This flop is soooo coordinated, you have to raise this flop. He's not going to be able to fold KK,KQ,QJ,QT,JT, QQQ,JJJ,TTT,9T, tons of fd's are combo draws. You really have to raise the flop. This is no board to be slow playing.

As played, all-in. You can't really call, because remaining stacks on river if you call, he'll be so short he can't credibly bluff.
