I am convinced a min/raise of a big bet on a very wet board by a $10NL player is someone who thinks they have teh nutz. I really doubt it's a semi-bluff, unless you have some reason to think that this particular guy is even capable of a semi-bluff raise.

I think the worst he has is KJ or QJ... there are many other hands with 2p plus that you are behind as well, not to mention an oddly played KK/AA.

Oh, I just read results. I cannot fault you for playing overpair+oesd (even with tainted outs), but I could imagine folding here against someone who hasn't shown much aggression history.
