Since I've been playing on this site, I've been seeing a lot of face-up AA limp/raise moves, which simply don't work online.  However, given that this guy has raised before, I'm a little suspicious of his AA.  Actually, the reality is that I'm putting him on a range of AA,KK,AK - whose range obviously has me dominated.

However, if I can guarantee that he's never folding his AA,KK to an all under flop, is there ever a way of justifying this call?  In other words, if I know I'm going to stack him every time I hit my set, is this call justifiable?

I've generally been folding to the limp / raise, but I'm starting to rethink my strategy with these pocket pairs and suited connectors.

FWIW, this is an auto-fold for AK, etc.

Obviously, I'm 100% ahead here.  I flopped the nuts.  I'm so positive he has AA, KK that I call the flop bet in order to ensure that the turn is not an A or K.

The dry nature of this flop is such that there are virtually no turn cards (barring a very slight chance of a turned Ten / quads) that will push him off of his hand on the turn / river.  If he checks the turn to me, I can bet around $15-20 and push the safe river.

If I am 100% sure of his hand, and he's drawing to "4" outs (2 in reality), why not reduce my variance and take half of his odds away from him?  I am 100% confident that I can fold to a turned Ace or King (more than likely Ace, a King would be a lot harder fold for me).
