Stupidity at its peak.
This makes sense.
I typically all in in poker when I think that I'm winning with the cards in my hands. But if I know that it won't make sense and have upperhand, I'll fold.
But in casino games, I don't think it's stupidity when someone does that. All-in doesn't mean that you should only do it with huge amounts but, if we have a remaining small amount of bucks, we could all in with that as well.
Going all in can still work if you got the less likely cards to win because you don't have to win, all you need is to make everyone on the table that you're winning and that's what I call it as an actual strategy.
But in casino it's just random so going all in just taking a leap of faith without even knowing what will happen.
Randomly in casino games is like betting all because you have to go.
But in poker, you've got the confidence of doing an all in because you know that your cards are about to win and you are the strongest for that time.
It is a strategy to also bluff, only you know it if you're bluffing.
