Uh, wat? That makes no sense. Fold equity and pot equity are totally seperate.
I want to make three points.
1) You can play sc's two ways, semibluffing or trying to cheaply make your draw. You dont always have to semibluff postflop (and often if villain calls a 3-bet, you shouldn't). Thats what makes SC's so hard to play. They can be played either of these ways, and often newbies pick the wrong one.
2) Postflop equity (and how the hand plays) adds to your EV just like more fold equity from the ace blocker does. You're just neglecting it because its harder to quantify. But having a hand that plays miles better than A4o in a three bet pot helps.
3) Or to put all this in math form...
EV = (Pot*Fold%) - (3betSize*4Bet%) + (PostflopEV*Call%)
You are focusing on the first two terms of the equation (how often our opponent folds or 4-bets) and you're neglecting the postflop term. And for stakes up to at least 1/2, that postflop term is significant, since most opponents will still be calling a decent chunk of three bets.
Blocker hands would be all we three bet if our opponents never called. But that world doesn't exist. Being able to flop profitable equity in the event we get called is pretty important when 3-bet bluffing.
I'd also like to talk about this on Skype.
