Exactally when do you not split aces and eights? I am guessing if not DAS split once no peek them maybe you wont split eights against T, maybe. But I doupt it.
Splitting 88's isnt even close to being a yes/no.
I programmed an EV calculator today at work actually

Spitting those 8's is whopping 5%! Only 20 hands of 88 before you are throwing away a whole unit if you dont split.
