Card Counting in black jack is a method to increase your chances of winning. If you’re excellent at it, you’ll be able to actually take the odds and put them in your favor. This works because card counters increase their bets when a deck wealthy in cards which are advantageous to the gambler comes around. As a general rule, a deck rich in ten’s is much better for the gambler, because the croupier will bust far more usually, and the gambler will hit a pontoon much more often.

Most card counters keep track of the ratio of superior cards, or 10’s, by counting them as a one or a – one, and then gives the opposite one or – one to the low cards in the deck. Some techniques use a balanced count where the amount of low cards could be the same as the amount of 10’s.

But the most interesting card to me, mathematically, is the 5. There were card counting systems back in the day that required doing absolutely nothing more than counting the quantity of fives that had left the deck, and when the five’s were gone, the gambler had a huge advantage and would increase his bets.

A very good basic system gambler is getting a 99.5 per cent payback percentage from the gambling house. Every five that has come out of the deck adds point six seven percent to the gambler’s expected return. (In an individual deck game, anyway.) That means that, all other things being equal, having one 5 gone from the deck provides a player a smaller advantage over the house.

Having two or three five’s gone from the deck will actually give the player a quite substantial edge over the casino, and this is when a card counter will usually raise his wager. The issue with counting five’s and absolutely nothing else is that a deck low in five’s occurs quite rarely, so gaining a large advantage and making a profit from that scenario only comes on rare occasions.

Any card between two and 8 that comes out of the deck raises the gambler’s expectation. And all 9’s. 10’s, and aces increase the gambling den’s expectation. But 8’s and nine’s have very smaller effects on the outcome. (An eight only adds point zero one % to the player’s expectation, so it’s generally not even counted. A 9 only has 0.15 per-cent affect in the other direction, so it is not counted either.)

Understanding the effects the minimal and superior cards have on your expected return on a bet will be the first step in discovering to count cards and wager on twenty-one as a winner.
