How light does he value shove? That first hand is close, just because your hand could easily be KQ/AK or something and he could be value shoving some worse two pair. I don't mind it though, cause the possibility of QJ should keep him in line somewhat.

Second hand is a good fold.

Third hand I'm really really tempted to call this, given that you folded to his previous river c/r's. Not sure what level he's on here. You're mostly afraid of 67 here I'd imagine? I think a set might bump a raise on the turn at least, cause that card made the board very coordinated. Of all the hands I'd want to call the third the most I think.
