Villian is 18/11/6 over 250 hands. How is my line? In general I havent been 4 betting here with much of anything unless Im deeper then 1buyin or the villian really sucks.

I might reraise him to $18 preflop, if he pushes he is fearing nothing and is likely holding AA.

As played it seems fine, he is checking it down with what is probably JJ or TT, maybe AK.
