Raise turn ... Its a big pot and it would be +EV if you folded some opponents. One bet on turn makes it an easy decision for the others to call.

There are a couple of hands that could play this way:
-KK (I think it would cap PF).. but I could see KK going for overcalls on flop
-QJs (May generate PFR and would go for overcalls on flop
-QJo (I don't think it raises PF)
-TT/99/88? is a real possibility.

What does river raise gain you?
If you are trying to force the others out now then its too late - you'll only force better hands to call you and force out the overcalls who are behind.

If you raise for value then you would need to be somewhat confident that you have a good hand. In this case probably not a good hand but not foldable.

I'm calling river vs raise
