this is a full ring hand but I'm posting it here since one extra guy folding ahead of us don't mean jack [censored] about playing out the rest of the hand

I've never seen this guy before but so far his play has seemed more or less TAG and his avatar is a picture of aba.

He's at a couple of my tables to my right and this is maybe the fourth time I have threebet him, although that's over a large enough sample of hands that it's not like I'm just relentlessly pounding on him, and I haven't been getting out of line vs anyone else at these tables either. He has folded to each of my threebets thus far. I think he's reaching the point where he's ready to make a stand against me but with our stack sizes here I'm not too thrilled about getting it all in preflop... so... I "float" him. Yes, no?
