After being alerted to the fact I may have endorsed a book that may be leading unsuspecting blackjack players into wagering their hard-earned money on false and misleading information, it has caused me to pause and reevaluate my position on the worthiness of McDowell\u2019s information.<br><br>After first reviewing McDowell\u2019s pre-publishing draft of his book regarding attacking casino blackjack through various manners of locating aces and using that information to a player\u2019s advantage, I was quite impressed with his reference to ace location techniques, various card and shuffle tracking theories, and his application of these theories in an attempt to develop a different method of attacking the game.<\/p>\n\n\n\n<p>This information was also supported by numerous citations to works done by a host of gaming and mathematical experts ranging from Dr. Ed Thorp to &#8220;The Bishop,&#8221; Arnold Snyder. My first examination of David McDowell\u2019s draft lead me to write that it was &#8220;\u2026an interesting example of how the game of blackjack can still be exploited\u2026and\u2026a must read for any player interested in assaulting the casinos\u2026&#8221; At this point I felt it was unnecessary for me to check McDowell\u2019s math since his basic arguments sounded rational and, for that matter, I\u2019m not an expert in mathematics.<br><br>Over the last several weeks I have been contacted by several gaming experts that have questioned my endorsement of McDowell\u2019s book. The reason for this concern is based on errors found in mathematical equations that McDowell uses to support his theories on attacking the game of blackjack; specifically his reasoning that claims to provide the knowledgeable player an approximate 4% advantage over the casino.<\/p>\n\n\n\n<p>If these calculations are wrong and the advantage that a skilled player may obtain is less then 4% (or resulting in a negative situation), then I have personal concerns that a number of players may be unaware of the diminished situation that financially awaits them. To add to this concern the text in question happens to have my personal endorsement printed on its back cover.<br><br>Being an author myself, I more then understand that mistakes will happen. My first book,\u00a0<a href=\"http:\/\/www.amazon.com\/gp\/product\/B00072B2PS\/ref=as_li_tf_tl?ie=UTF8&amp;camp=1789&amp;creative=9325&amp;creativeASIN=B00072B2PS&amp;linkCode=as2&amp;tag=writeaholic-20\" rel=\"noreferrer noopener\" target=\"_blank\"><em>Pai Gow Without Tears<\/em><\/a>, had over thirty grammatical errors that were discovered after the first printing. I know that mistakes will sometime be made and I also know they can be corrected.<\/p>\n\n\n\n<p>Before condemning David McDowell\u2019s work as being worthless, I feel he should be given a chance to re-work his equations and review the theories he has established. Although I don\u2019t know David personally, I can\u2019t imagine he would ignore the chance to make corrections to his material and provide the gambling public a truer version of his work regardless of whether the corrections support a method of beating casino blackjack or prove the contrary.<br><br>If for some reason the errors are not re-worked and corrected, then the author\u2019s intentions can be considered suspicious. If the correctness of this material is not the most important aspect of McDowell\u2019s work, then at this point his work will be open to condemnation by the various gambling and mathematic experts as being on the same level with Olsen\u2019s TARGET strategy and Ponzi\u2019s pyramid investment scheme.<\/p>\n\n\n\n<p>Before I completely pull my endorsement of David McDowell\u2019s\u00a0<em>Blackjack Ace Prediction<\/em>, I would like to give him a chance to correct any errors or incorrect theories. To err is human; and I doubt McDowell\u2019s intention was to deceive. Well David? What will it be?<br><br><em>[Note from Arnold Snyder: McDowell has never publicly responded to the criticisms of his book. His publisher did provide an errata sheet for the book, which corrected some of the errors, but not all, and was unfortunately shown to contain more errors.] <\/em>\u2660<\/p>\n<a class=\"synved-social-button synved-social-button-follow synved-social-size-48 synved-social-resolution-single synved-social-provider-facebook nolightbox\" data-provider=\"facebook\" target=\"_blank\" rel=\"nofollow\" title=\"Follow us on Facebook\" href=\"https:\/\/www.facebook.com\/lasvegasadvisor\" style=\"font-size: 0px; width:48px;height:48px;margin:0;margin-bottom:5px;margin-right:5px;\"><img alt=\"Facebook\" title=\"Follow us on Facebook\" class=\"synved-share-image synved-social-image synved-social-image-follow\" width=\"48\" height=\"48\" style=\"display: inline; width:48px;height:48px; margin: 0; padding: 0; border: none; box-shadow: none;\" src=\"https:\/\/www.lasvegasadvisor.com\/gambling-with-an-edge\/wp-content\/plugins\/social-media-feather\/synved-social\/image\/social\/regular\/96x96\/facebook.png\" \/><\/a><a class=\"synved-social-button synved-social-button-follow synved-social-size-48 synved-social-resolution-single synved-social-provider-twitter nolightbox\" data-provider=\"twitter\" target=\"_blank\" rel=\"nofollow\" title=\"Follow us on Twitter\" href=\"https:\/\/twitter.com\/LVA_Tweet\" style=\"font-size: 0px; width:48px;height:48px;margin:0;margin-bottom:5px;margin-right:5px;\"><img alt=\"twitter\" title=\"Follow us on Twitter\" class=\"synved-share-image synved-social-image synved-social-image-follow\" width=\"48\" height=\"48\" style=\"display: inline; width:48px;height:48px; margin: 0; padding: 0; border: none; box-shadow: none;\" src=\"https:\/\/www.lasvegasadvisor.com\/gambling-with-an-edge\/wp-content\/plugins\/social-media-feather\/synved-social\/image\/social\/regular\/96x96\/twitter.png\" \/><\/a><a class=\"synved-social-button synved-social-button-follow synved-social-size-48 synved-social-resolution-single synved-social-provider-youtube nolightbox\" data-provider=\"youtube\" target=\"_blank\" rel=\"nofollow\" title=\"Find us on YouTube\" href=\"https:\/\/www.youtube.com\/c\/LasVegasAdvisorSHOW\" style=\"font-size: 0px; width:48px;height:48px;margin:0;margin-bottom:5px;margin-right:5px;\"><img alt=\"youtube\" title=\"Find us on YouTube\" class=\"synved-share-image synved-social-image synved-social-image-follow\" width=\"48\" height=\"48\" style=\"display: inline; width:48px;height:48px; margin: 0; padding: 0; border: none; box-shadow: none;\" src=\"https:\/\/www.lasvegasadvisor.com\/gambling-with-an-edge\/wp-content\/plugins\/social-media-feather\/synved-social\/image\/social\/regular\/96x96\/youtube.png\" \/><\/a><a class=\"synved-social-button synved-social-button-follow synved-social-size-48 synved-social-resolution-single synved-social-provider-instagram nolightbox\" data-provider=\"instagram\" target=\"_blank\" rel=\"nofollow\" title=\"Check out our instagram feed\" href=\"https:\/\/www.instagram.com\/lasvegasadvisor\" style=\"font-size: 0px; width:48px;height:48px;margin:0;margin-bottom:5px;\"><img alt=\"instagram\" title=\"Check out our instagram feed\" class=\"synved-share-image synved-social-image synved-social-image-follow\" width=\"48\" height=\"48\" style=\"display: inline; width:48px;height:48px; margin: 0; padding: 0; border: none; box-shadow: none;\" src=\"https:\/\/www.lasvegasadvisor.com\/gambling-with-an-edge\/wp-content\/plugins\/social-media-feather\/synved-social\/image\/social\/regular\/96x96\/instagram.png\" \/><\/a>","protected":false},"excerpt":{"rendered":"<p>Regarding David McDowell&#8217;s\u00a0Blackjack Ace Prediction by Bill Zender (From&nbsp;Blackjack Forum&nbsp;XXIV #2, Spring 2005)\u00a9 2005 Blackjack Forum It appears that my endorsement of David McDowell\u2019s recent publication,&nbsp;Blackjack Ace Prediction, has dragged me into a controversial issue dealing with the author\u2019s responsibility to provide true and correct information to the gaming public.
