I think you want at least one more player in there to go for the overcall. There's no reason to think that the sb is bluffing so he'll call your raise.

I'd have bet/called the turn, but I wonder if bet/folding isn't correct depending on the action after you bet. For example, if you bet and MP calls but SB raises, I think you should fold.

Also, again, I'd have bet the turn, but I see why you checked it. I'm in a questioning stage right now. I'm questioning everything I take for granted since I'm in a downswing. I'd like to see what others say
