kk 200bb deep vs lag on drawy board

[my1ifesavins]

villian is 25/20/2.3 over 150 hands. I have 3bet him several times before but never light I have been getting hit with the deck. I stacked villian with kk vs ak ai pre like 30 hands before this. Besides that it seems like villian could be tilting and he seems to be flating alot of 3bets pre.
