I don't think the turn check is as bad as everyone else makes it out to be. It's perfectly fine as long as you're doing it to trap, rather than for pot control. There's no reason to fear being behind on this board.

What I don't like is your turn check combined with your river play. The small raise just reeks of a marginal hand looking for value that can't stand heat. Would you ever bluff this small? Probably not. Would you raise this small with a set? Probably not, because you're checking the turn in order to get paid more than you would by betting. QJ? I don't think I've ever played against you, and I don't know your style, but most good players won't make such a small raise with a monster.

Raise it up to 650-700, then you can feel free to fold to a push.
