I think they're more likely to call QQ/JJ to a river bet after turn checks through. Facing a turn bet with river yet to come, in a 3bet pot vs the aggressor, I would be really surrprised to see a seemingly disciplined player call QQ/JJ. He's gonna hate the bet and he's going to expect a river shove. He might call if it's a half pot bet for showdown though.

I really don't expect to get two more streets from QQ/JJ after this turn, that's extremely optimistic imo. And I think we're much more likely to get value from those at river than turn.
