When is it a set?

[amoeba]

the lead is interesting to play against.

I think I used to minraise the lead with a TP or overpair type hand and of course fold to 3 bet but lately I find that an inferior line since most people with the set will call your minraise and weak lead the turn or try to check raise the turn.

I think these days I just smooth call the flop lead and check behind if he checks the turn. if he weak leads the turn again, I smoothcall again and plan on folding to 1/2 pot + bet at river if he leads river again.
