Thanks Gordon!
As to the house edge, I'm at 0.77% based on infinite decks. I tend to subtract 0.1% for a six-deck game, but if you have a true six-deck figure, I'm all ears.

I have calculated house edge to be 0.766%, in good agreement with your value. My calculation is a hybrid - its a cross between 6 decks and infinite deck.
So many better men, a few of them friends, are dead. And a thousand thousand slimy things live on, and so do I.

Perhaps it was a coincidence we were so close. I found a small error and have adjusted my number to 0.6185%. Here is more of a breakdown.
| Event | Probability | ER | EV |
|---|---|---|---|
| Dealer small hole card | 0.307692 | 0.062772 | 0.019315 |
| Dealer medium hole card | 0.307692 | 0.075949 | 0.023369 |
| Dealer high hole card | 0.337278 | -0.011184 | -0.003772 |
| Dealer BJ | 0.047337 | -0.952663 | -0.045096 |
| Total | 1.000000 | -0.006185 |

For what it's worth, I interpreted a rules card from a table last night as saying that 10-10 made AFTER a split is pushed by a dealer 22. The 21 wins, though.
'Emergencies' have always been the pretext on which the safeguards of individual liberty have been eroded.

That is my understanding too.

I am unclear on 11 v. 5 in Blue Mode. Double, or Hit? Thanks.

I get: Double 11 v. 5 in Blue Mode (2-5 hole card), which is in agreement with the Wizard's strategy.
(For Double 11 v. 5 in Blue Mode, I get an infinite-deck EV of 0.194. And for Hit, I get 0.159.)

Thank you very much, ChesterDog.

This is now an old thread. I am grateful for all the work people put into it.
Just to be clear, did we ever figure out what the true house edge is after all the changes this thread went through?
thanks
