I doubt he ever has a 2pair here given his stats. The only sensible 2pair he can have here is KT and even then I doubt he's calling with that.

Sets are possible although it can be argued that it should have raised OTF, so his range I think is weighted more towards made flushes. Given a range of sets, AcTc,Ac9c,QcJc,QcTc,Qc9c,JcTc,Jc9c,Tc9c (and I'm being tight with this range) and pending further reads I think it's a b/f turn, although in-game I probably call.
