(What caused me to give up was an extremely expensive blackjack hand that started with betting $HOUSE_MAX on a hand, and getting a pair of aces. The best move is to split aces, resulting in two hands, at double the bet. And in this case, both those hands were then facing a dealer hand where basic strategy demands that you double down - so an already significant bet ended up being doubled, then doubled again. It was absolutely the right move, statistically, but didn't go my way in the end, and although I still walked away in profit, that hand is what made me think that Blackjack was something that could one day cause me a real problem if I didn't find something better to do with my time.)
So I guess it depends on how much $HOUSE_MAX was. Around here the Indian casinos are atwitter at $100 bets. In Vegas I could be playing with a bunch of $10 players and nobody bats an eye if someone walks by and, in the middle of a deck, bets $1000 on a single hand, and then goes on his way.
Great documentation as well. I'll definitely be referencing this.
