I did it sometimes and managed to save my bankroll from losses. Always on dice game with lowered odds to maximize winning chances. It was like a safe emergency bet for me, meaning that even if everything went wrong, I could still save my bankroll by following this strategy, and indeed it worked for a while. However, it's not a sustainable strategy on long run. Inevitably, at some point the all-in strategy made me waste the entire amount of money I could afford to lose, so it ended in loss, anyway.

I don't remember anymore how much profit I made while the strategy was working, because once you lose, all you want is to forget about everything...
In fact, it's not the kind of strategy I would advise someone to execute, because once it stops working, you will regret a lot for losing all your money in a single shot for nothing. Then you start thinking you could have used that money for longer, through placing smaller bets, and still having some chance to save your bankroll from total loss.
