This is really bad. You are not representing any hands that will make him fold a better made hand that he was planning on stacking off with on the flop. He has a ton of nut hands in his range. You're essentially betting double pot that he has a draw when many of his draws aren't strong enough to raise/shove on the flop vs your flop lead on this board. What you do have going for you is that you block T9 and don't have any spades in your hand.
