I think I've gone all in and won before, but that's just a guess. You should never go all in. It's only a last ditch effort that should be used with caution. Even if you all in with 90% chance of winning, there's still a chance that you can lose your money.
I agree with you. I tried to go all in in my first round of play with 95% chance of winning and I lost. Well, you really have high risk in gambling.
No matter chance what you play, even if you play the maximum chance. If indeed you are destined to lose. Remember the house always wins. I just hope you thinking twice before doing it
