I have a question about the Dr. Pepper Rule. In Blackjack Bluebook II it says to hit when you have 10-2 v. the dealer's 4. In an article ,"Basic Strategy Blackjack has its Exceptions", it says the rule applies only to S-17 games. Which is correct? Both the book and article were written by Mr. Renzey, so I'm hoping that he'll be able to reply. Thank you.
