Ask the Wizard #24
Start the same way as I explained with even money bets. Each bet should be the sum of the left and right numbers. However, following your two column strategy you should add double the amount to the right if you lose.

Casino Player reversed the two charts in their layout. I'm very embarrassed by this mistake. Yes, you should hit a hard 17 against an ace if you can't surrender.

I wrote a program in C++ to test all combin(52,7)=133,784,560 ways to arrange 7 cards out of 52. For each one I formed all combin(7,5)=21 ways to arrange 5 out of 7. Then I scored each one of these hands. The highest score of the 21 ways was the value of the seven-card hand. So, overall, I had to score over 2.8 billion hands, this took the computer all night, if I remember correctly.

There is a strict regulation in Nevada that each card must have the same probability of being dealt. Most other legitimate jurisdictions also follow this rule. However, not every jurisdiction is entirely legitimate. Casinos can legally change the odds by changing the pay table.

You didn't state the surrender rule, so I'll assume it isn't allowed. According to my blackjack house edge calculator, and before considering the double any number of cards rule, the house edge is 0.64%. According to my list of rule variations, being allowed to double on any number of cards (a rule commonly found in Panama) is worth 0.23%. So, the house edge over the overall game is 0.64% - 0.23% = 0.41%.
