I believe it's double up with 2 cards only, including after split, but not with blackjack.

I was modifying Blackjack PowerSim to simulate the new rules. I wasn't able to get my code to work for the double up bet and decided to quit working on it. If anyone is able to program this rule into PowerSim, please let me know.
