re: Poker & Please for your opinion
In your situation.... Villain 3 bets wider than AA likely. Usually way wider than AA. 4 bet ur KK.... Most of the time your goal is to get it in pre with cowboys. Of course there are exceptions to this. However in your scenario, you shouldn't be set mining KK. You should be 4 betting for value. If he 5 bets then you can reconsider based on his stats. If villain only 5 bets with AA (some players are like this) then unhappily fold.
If he flats your 4 bet then you should be pretty happy, because your likely ahead. But I assume your playing micro-ish stakes, so in general.... always try to GII pre with KK. I wouldn't ever wanna be flatting with it. Be the aggressor, and take control
