Hand is just that I pot 3bet (K5)(K4) over a 3x BTN open and got pot 4bet 133 BBs deep and I wasn't sure whether I should go with it, just flat and play it OOP or even fold.

Stats of villain were 70/33, AggF 73 and a (pot)cbet of 4/4 over 33 hands and we've played a couple of noteworthy hands before (chronological order, quick succession):

I opened (A8)(Q7) in the CO and got flatted by him and another player, he c/r on A96 rb and pot jammed on a rainbow 3, I folded.

He opened BvB with (QT)T6, I called (AK83), he pot cbet, then we checked it down on J856Q rb

He opened BvB, I called (A6)Q6 - pot cbet, call A87 rb - chk, chk turn - he potted river I repotted with the rivered nutflush, he folded

Then I got the KK hand and wasn't sure if this is enough history to just gii pre even though I haven't seen him reacing to 3bets so far and thus don't know anything about his 4b range.
