The problem with slowplaying AA and KK is that you are not going to improve on the flop very often and you then only have ONE PAIR.

I hate the fact that you are slow playing from MP1 too. OK, slow play from time to time if you have the button and the CO raises..... but in this hand anyone to act after you is getting good odds to call and the blinds are getting great odds to call with any old trash (say, T4)....

You might feel you are trapping, but quite often YOU will be the one trapped, not having any idea where you are, playing a large pot OOP with 1 pair.

Here's a word of advice:

Never slowplay anything

I would say that at least 90% of the time it is done, it's wrong. Until you learn when to slowplay you're much better off just not doing it.
