1/2 NL 6max Prima
Villain is a TAG and has 198. I cover. He's two to my right and has been folding a lot to my CBs.

The hand before, I'm in the SB with AA. A couple of people came in, I raised big. One caller. Flop rags, I push him around and he folds.

Very next hand I get K[d] K[s]. I raise UTG to 8. All folds and villain who limped UTG now raises me to $20. I call.

Flop ($43) 7[s] 2[h] 6[d]. He leads $32.

Is he just sick of me raising or is this a monster?

I would say since the hands happened back to back, I'm more likely thinkin that hes sick of you bullying him around... That or a 99-JJ type hand... I think Ice has said that he's never seen anyone limp UTG w/ AA at 6max... I raise him pretty hard here, to $100 even and prolly call a push... If he really reraised you PF w/ 66, congrats to him...

I agree with Ice, normally I would call here but since you've been pushing him around a lot already, keep on doing it. You have a huge hand and it's unlikely that he will give you credit for it.

I think it is read dependent, I have not seen limp reraising with less than KK from good players. Donks limp reraise with JJ and AK.
Some players like to slowplay their monsters (so he would check the flop with AA), or make smaller bets when hit (or vice versa), here you need some additional information to make the decision.
With your pushing table around you also need a kind of a read, If you went into his head and he started to make crazy stuff - push, if he is solid good TAG I think fold is better.

P.S. I am not sure that I would fold it in the heat of the battle.

P.P.S. Just noticed that black_knight gave about the same response.
