I know I shouldn't but I just love playing Blackjack at the casino. No I don't have gambling problem, but if I lost I could lose big. The thing is, most of the time when I play blackjack, when I am winning, I will chicken out and quit when I'm 150-200 bucks ahead.
But when I'm losing, I suddenly have the nerve to bet big. This is very wrong philosophy I know, but it's hard to control.
So yeah, when I'm losing big time (very bad luck), I could lose between 1 or 2 grand. And that's from something like 25-50 dollars table. Funnily, when I bet in a 100 dollars table BlackJack, I usually win. Go figures. But I don't have the nerve to stay in 100 bucks table for a long time.
But Blackjack also depends A LOT on the people around you. You got one stupid-ass player, he can pretty much F--ed you up. Maybe that's why it's easier to win at higher bet tables because at least you know that everyone knows what they're doing. Nothing worse than when dealer got a 6 or something, and then you got 2 same cards, you split, got good hands on both (or might even double on one hand) , and then some stupid guy at the end of the table hit the picture that we want for the dealer.
