I agree with Gronbog (save the earlier comment.) Streaks for and against the dealer are part of the random process but you will add to that length mixing in your typical "busts." The dealer and the players start with two cards each. With that it goes in as a 50-50 chance of who has the best card total. Obviously, if all cards are up your decision is mostly made. Nope one dealer card is down - there's the psychology "gain" of the game. So assume 10 in the hole? I already covered that off-based assumption in a previous post. For fun, lets say you have been dealt a "hard 12." Of the thirteen cards in a suit, four will bust you and four will not help you those being an ace, two three or four. So there are a total of eight out of thirteen; four where you give your bet to the house through a bust, and four that will get you to 13, 14, 15, or 16. If you get a "little" card, hit again? Restated, only five of thirteen will help and that goes for a hard twelve all the way to a hard 16. Consider the 50-50 going in though you are better off forcing the house rules on the dealer making your odds at least as good as counting. Flip a coin then. Yes there is a 50-50 chance of heads every time, however, three or four heads in a row and I'm betting tails and running that bet up until it happens. This isn't rocket science, it's numbers. All I'm saying here is understand and take advantage of them. It works like no other.
