2/4 - rivered nut flush on paired board 160bb deep

[zook]

Villain is an aggro regular, running 21/19/4.3. I stacked him 150bb deep earlier this session on a big cooler (my turned str8 over his turned 2 pair in a 3 bet pot). That was awhile ago though so I doubt he's steaming.

gotta call because you cant get value from worse often and you cant fold because his range is sooo narrow

Folding and raising suck so I guess that leaves you with one option.
