Weird top 2 hand vs "tag"

[djshawk]

Villian is running 23/17 over about 50 hands with aggression on all streets >3. I would call him a tag from his stats but he limped preflop so I'm thinking that may not be the case at all.

I was confident he'd bet the turn if I checked it but didn't expect to be 3 bet back again. At this point I really couldn't pinpoint a hand for him, I think my line looks quite bluffy too.

What is the best thing to do here? I'm leaning towards push to get value from FD, funky overpairs etc. I really can't see him having any hand with a 4 in it, so 99/TT are the only hands that beat me but there is only 1 combo of each so both hugely unlikely.
