I'd probably 3-bet the flop to collect an extra small bet from SB when he's behind, but I don't hate the smooth call of Button's raise because he's representing a big Q and this looks like a prime opportunity to get an extra BB out of both opponents on the turn. I don't think there much chance of the turn checking through, so going for the checkraise seems like a reasonable line to take.

But if you're going to sacrifice a bet on one street in order to pick one up later, then do it.
