There are some controversies in the definition of the rules. Some sites say that you cannot Double UP with 21 or with BJ. However, the Wizard of Odds apparently allows it
after splitting a pair of aces. I don't know which rule is correct.

Still haven’t looked up the rules but did check Wizard site
-Push 22 -6.91% Push16 excepting player 21 is likely more. Player still goes first and is subject to busting prior to dealer resolution
-BJ 1-1 - another -2.7%

Those 2 rules alone -9.61% and likely more
