Raise or call this river?

[mongidig]

20-40 live 9 handed. I have TAG image and running real well. I have shown down nothing but big hands KK,AA after raising preflop. The game has one very loose player on the button and the rest are all fairly tight and good.

Two players fold and I raise with 7d7s, folded to SB who calls(He is terrible, plays every hand etc.), BB calls(seems to be a decent, tight player but no great reads)

The flop: 7c6hTh

Checked to me, I bet and both call.

The turn: 7c6hThJc

Checked to me, I bet, shockingly the SB folds, and the BB calls.

The river: 7c6hThJcKc

The BB bets, Should I raise or call?
