I've often heard to treat OBBO / OBO just like American Blackjack where dealer peeks for Blackjack. I've just found this a little hard to fully wrap my head around.
So let's say a Dealer has a face up Ace.
I have 88, I can't surrender against an Ace.
I split.
Would I play the same basic strategy as dealer peeks?
I'm wondering if under OBBO, there is increased incentive to "not bust" so I might not hit a 15 or 16 vs an A as keeping the new hands alive means I get more "rebate" for if the dealer gets a blackjack and I get to win more on the 12% or so chance the dealer busts with an up A.
Is there a gold standard resource for ENHC OBBO basic strategy somewhere? Surely the at least the EV's of the actions change between OBBO and OBO..
I feel like I have to frankenstein a card together where if the dealer has an A and I want to double against it, I have to change take ENHC EV and add back 4/13.
