Hmmm, at first glance I actually think you have that backwards.
Given that house edge exists, the longer you play and the more you bet, the more likely you are to lose. I've always argued that the smartest (although least entertaining to be sure) way to gamble in vegas would be to take ALL of your bankroll, bet it on a single hand of blackjack, and then walk away regardless of the outcome.
