What is the effect of this dealer error?

Dealing another fundraiser last night and was reminded that not everyone is even close to the knowlege level here at WoV. We were talking about how if someone wanted to run a benefit game for real payouts (ie: esentially a back-door game) it would never work since a smart player would see the rules, including 2:1 BJ and make it a benefit for themself. I'd be the first!

Anyways, another dealer with some dealer-school and I were talking and he stated a third dealer there was paying *any* 21 at 2:1! He was in charge and moved her to roulette (don't ask me that logic.)

So, my question, mathematically what would this error be worth to the player? For review:

4 decks
S17
Split anyh 2 cards
Double on any 2
Unlimited Resplit allowed EXCEPT As
NO SURRENDER

And the dedaler erroneously pays *any* 21 2:1?

the 2:1 pays alone makes it player advantage, correct? do they just count on people not knowing how to play to make money?

[sorry, can't crunch your numbers]

For much worser rules (i.e. ENHC, D9-11, no resplit) I get +4.6% player advantage (pushing 21 with dealer Blackjack).

Edit: Sorry, that was for 3:2 payout.

You would need an entire new set of basic strategy rules, too. Probably hitting a few more hands than you would with normal rules, especially soft hands. probably splitting a few more hands than you normally do, too. Probably surrender far less frequently, if at all. I don't see how you can calculate a new player advantage percentage unless you figured out a new basic strategy already.

Any 21 pays 2:1? Wow! I'd suddenly be hitting 16s where I normally stand. Hell, I might hit 17 as well! Definitely split those tens too!

I'm inclined to believe that there would be a player advantage even if they were paying any 21 at 3:2...

Thing is she was oblivious to what it woulod do, lucky it is only play money. I read a story on one of the dice forums that at one casino, a *real* one, craps dealers were pulled to BJ and one let players split ANY TWO CARDS. IOW, split an 8-7. Not sure how long they said the pit boss took to find that one out, but it shows why gaming boards have training minimums now.
