Counting cards in black-jack is really a way to increase your chances of winning. If you’re beneficial at it, you are able to really take the odds and put them in your favor. This works because card counters increase their bets when a deck wealthy in cards that are advantageous to the gambler comes around. As a basic rule, a deck wealthy in 10’s is better for the player, because the dealer will bust more generally, and the player will hit a black-jack a lot more often.

Most card counters keep track of the ratio of good cards, or 10’s, by counting them as a one or a – 1, and then provides the opposite 1 or – 1 to the low cards in the deck. Several systems use a balanced count where the amount of low cards will be the same as the amount of 10’s.

Except the most interesting card to me, mathematically, could be the five. There had been card counting systems back in the day that involved doing nothing much more than counting the amount of fives that had left the deck, and when the 5’s have been gone, the gambler had a massive benefit and would raise his bets.

A very good basic system player is obtaining a 99.5 percent payback percentage from the casino. Each 5 that’s come out of the deck adds point six seven % to the gambler’s expected return. (In an individual deck casino game, anyway.) That means that, all things being equal, having one five gone from the deck offers a gambler a little advantage more than the house.

Having two or three 5’s gone from the deck will really give the player a pretty considerable edge over the casino, and this is when a card counter will usually increase his bet. The difficulty with counting five’s and nothing else is that a deck lower in five’s occurs fairly rarely, so gaining a major advantage and making a profit from that situation only comes on rare situations.

Any card between two and 8 that comes out of the deck boosts the player’s expectation. And all 9’s. 10’s, and aces improve the gambling den’s expectation. But eight’s and nine’s have very modest effects on the outcome. (An 8 only adds 0.01 percent to the player’s expectation, so it’s usually not even counted. A 9 only has point one five per cent affect in the other direction, so it is not counted either.)

Understanding the effects the reduced and great cards have on your expected return on a wager may be the initial step in understanding to count cards and wager on black jack as a winner.
