30000 starting.  Down to 22000.  Have played few hands, lost one big pot with JJ to villain, other than that have played few hands, and showed down only one other.  Villain has been the most active at the table, seems to be TAG given the showdowns I have seen, but for how active he has been, he at least at times could be playing LAG.  Villain has 48000. I believe he perceives me to be tight, possibly tight passive given lack of hands played.  Blind levels are 100/200/25.  Playing 7 handed.  Hero is on the button, Villain BB.  Folds to button with Hero having 7d5d.  Hero raises to 500.  SB folds, Villain raises to 1100.  Hero calls.

Flop is Kc5c5s.

Villain leads out 2300.  Hero raises to 4800.  Villain reraises to 12000.

Hero?

My thoughts on his range given this line would be AA, KK, AK, possibly some A high flush draws, and Ah5h.  I think KQ very unlikely.

Thoughts to this point would be appreciated.
