and to add what I would do if someone called me:

1) if the button calls me it's the last bet I put in the pot, almost regardless of turn/river.

2) If someone to my right calls me and I don't improve on the turn I check and re-evaluate on river. On a J or 9 river I might call some kind of bet but not much, and might valuebet smallish if it got checked to me again.

3) If someone to my right calls me and a J or 9 lands on the turn I bet somthing in between $45 and $70, as a kind of blocker: small pairs might still call me after which I will check behind on river. I will fold to a c/r on either street or a check call on the turn followed by a riverlead.
