5/10 with a mandatory utg straddle, one limp upfront hero (10k) makes it 75 from MP with QQ folds to Villain (3500) in the SB who 3bets to 300, hero calls.
Flop (650) T83r villain bets 500 hero calls
Turn (1650)9o villain bets 900 hero??
Villain is a LAG semi/pro who has a lot of gamble in him, and was spewing a bit earlier in the session but has since noticeably tightened up. He's generally a smart player though. Hero and villain have tons of history that may/may not be relevant to the hand...but at this point we both respect each other's games and haven't been playing back at each other much recently.
What should hero's plan be the rest of the hand? Is folding the turn an option?
