Top set - when to stop raising?

[RossSi]

I guess we're putting him on a made straight on the turn, rather than TT, AT or a lower set (99, 77) or some other two pair. It seems like hands we beat make up a larger part of his potential range here. Plus a lot of online - and perhaps live players) will wait for the turn to raise with a flopped set and sometimes two pair.

If he doesn't cold call with J8 or 86 then don't we have to put him on something we beat (and think he's putting us on top pair) and 3B the river.

I think three town the river.
