Calling down w/middle pair

[ssmallz]

Villain here is fairly aggro (40/20) and I haven't seen him do much to get totally outta line.

I open w/JdTd UTG, Villain in CO calls as down BB

Flop K64r

I bet villain calls BB folds

Turn Jc putting 2 clubs on the board.

I bet villain raises, I call. Villain range could be Kx, Jx and semibluffing a flush draw so I'm not totally convinced I'm behind when he raises the turn.

I c/c.

Standard?
