Bet more on the turn. You're not making it a mistake for the flush draw to call you here.

I make it $15-ish on the river. SB isn't overly in love with his hand.

Bet at least $9 on the turn. SBs hand reads as a draw but the only draw is KT/9T maybe with a club. Maybe he has a weak Q and if you're overbetting like that on a second J on a 3 club board he knows he's toast so it's not a great spot for an overbet.
