Blackjack calculator: From basic strategy to optimal strategy using card counting

<h1 align="center"><font size="5" face="Arial"><strong>Blackjack Calculator</strong></font></h1> <p><font face="Arial">The JavaScript program on this page enables the computation of the optimal strategy during a game of blackjack. The computation is depending on the cards that are used up before. </font></p> <p><font face="Arial">It is a well known fact that the average of the player is changing depending on the mixture of the remaining cards. So card counting can be used to get a favourable strategy against the bank. The mathematical forumlas are based on the actual probabilities of the several card values.</font></p> <p><font face="Arial">To calculate an optimal strategy please begin with an input of the actual game situation: Click on the button "Decks:...&quot to increase the number of used card decks. After this use the green buttons of the 4th row to decrease the remaining cards (the red buttons of the 2nd row can be used for undoing). Also select the rule. </font></p> <p><font face="Arial">The computation is an approximation based on the assumpation that the actual probability distribution of remaining cards is fixed during the following game. All results are shown depending on the first card of the bank and in total. </font> <a href="blackjack.htm">Blackjack calclulator</a> <p> This page is a demonstration of the power of mathematics in blackjack shown first by Edward Thorp 1960 and described in chapter 17 ("Blackjack: A Las Vegas fairy tale") of my book <a href="/index_e.htm" target="_top"><font size="2" face="Arial">Luck, Logic and White Lies: The mathematics of games </font></a><font size="2" face="Arial">  (<a href="http://www.galois-theorie.de/pdf/luck-logic-white-lies.pdf" target="_top">preface, content</a>).</font></p> <p> Literature:<br> Beat the Dealer: A Winning Strategy for the Game of Twenty-One, Edward O.
