[I dunno]

But all the money isn't going in on the flop. Not until hero raises.

This hand is a lot harder to play because it wasn't raised preflop.

Edit: I should have gone back and looked at the OP. I thought he was putting in a full buyin on the flop. Even still, the OP said he thought Villain had at least a 6. And although it's just another ten, it's still a losing play in the long run to call the flop just because you're getting 2-1. So what? You're going to be forced to call the turn as well because of pot odds no matter what falls.

It would be different if the pot was raised preflop, and hero thought the button was trying to steal a decent percentage of the time. But that's not what happened. He's not protecting a pot that he is continuation betting and could easily have just a nake low draw. If the OP said, I think he probably has a six, but could have just a naked low 1/3 of the time, then thats fine.
