Advanced single-deck blackjack
Casinos that offer Blackjack games in one pack are aware that they can be easily defeated by a counter that uses a large difference of betting and then try to play with a gap between 1 and 12 as I have pointed out for games with 6-packs and you’ll probably be a one way ticket to immediately leave the casino. This does not mean that you will be “identified” if you bet more than 5 chips in one hand, but I think it’s fair to say that making money with a good game with a single deck requires a larger bag of tricks than there is need for a game with 6 decks, then started the most logical thing, and that altered the game of your hand according to the count.
If you know how to count cards, you can use the count to know how much to bet on each hand, but you can also use it to help you play more accurately than any single hand. If you have studied my course up to this point, you know one of the key factors if you want to win at Blackjack is to leave the table when the True Count drops to -1 or lower, but this tactic is not very practical one deck, because only a few hands are dealt before shuffling.
Accordingly, you should play more with “negative” decks, but the good news is that a shuffle is never far away. At the same time, we know that the casino’s advantage increases as the count decreases, so we need to neutralize these negative effects as possible. As you play the game with a single deck, with many negative counts, what you need is to learn the game for hands like hitting 12 against the dealer’s 5 and so on. Low counts we must avoid double down or split pairs, and in their place we will have to pull. However we will not have to guess, but we need to learn the Basic Strategy variations for scores “low” as -2, -3 and so on. A realistic range for the True Count with a single deck is between -6 and +6 which covers 85% of all the hands you play, assuming a penetration of 63% which is very good.
Some players prefer to learn only the indices for some hands more likely, with the idea that they will get a hand like A, 4 on a 5 less than 100 times in every 100,000 hands of play, but more often have a 16 against 10. In this book, “Blackjack Attack” in the second edition, Don Schlesinger devoted a chapter to what he calls “The Illustrious 18? which are, in his opinion, the most important changes of the Basic Strategy. I’m not good at reproducing the original work of other authors, so I will refer to the book for a complete list if you think you can not store all the changes I’ve listed so far. Another idea worth considering is to not learn the indices below -2, with the rationale that, with these scores, you probably will bet the minimum allowed, so every game you error committed in the long run, will cost shortly. Or, would you want to learn only the indices to be making such bets extra, as in double and Divisions, with the idea that putting more money on the table must play the hand correctly.
