what I like about it is the extra pot equity. The difference between 2 chances and 3 chances to make a hand a is significant especially the difference between calling or raising.
i dont rely on implied odds to much in limit games because it is only a bet or two. But especially in multy way pots you could take a card off on the cheap round for aweaker hand like an inside straight draw.
Maybe you are only getting 6:1 immediately, but you have the chance at 6 or more big bets on the later rounds if you hit on 5th, giving you odds of 18:1 or better. with those kinds of odds you could probably take one of with some of the weaker 3 flush hands too?
Stud high isnt my game.
