Card Counting in blackjack is really a way to increase your odds of winning. If you are very good at it, you’ll be able to basically take the odds and put them in your favor. This works because card counters elevate their wagers when a deck wealthy in cards which are beneficial to the player comes around. As a general rule of thumb, a deck rich in ten’s is much better for the player, because the croupier will bust more frequently, and the gambler will hit a blackjack a lot more often.
Most card counters maintain track of the ratio of high cards, or ten’s, by counting them as a 1 or a minus one, and then provides the opposite 1 or minus 1 to the lower cards in the deck. Some systems use a balanced count where the amount of very low cards would be the same as the quantity of ten’s.
Except the most interesting card to me, mathematically, is the five. There have been card counting systems back in the day that included doing nothing more than counting the amount of fives that had left the deck, and when the 5’s were gone, the player had a big advantage and would raise his bets.
A very good basic system gambler is acquiring a nintey nine and a half per cent payback percentage from the casino. Each and every 5 that has come out of the deck adds 0.67 per cent to the player’s expected return. (In an individual deck game, anyway.) That means that, all other things being equal, having one five gone from the deck offers a gambler a small advantage more than the house.
Having 2 or three five’s gone from the deck will really give the gambler a fairly considerable advantage over the betting house, and this is when a card counter will usually raise his bet. The difficulty with counting 5’s and nothing else is that a deck very low in five’s happens quite rarely, so gaining a huge benefit and making a profit from that situation only comes on rare instances.
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 boost the gambling establishment’s expectation. But eight’s and nine’s have quite little effects on the outcome. (An eight only adds point zero one percent to the gambler’s expectation, so it is typically not even counted. A 9 only has 0.15 per cent affect in the other direction, so it is not counted either.)
Understanding the results the minimal and superior cards have on your anticipated return on a wager may be the initial step in discovering to count cards and wager on blackjack as a winner.
