Possibly boring river decision

[aK13]

20/40 live

BB (villain) is a 40 year old middle eastern looking guy. Literally just sat down this hand and doesn't have chips to call preflop yet (he has them for the flop). I would just naturally assume a slightly LAG read on these types of fellows, but thats just experience.

Kinda fishy lady cold calls, old guy in SB who is talking about "respect for the game" blah blah calls, BB calls.
