Five’s in Blackjack
Wednesday, 10. November 2010
Card Counting in blackjack is really a method to increase your chances of winning. If you’re very good at it, you can in fact take the odds and put them in your favor. This works because card counters elevate their bets when a deck wealthy in cards which are beneficial to the player comes around. As a general rule, a deck rich in 10’s is much better for the player, because the dealer will bust much more frequently, and the player will hit a twenty-one a lot more often.
Most card counters keep track of the ratio of good cards, or ten’s, by counting them as a one or a minus 1, and then provides the opposite one or – 1 to the reduced cards in the deck. Several methods use a balanced count where the variety of lower cards may be the same as the quantity of ten’s.
Except the most interesting card to me, mathematically, would be the five. There have been card counting techniques back in the day that required doing nothing far more than counting the amount of fives that had left the deck, and when the five’s had been gone, the player had a big advantage and would elevate his bets.
A very good basic method gambler is obtaining a 99.5 percent payback percentage from the gambling den. Each five that’s come out of the deck adds 0.67 per-cent to the gambler’s anticipated return. (In a single deck game, anyway.) That means that, all other things being equivalent, having one five gone from the deck gives a gambler a small benefit over the house.
Having two or three 5’s gone from the deck will really give the player a quite considerable edge more than the casino, and this is when a card counter will usually elevate his bet. The dilemma with counting 5’s and nothing else is that a deck very low in 5’s happens quite rarely, so gaining a large advantage and making a profit from that situation only comes on rare situations.
Any card between 2 and eight that comes out of the deck increases the gambler’s expectation. And all nine’s. ten’s, and aces boost the betting house’s expectation. Except 8’s and 9’s have really modest effects on the outcome. (An 8 only adds 0.01 per-cent to the player’s expectation, so it is generally not even counted. A nine only has 0.15 % affect in the other direction, so it’s not counted either.)
Understanding the effects the minimal and good cards have on your expected return on a bet could be the first step in learning to count cards and bet on black-jack as a winner.
