Okay, so the PFR in this scenario is early 30's, he just sat down full 100bb, and i looked over and saw him looking at a poker income app. There arent really any "good regs" in my game typically, but i feel like he might be a 2-5 reg that is playing 1-3 as the game broke early this night and only 1-3 was available.

Anyways

New guy opens to $12 UTG
Fishy lady who is a bit tighter calls UTG+1 66bb(shes flatting JJ and below, offsuit broadways, suited connectors, Suited Ax)
Bttn calls w 33bb and is a pregnant lady who I assume is on the passive side
SB calls w $450 and seems like a TAGfish
Hero is on BB with 98hh covering table.

basically, i know i'm getting a really good price on a call closing the action, but i also dont like that the SPR is going to be pretty low, my flush draws will be dominated, my pairs not very good, not really attractive bluffing opportunities postflop, and a TJQ straight is very dominated. With a shorter stack player on the bttn as well, it becomes even harder to realize my equity. Am I a complete nit for choosing to fold here? I would fold 56s, but not really sure about 76, 87, 98 type of hands. I would defend Axs certainly however. Open to discussion, so please comment :)
