I am pretty much definitely raising this preflop. I want to play heads up (yes, with JTo) against the 70/14 dude who basically limped in the cutoff.

SB is passive, so it is likely he checks the turn. I can imagine him checking any non top pair hand unless he's improved, but I think he will bet any top pair hand on the turn. You beat most of the top pair hands he could have, and I think him checking the turn is too likely, so I like raising the flop.

Turn is a must bet. It would suck if he check raised you there, and it would be a fold, imo.

River is also a bet if he checks to you, but it is pretty close. He probably would have raised a T on the flop or an A on the turn, so you're basically betting and hoping he has called you down with a 2 or a low pocket pair (which is decently likely).

If he check raises, I don't see how it can be a bluff, so I'd fold. As you said, he hasn't been tricky postflop thus far.
