Everywhere you look when trying to beat the casinos at blackjack, the hi-lo count rears its ugly head. The movie "21" in 2008 accelerated this count to the masses. Almost every book published since 1966 recommends this strategy. The internet is infested with 2-6=+1, 10-A=-1. A can't miss count presumably. It can be argued that hi-lo cannot detect blackjacks and insurance. Since aces and tens are counted together, the probability of predicting blackjacks that correspond with the count is impossible. All aces gone in a single deck game (Reno rules) with a +2 count at 1/4 deck played is a almost a 2% disadvantage with the 2.4% deduction from blackjacks. More aces played than normal can do serious harm to the player. Conversely, an even count with no aces seen at 39 cards left, blackjacks will increase from the 4.83% off the top to 6.47%! The hi-lo player missed out on this positive situation. In insurance instances, hi-lo strikes out due to aces being counted as high cards.

A calculator was used to confirm these numbers, not a computer simulator. After Edward O. Thorp's "Beat The Dealer" in 1962, the casinos panicked. Something had to be done. More decks were added to confuse the Ten Count player. The 1966 revised edition of "Beat The Dealer" introduced Harvey Dubner's High/Low count. Julian Braun of the IBM corporation did the faulty computer work that has fooled the masses since. The mob controlled casinos were happy. Card counters bought the half truths hook, line, and sinker. Casino consultant/blackjack expert Stanford Wong "fixed" the overlay's of 7,8,9's from Braun's "mistakes"(see "Blackjack High-Low Card Count Shattered" on YouTube) in his 1975 book "Professional Blackjack" with yet another computer sim. Wong and other "recognized" blackjack authorities relied on sims for their results and condemn the mathematics when challenged to this day.
