I'm not understanding the folks that say fold pre. The preflop raise is standard 3x the big blind. Hero will flop a set 1 time in 8 so if we can say this is the average size raise Hero will have to call each time with his pocket pair and if we look only at set mining then:

7 times Hero will not flop the set so 7 x $0.12 = $0.84 cents lost
Therefor the one time Hero does hit that set all he has to do to break even from this is get 84 cents from Villain which does not seem like it would be hard to do especially if Villain hits top pair or has an overpair.

Now that's just breaking even. How many times will hero stack Villain?
How many times will that small pair of 44 55 or 66 end up hitting a straight
How many times will Hero look at Villains bet on the flop and know Villain missed and that small pair wins at showdown?

It seems to me that as long as the raise needing to be called preflop is reasonable then it would be -EV long term NOT to call. Opinions please.
