Basically I'm just trying to find out how bad I'm affecting myself by doubling down at times where the basic strat says not too.
2 2,A -28.51% 4.56% -6.35% 0.0008809
4 6,2 -19.98% 4.38% -5.40% 0.0009192
4 5,3 -19.67% 4.46% -5.12% 0.0009192
2 3,A -28.50% 2.21% -6.39% 0.0009192
3 2,A -24.47% 7.38% 0.20% 0.0009192
2 4,A -28.49% -0.09% -6.76% 0.0009192
5 6,2 -15.50% 7.93% 2.23% 0.0009192
5 5,3 -15.38% 8.08% 2.59% 0.0008809
3 3,A -24.46% 5.04% -0.06% 0.0008809
2 5,A -28.24% -2.14% -7.00% 0.0009192
4 2,A -20.18% 10.43% 7.06% 0.0009192
3 4,A -24.20% 2.91% -0.22% 0.0009192
6 6,2 -11.87% 10.68% 8.22% 0.0008809
6 5,3 -11.44% 11.15% 9.20% 0.0009192
3 5,A -24.16% 0.83% -0.61% 0.0009192
4 3,A -19.92% 8.28% 6.97% 0.0009192
2 6,A -15.27% -0.03% -0.49% 0.0009192
Those were taken from the wizard of odds site. Basically this adds in Doubleing down on the following situations
8 vs dealer 4,5,6
Soft 12-17 vs dealer 2,3,4,5,6
2 2,A -28.51% 4.56% -6.35% 0.0008809 for example
Difference between hitting and doubling is -10.91%. Take that divided by the probability I get 0.00961%.
Doing the same for all of those I get a total difference in the house advantage of 0.08%.
Am I doing this right or do I have a decimal place wrong or am I just using the numbers wrong? I was expecting a loss, but not that small. If I extend the idea to include doubleing basically on every hand I would never bust and the dealer has a 2,3,4,5,6. The total differance would be 0.57%. While this even gets into situations where I wouldn't even double on a whim, I was surprised to see the house advantage was still relatively low(still considerably lower than games like 3card poker).
