If his strategy doesn't involve any turn semibluffs, then we have a fairly reasonable idea of his range.  I'm tempted to call here getting 2.5-1, given we have a minimum of 10 outs but more reasonably 16 outs.  Additionally, we can lead Q and perhaps 9 rivers as a bluff, as well as leading all of the rivers that give us top set or better.  So, we can jam 17/44(38%) rivers as well as get to showdown reasonably easy on board pairing rivers that counterfeit his 2pr's(T,3 seem like the bet ones) (6/44)

^ good post

and since turn didn't bring a flush draw, that makes it more likely villain already has a made hand so raising seems bad.  folding is bad just because we have so many outs as stated above. therefore call.
