I have invented a system for casino blackjack which can be used productively against a single-deck with a 6:5 payout on naturals. Using BJStrike, I have simulated play on two billions decks and posted a screen print of the results below. If you wish to obtain this blackjack system, you must purchase a copy of my book, Axiomatic Theory of Economics, and contact me with a copy of your receipt.
Note that, while the publisher asks $117, the book can be had for less at www.amazon.com or a number of other book dealers, and a receipt from them will also satisfy me.
