I don't know if anyone has ever used it, but I'll bet you my entire bankroll (except one penny of course :) that someone somewhere sometime has used it. I think the following could be the Gordon Count's first time "in print" for free. First I'll give risk averse strategy adjustments using a modified version of the "bj-strat" program. Then I'll give the multiparameter adjustments for all the side counts.

Multiparameter Strategy Adjustments =================================== You can improve your strategy by using side counts. That's what is meant by "multiparameter strategy adjustments". Of course, side counts will give you headaches for multiple decks, but then you don't get much for strategy adjustments on multiple decks anyway, so then you might switch to High-Low or Zen or Halves, or perhaps just keep a side count of aces. Strategy adjustments are worth *beaucoup* on deeply dealt single deckers. In fact, very deep in the deck, strategy adjustments are worth much more than ranging your bet according to the count. You can find a deeply dealt single decker by choosing the right casino and/or by choosing the right number of players (e.g., 2 rounds of 7 sitting towards third base.) Below, the only columns that really make sense to use are A, 6, 7, 8, 9, i.e., the cards which Gordon counts as 0. For example, look at the very first line of the table, the "0" in the top left corner. If you have 17 versus dealer ace then excess observed aces should be counted +0 (i.e., as if they were a neutral card.) That was easy, eh? But look at the "1" under the 7-column. This means that excess observed sevens should be counted as +1 (i.e., as if they were a small card for the purpose of this decision.) If you have seen 3 sevens in half a deck, then you saw one excess seven over the average. After adjusting your count, you then use the regular Gordon strategy adjustment tables. So excess observed sevens will make you less likely to hit 17 vs. ace (probably because it's that much less likely that the dealer has a pat 18 to try to beat.) The columns are for the card being side counted. Some of the numbers, particularly for splitting, seem a bit wacky and probably are erroneous. This table was generated using hand typed data from _Theory of Blackjack_ (and a simple program to process these data) and so human error is possible in some of the values. Use at your own risk. You can and should reformat the data by hand into the format used in _World's Greatest Blackjack Book_. You have thus far paid me insufficient funds (my records indicate a total of $0.00 to date) to do this grunt work for you or to do the extra work necessary to figure out where the wacky values are coming from. See _World's Greatest Blackjack Book_ and _Theory of Blackjack_ for more information on multiparameter counts. For example of how to reformat, you would have an ace adjustment table that looked like this: DEALER UPCARD HAND 2 3 4 5 6 7 8 9 10 A 17 +1 +1 +1 +1 +1 +2 +3 +2 +1 0 16 +1 +1 +1 0 +1 +1 +1 +1 0 0 etc And then a separate table like that for each of the other cards you wish to side count. With this count, it would be a good idea to side count 6's 7's and 8's in one group, for maximum bang for brain cells. You can do this by averaging their adjustment values. [There is no more plain text after this point, just tables of numbers, so you may wish to skip the rest of this article. Remember, the columns below are the side count cards.] DEALER A HITTING 17-12 A 2 3 4 5 6 7 8 9 10 0 1 1 2 0 0 1 0 0 -1 0 0 1 1 2 1 0 0 -1 -1 0 0 1 1 2 3 0 0 -1 -1 0 0 0 1 1 3 3 -1 -1 -2 0 0 0 0 1 3 3
