100NL: Kings versus fish in CO deepish (160)

[Check_The_Nuts]

This dude had started playing back, or at the very least was playing very very loose versus me. He called down on a ten high board with worse than AT (flush draw on board) earlier, and I mean 3 streets. Since then he's check raised me once as a minraise on a A25r board or something really silly when it was 3-way. I've been stealing a ton from button and he calls too often preflop. I'm fairly certain he check raised me small one more time OOP versus button/CO.

I'm running 28/25/9 over 50 hands at this table. Villian is 45/7/1.
