I was wondering what you thought of my 3-bet ranges I have been using lately? It is a cut-n-paste job, but seems pretty solid, and has worked well as of yet. I'm guessing I am missing a few opportunities that may be appropriate for current foundation portion of our little "build-a-profitable -poker-player" experiment. I add position bluffs here and there from button and the rare squeeze play, when I see the open raiser has a habit of opening. So there is a high probability that he is weak, plus caller showed weakness also by only calling, giving me a prime time for an squeeze play attempt. I also will 3-bet weak from SB and BB if CO and BU are getting pushy. But what you will see below are my staple 3-betting against ranges, based on what position the open raise comes from.

Defending ranges against the position the raise came from:

UTG:{KK+, AKs}

MP:{QQ+, AQ+}

CO:{JJ+, AQ+}

BU:{TT+, AQ+}

SB:{99+, AQ+}

What are your thoughts of my PFR defense?
