Bodog 100NL. Hero is in BB with Limped around and Hero checks. Pot = $4

Flop----------SB checks, Hero bets $3, MP calls, SB raises to $15.25. Hero calls, MP folds. Pot=$37.50

Turn---------SB bets $46.50, Hero folds.

Insufferably nitty? Effective stacks were 140BB. Dunno, I guess I just didn't feel like stacking off with low two pair at the end of a profitable session. Do you push the turn bet here or what? No good reads on villain, incidentally.
