Thinking here is straightforward - on flop when he calls the most likely hands are some sort of straight draw or a nut flush draw (villain wasn't too bad so is unlikely to be calling with absolutely nothing). On the turn, 9T is unlikely as I can't see many people chasing that straight then checking it with a flush draw on board. River is a total blank and I'm checking to him - if he has, say, a weasly two pair he'd probably check it down as I'm unlikely to call with a weaker hand. There's no straight likely, no flush and there's no reason to believe a K has hit him (A would be different as he possibly has a nut flush draw). More often than not I think most folks would check down AKxx here as they'll win if I was just on a draw but probably won't force out many better hands.
Only need to be right 35% of the time to start turning a profit, so here it looks a fair call. He hasn't told a convincing story and so (even though it's a good bluff that would force me out with a variety of winning hands) with as little as one pair of jacks I can take a look at his hand. HH converter didn't seem to work perfectly - anyhow, he had some low wrappy thing with a low flush draw and my pair of jacks won the pot.
