On de_nuke with the bomb planted lower and you covering the bomb from inside one of the side doors, is a smoke in front of the door advantageous to the CTs or yourself?
I would never purposely smoke myself out if I was inside of the door. A technique you can use to prevent the smoke being effective for the CT is line up the bomb from different angles and shoot 1 bullet on the wall to mark it. Then, no matter what the situation or which side of the door you are peeking from, you have a very good idea of where the defuser will be standing. Watch some demos of Lim on nuke if you want to see this done perfectly.
