He's pushing back at my over-pair

[MicroBob]

villain is quite the maniac from my other thread:
68/44/2.5


Hero has QQ in BB

3/6, 5-handed
Button limps, SB raises, Hero re-raises, Button calls, SB calls

Flop:
732 (2 diamonds)

SB checks, hero bets, button calls, SB raises, hero re-raises, button folds, SB calls

Turn: 8 (2 spades now):
SB checks, Hero bets, SB raises, Hero 3-bets, SB caps, Hero calls


River: Js
SB bets, hero calls



against a player like this I would think 3-betting the turn is justified. But after back-to-back C/R's I might be reaching.
