I decided not to because I was worried about a slowplayed fullhouse, and thet he wanted to give a free card for someone to make their flush. Thoughts?

its more likely you are beaten by the nuts flush than a slowplayed boat.

so you Raised and Flop&River bettor 3-bet... I think a call is fine... you have to be good here 50% otherwise.

But... raise the flop, by the way.

Raise this flop like it's your job.
Turn and river are good.
