is there any other Software out there, that advises to hit with hard 12 against the 4 in a 1 deck (still well-balanced) game, as my Software (Black Jack Advocate) does?
The reason for that it is better to hit is prosaically, that by hitting a small card you not only betters your hand but also increase the probability of the dealer to bust; if you hit a ten-counting card you would decrease the Probability of the dealer to bust, but as you already lost in that case, this has no influence to your expected value. Only the decreasing of the dealers probability to bust after you hit a small card makes a difference. And in a 1 deck game this difference is enough to make hitting to the better move. (You find the mathematically prove for that at http://www.bj-advocate.com/Calculation/Calc_Example.htm )
I would be interested if there is any other software with the same result. If not, I guess my software is the only one that calculates correct.
