Five’s in Chemin de Fer
Counting cards in blackjack is a way to increase your chances of winning. If you’re good at it, you may basically take the odds and put them in your favor. This works because card counters elevate their bets when a deck rich in cards which are advantageous to the gambler comes around. As a general rule of thumb, a deck rich in 10’s is better for the player, because the croupier will bust a lot more often, and the gambler will hit a black jack much more often.
Most card counters keep track of the ratio of good cards, or 10’s, by counting them as a one or a minus 1, and then gives the opposite 1 or – one to the very low cards in the deck. A few methods use a balanced count where the variety of very low cards would be the same as the variety of 10’s.
Except the most interesting card to me, mathematically, would be the 5. There were card counting methods back in the day that engaged doing nothing a lot more than counting the number of fives that had left the deck, and when the 5’s had been gone, the gambler had a huge advantage and would elevate his bets.
A good basic technique player is obtaining a ninety nine point five per cent payback percentage from the betting house. Each five 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 other things being equal, having one 5 gone from the deck gives a player a little benefit over the house.
Having two or three 5’s gone from the deck will actually give the player a pretty considerable advantage more than the gambling establishment, and this is when a card counter will usually increase his bet. The problem with counting 5’s and absolutely nothing else is that a deck low in five’s happens pretty rarely, so gaining a massive advantage and making a profit from that scenario only comes on rare situations.
Any card between 2 and eight that comes out of the deck raises the gambler’s expectation. And all 9’s. ten’s, and aces improve the gambling den’s expectation. Except 8’s and 9’s have quite tiny effects on the outcome. (An 8 only adds point zero one per cent to the gambler’s expectation, so it’s normally 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 results the minimal and good cards have on your expected return on a bet may be the first step in understanding to count cards and play black jack as a winner.
