TPGK against fairly unknown

[DGDolly]

Villain hasn't been here long, maybe 30 hands, I don't have exact stats, but he has been limping every 3 hands it seemed. We only played one other hand where he raised me from SB and I called and raised his c-bet on the flop, he folded (flopped top pair + nut FD, not that it matters).

We have roughly 100BB each.

Standard fold right?
