I would raise the turn. I think he is almost always blockbetting a smaller pair. I'd much rather raise the turn than the river... I think you'll get called much lighter on the turn.
Unless I have a note that he will gaybet to induce I would always raise turn.
I'd raise to 3x and bet small on the river.
I'd raise to 17 and shove rivers when I have air at least some of the time.
