First REAL hand

After four more agonizing folds I decide to jump in when I pick up 4dAhKdJd giving me three broadway cards with a king high flush draw. I'm in late position and limp in. Flop comes JcTcJs. Cool, trips with top kicker. I bet .10 into a .12 pot. All folds and one flat call. Uh oh. I would rather have just taken it down right there. Very draw heavy flop so Villain could have anything from a boat to two pair. Turn is 3s. He checks and I bet .16 this time and he calls. River is a 2h. He checks and I check behind. He shows JhAd3cKh which is the identical hand except that he has a trey to my four. After he boats up on the turn I went from a 51% favorite to a 13% dog. Jacks full of threes. Should have known. Now down .33.
