Re: 10% refund question
[ QUOTE ]
My quick math tells me this is a marginally winning. Assume a 1% house edge in BJ playing perfect strategy. X is your EV.
.49X - .51X + (.1)(.51X) = .031X or a 3% advantage.
Anyone read this any differently?

Aside from the fact that you gave the house a 2% advantage, I believe your method is ok IF you are going to play a single bet...and either double your money or get a 10% rebate on your loss...
In reality, the house advantage accounts for the 1.5 payoff of a blackajack and the times you double/split. So the real calculation is more complex, but the idea is generally the same...
