Quiz answer:
this guy is clearly a TAG, but with only 94 hands, I don't think we can read too much into his 16% 3Bet stat. This is also BB v SB, so he could definitely be flatting some hands here which he might 3bet a lot otherwise. I think his range at this point is something like any pair below TT, any broadway, and a handful of suited connectors. Maybe also some suited Aces.
When he check-raises the flop, his value range is pretty damn small. JJ, 55 and 66 are the only really strong hands I can see. I would have expected JJ+ to 3Bet PF almost all the time, so I would heavily discount JJ and overpairs. Some people go crazy in spots like this with top pair, so I could see some thin value hands like AJ and KJ sometimes doing this. It is also very likely that he sees us as a TAG, and knows we probably missed this dry board, so he has just decided he is going to take this pot away from us!
With the small bet on the turn, I really don't think he has better than TPTK. We have already called a check-raise, so if he wanted to play for stacks he could be about $40-$45 here and setup a nice, easy river shove. I think his range now is something like this:
Value hands: 55,66,TT,JT,AJ,KJ
Semi-bluffs: KQ,78s,98s
Bluffs: a whole lot of air that tried to steal it on the flop and doesn't quite know what to do now!
