200NL HU cash FTP vs absolute maniac

[r1base14]

Villain was running about 55/45/14 through 150 or so hands and loves to fire with air if i appear weak, even two barreling often, or raising smallish turn bets. I had pretty much had it with him, and had the utmost confidence that my K was good. Comments on all streets welcome. I will post results after some comments. See below:
