How big of a cbet or real bet

[Mibbeh]

Let's say you have KT on the button, some limpers, you raise 5BB, 1 caller.

Let's say the pot is 13BB

1) Flop KT2 rainbow
2) Flop KT2 suited
3) Flop Q52 rainbow

What I mostly want to know, is what should go through your mind? Do you want to suck him in with a smaller bet if you hit or you want to bet big and hope he has something worth playing. What should the difference between a real bet and a c-bet be? etc.

I've found myself making bigger c-bets(3/4) then real bets. My c-bets get folded most of the time, but if I hit a real hand, it gets too ... If they both get sometimes more called and sometimes more folded, it comes more up to cards or what? So I've been making bit smaller bets on flop(1/2) and bigger bets on turns, because then they seem to be more pot commited and take my bigger bet as a bluff, after the small flop one. Though, I've got suspicions, that this isn't the right way to go /images/graemlins/laugh.gif Bluffed pots should stay smaller and real pots bigger? Can somebody clarify me these things?

Thanks in advance.
