Stud 8 newbie marginal 6th street decision

[Brocktoon]

I'm a newb too but I'd call that 6th in a second. I'd probably never make it ther though cause I'd fold 3rd.

You're closing the action on 6th and probably have good implied odds on the river if you make the A-high flush. Also, since seat 4 seems to have no interest in betting his hand, and this is .25/.50, he could easily have something like KQ in the hole.
