25NL FR: TPGK. Easy fold?

[Pudor]

I promise this will be my last hand I post today /images/graemlins/smile.gif. No reads on villain. The table was pretty weak-tight, and I thought I perhaps could pick up the blinds with my raise PF.
Should I fold after his min-raise( which stinks of aces or kings)? What about on the flop? I called to re-evaluate on the turn.

Maybe with KJ sooted but I'd never consider raising this with unsuited. Blind steal cost you 1/4 of your stack.
