A-5 info.
I too am somewhat interested in the ace-five count, but have only been able to find one article about it, which I have pasted below. What's strange is that the article gives the specifics for using the count in a six deck game, for which it is not considered to be effective. I would like to find the specifics for using the count in a single deck game; it supposedly gives you a .25% edge over the house in an average single deck game. Does anybody know where the specifics for using ace-five in single deck can be found? The link provided near the bottom of the article for Grinder's Blackjack Simulation Warehouse was dead. Here is the text from gamemasteronline.com about the ace-five count:
Simply put, the Ace-Five count recognizes the two most important cards in the game. The Ace is the most important to the player because it is the key component in a 'natural' Blackjack. Plus, it's a very versatile card to get, even if it's not matched with a ten. The five is the most important to a dealer (dealers' 'naturals' put aside for the moment) because it takes the 'stiff' hands of 12-16 which the dealer MUST hit and turns them into hands totaling 17-21. Clear with that concept?
Now, what can counting those cards do for you? If you keep track of the Aces by assigning them a value of -1 (minus 1) and track the fives by assigning them a value of +1 (plus 1), you'll know when there's an imbalance of Aces versus fives in the shoe you're playing. Think about it. At the beginning of a shoe, there are an equal number of Aces and Fives in the deck(s) to be played. If, in the first round, 3 fives are played but no Aces show, you know that for the second round, you have a better chance of receiving an Ace. That may or may not happen, but it's a percentage play and if you bet more money when there's a better chance of getting an Ace and less money when the shoe is neutral or 'poor' in Aces, you'll cut down the house's edge a bit. Just how much depends upon a lot of factors such as the casino's rules, the ratio between your low bet and your high bet, how well you play according to basic strategy and how accurately you keep count.
Here's a recommendation for a game which has six decks, double is permitted on any two cards including after splitting pairs and the dealer stands on A-6. The casino's long term edge over a player who uses the proper basic strategy perfectly is .40%. When the count is minus (more Aces have been played than fives), exactly even or up to +2, bet the minimum. If the count goes to +3 or +4, bet twice the minimum; at +5 or higher, bet 4 times the minimum. If you have a large enough bankroll (250 units or so) and understand that you will, in time probably lose most of it, this will work for you.
"Oh, great, Mr.Bigtime card counter" I hear you saying, " I can lose on my own thank-you-very-much! Whoa. Chill out for a second. I didn't say you HAD to lose, just that you MIGHT lose. Secondly, what if you were to take maximum advantage of the comps the casino has to offer: shows, rooms, dinners, bimbos. If you're currently betting with $25 chips and losing, this count will trim your losses and still keep the welcome mat out at the casino of your choice. If you'll manage your money carefully, you could go for years and not lose a dime. But how much can you make in freebies?
In this column, things will get more and more complicated, but if you try the Ace-Five count, you'll discover how easy card counting really is. And that's the real bonus here; I may turn you into a card-countin', blackjack-playin' pirate who strikes terror in the hearts of casino magagers worlwide. Hey, it could happen.
As a little 'homework', go visit Grinder's Blackjack Simulation Warehouse. This is a web site put up by a numbers lover and he did some interesting comparisons of the Ace-Five count with other counting methods. You'll see that this isn't a bad count at all and, in fact against a double-deck game, it can be very effective.
