[200NL] Extracting Value

[vetiver]

No info on villain, first time playing him and I just sat down. Everything standard until the turn. I have no idea what his 3bet calling range is. At this point (the turn) I don't want to represent JJ+ and get him off a weaker hand, get him to throw away his T9 or TT or whatever he might float with. I also think it makes me look weak which will lead him to bluff the river w/ air or value bet a medium strength hand for value, both of which I can checkraise allin (unless river comes 7 or 8) and get max value in both instances. As it plays out, he passes on the river and I don't get him to stack off where it appears I may have if he would've continued on the turn with J9. What do you think of this line? Am I more likely to see a greater return just betting the turn or repping weakness going into the river? P.S. I probably would have just had to call any river bet here given OESD on board.
