I'd guess his preflop range to be something like this: 22-JJ, AJs, AQ, 56s+, Axs, KQs, QJs ?

Flop call could be JTs, A9/5s, AQ, KQ, QJs, float w/ pp or sc (T9, 98, 56...), ?

Turn call is strange. Floating seems unlikely, a slowplayed set must raise, AQ/9/5 would prolly raise, JT still in there, as are T9d/98d/QJd..

River, not much left except AQ/9/5, busted straight draw, or some weird diamond hand like QJ, T9, etc.

I think you should c/c, given that the 2pr hands should bet for you, JT might (rarely) bluff, and a lame flush might value bet less than pot.

I can't really see c/f. If stacks were bigger, maybe b/f, but even that seems weak to me.
