Not raising with KK on good flop

[jt1]

Let me explain to you why you need to raise: You loose more equity for every flop peeler that comes along than you gain from their extra small bets.

Lets say your chances of winning this hand if you raise and knock out both players behind is 75% and if you just call and let both players in that falls to 60%. I'm sure the Math will say that you should raise despite the two extra sb's you gain.
