Methinks yer missing PV's point
The point is that count systems, whether Hi-Lo or APC or KO or whatever, all rely upon one thing to get the odds into our (player's) favor.
Namely, it's the idea of betting more when the odds favor you, and betting less when they do not.
See, if you "flat bet" (bet the same amount all the time) then you never really do anything to take advantage of when the odds are in your favor.
A way of looking at it is like this. Imagine a BJ game like no other. There are only aces, 10's, Jacks, Queens, and Kings in the deck.
(WOW! Our dreamland! :) )
Okay, but seriously. Every hand is going to be either 20 or 21, right?
So we're playing along. In this dreamworld, we can see that the dealer and the player both have equal odds of drawing a 20 or a 21.
There are only a few outcomes possible in this dreamgame.
D gets 20, P gets 20, push.
D gets 21, P gets 20, dealer wins the bet.
D gets 21, P gets 21, push.
D gets 20, P gets 21, player wins [b]150%[/b] of the bet.
AHA! You can immediately see that if everyone has equal odds of drawing either 20 or 21, the player has a massive advantage, because when he wins, he gets MORE than the dealer gets when the dealer wins.
Okay, you say. But real-life BJ isn't like that.
You're right. The primary place that the house gets its money back lies in the fact that if the player busts AND the dealer busts, the dealer still wins the bet (since the dealer takes the bet immediately when the player busts).
That rule variation, plus all the other little changes to the game, make it such that the house has a slight advantage over the player. It's not a lot, but with several players at dozens of tables all playing several dozens of hands per hour, 24 hours a day, 365 days a year, we can see that even the small advantage winds up being HUGE for the house.
So. What are we to do about it?
Well, if we flat-bet, we never really get a chance to get back to that dreamland game. In the dreamland game, remember, the player's advantage is due to the fact that the player wins MORE money than the dealer wins. (The pushes wind up canceling out.)
So to get the player into the advantage, we "card counters" (or "advantage players) try to make it so that when WE win, we win more money than when the dealer wins.
And by whatever count system we use, we can figure out when WE have the advantage and are more likely to win.
So let's take another jump to dreamworld. This time, we're going to ignore the actual points of the hands, and only look at how likely we are to win. We're going to pretend this time that we know who's going to win each hand.
In 33% of the hands played, the dealer is going to win.
In 33% of the hands played, it's an equal chance as to who's going to win, or it's going to be a push.
In 33% of the hands played, the player is going to win.
Now, we know exactly which hands are which. How are we going to bet?
Well, obviously if we flat-bet, we're going to break even.
So the answer is that we're going to not play at all when the player is going to lose, and we're going to bet as much as we can possibly afford when we know the player is going to win, right?
Well, coming back to the real world, we can't do that. No casino with any brains at all would let us.
So the answer is that we must bet "as much as we can" during the games we think we're going to win, and "as little as we can" during the games we think we're going to lose.
How much is as much as we can, or as little as we can?
Well, that's determined by our bankroll, and by how much the house will notice or allow before they boot our asses out. :)
So when PV says that you gotta increase your spread, that's what he's talking about. The fact is that the amount we can spread is what gives us a large portion of our advantage over the house.
Your problem is that the minimum amount the house will let you play is too close to the maximum amount that your bankroll can really afford. Our advantage under any/all systems is so small that there's still a considerable risk of ruin if we were to bet too much; we have to have reserves for the inevitable times that we have the advantage, but we wind up losing anyway.
So I'd venture to say that your basic "next step" is two-fold. First, learn and perfect your system. You should know it cold, backwards and forwards. Second, develop a good cover. That will allow you to vary the bet more. Third, either find a game that allows a lower minimum bet (there's $5 mins all over the place, and in some places you can get a $2 min) and/or increase your bankroll to a point where you can afford to increase your spread.
Personally, I'm still in the first phase. I just figured out that we really can have a system, and we really can gain an advantage. So right now I'm in the midst of figuring out which of the local casinos have games that help me, developing my cover so I don't have a giant flashing "Card Counter!" sign on my chest when I play, and I'm working on my bankroll.
(Luckily for me, at least over you, I have a good job that pays a lot of money. Unluckily for me, I also have a mortgage, car, bills, a dog, and a girlfriend, all of which suck up the vast majority of the salary that is left after Uncle Same takes out the taxes. If it weren't for all that crap, I'd already have a mid to upper 5-figure bankroll! LOL)
Good luck,
