I start with $850. Limped pot 5 ways to the flop, Hero checked BB with 10d 8h. Pot $25

Flop QxJs4x - Checks around.

Turn 9s - Hero checks, UTG limper bets $20, 2 callers and folds back to me. Hero?

I check raise to $100. UTG makes it $300 and has about $125 behind. Others fold. Hero?

He's a reg, I don't have any history but have seen enough to know he's not getting out of line very often (if at all). Pretty much an ABC tight player. My image is probably aggressive. I had 3-bet two times already at this table and followed up with big bets.

Thanks for the feedback.
