I think 3rd is a fold because 3,7,a, and 4 are already out there, so two pairs and regular straights are unlikely. i understand the authors state you can play those hands, but do you really want to play it with one diamond already exposed. To me that is like playing 3 diamond hand with 3 diamonds exposed on 3rd street.

It is possible that in a very big 5 way pot drawing to a straight flush is possible, but I wonder if this isnt better applied to hands like 889 that 554?
