Do you think the button has overcards here the majority of the time? If not I can't see why you'd want to check-raise if he's a half decent hand reader. He should put you on a medium PP here almost always. You raised preflop but didn't cap. You bet-called the flop. Kind of screams medium pair imo, so the only reason to check-raise there is if he can fold overcards or TT/99, both which I doubt will happen enough times to make it profitable. Of course, if you truly believe he has overcards here (I don't know how you could know this by the action so far?) your check-raise has a lot of value.

What am I missing?
