Don't you just love these out of position TPTK hands

I think I would put him on TT, 88 or ATs. He was happy to call pf and let 4 people see the flop. (which would be bad with AA or KK). There are some hands that you could be ahead of AQ, AJ, QQ, JJ.

Assuming he is not real Laggy, I think I am folding here. He has already committed nearly 1/2 his stack to the pot. So I think he probably has better than a pair.
