  1. Hand Length by Dealer Upcard

    The questions seem to become more and more odd as strange bonuses and side counts abound. These charts show the percentage of hands that are 2, 3, 4, 5, 6, or 7 cards in length, but for each possible dealer upcard. Split hands are counted separately. The sims are for HiLo with full indexes, as that’s more interesting. Six decks, 78% penetration, S17, DAS, one billion rounds each. Obviously, with an upcard of five or six, the player is far more likely to stand pat with two cards. Of course, doubles

  2. Getting old?

    Saw an article today that huge sunspot activity at the end of next year may cause massive technology blackouts. Sounds bad.

  3. Blackjack hands won, lost, and tied by true count and number of indexes

    Modern Blackjack contains a chart of the overall percentages of hands won, lost, and tied and how these percentages are affected by card counting. But, an interesting question came up that I have not seen before. How are these percentages affected by the number of indexes? So, I ran three simulations with full indexes, just the Illustrious 18 indexes, and no indexes. As the effect is slight with shoes, double-deck was simulated. The Hi-Opt II strategy was selected as it has a high playing efficiency

  4. The Casino as Partner

    I was thinking about nasty people and the causes of nastiness. Unfortunately, there seems to be a larger percentage of nasty people in the card counting world than in the set of all humans. Not terribly surprising as the actual practice of card counting can be a lonely endeavor, surrounded by unpleasant and less than interesting people and surroundings. BUT, most of the truly successful counters that I have known appear to be really nice guys (or at least successfully present themselves as such).

  5. Dealer Upcard Manipulation II

    This is a follow on to the Dealer Upcard Manipulation post which should be read first.

    This is the opposite of the previous study. Here, if the dealer knows the next card is a ten, she will always make it the downcard and if it is not, will always make it the upcard. Each bar represents a different card.


    I’ll leave conclusions to the reader.
