When backbetting in a splitting situation, we must decide whether the split is 'offensive' or 'defensive'. An offensive split might, for example, involve splitting 3's against a 5, where each hand has a positive expectation against the dealer's card. In this case, it is correct for the backbettor to split also. With the defensive 8's versus 10 split, we should be careful this time not to blindly 'follow the leader'.
