What's my move? UB 10/25

adversity is a regular in these games, and is a winner as far as I can tell.
His stats read 26/14. (VPIP/RPF) I hadn't been at this table for long when this happened, not sure what villain thinks of me. What's my move?

I dont play these stakes but I would fold. Its a ring game whats the rush. Wait for a better spot. In my world TPTK isnt that great of hand. Also as harrington says....'you asked a question and he answered it' wait for a better spot or a stronger read. with no read its an easy fold.

His weak lead smells a bit, then you raise to see where you stand and he answers bu going basically AI. That would be a strong play on his part without a read on you, some crazy aggro might make such a move with just a draw but this smells like a set all the way across the sea. I fold..
