I like your turn fold, once they cbet, you call and the SB over calls, I'm pretty much done with the hand unless we make a set.

I'm calling the flop, it's a paired board and we have position, I'm not folding for one.

Yes I think you can fold the turn quite happily (or unhappily!). He can't be barrelling too many bluffs in this spot so his range kinda steers towards overpairs. Is he doing this with TT/99? Possibly but he's also doing it with QQ+ and you also have to take into account Kosz still has to act - be horrible if you call turn and Kosz jams.

Looks like an okay fold. Hard with the guy in the SB. He can and should have hands that beat us and when he calls the BB should realize that both of your ranges can bink this board hard and slow down.

Folding for one bet here would be really exploitable so unless the villain is a total nit I'd be calling at least once. That being said turn fold seems fine, especially given the stakes and three-way spot. I can't imagine an average tight NL10 villain to do this as a bluff or with worse hand than yours very often.
