Question by jay c: What,s the correct way to insulate a basement stud wall?
Here is how I planned to insulate my basement walls. First, I would drylock them. Next, I would use dow blue or pink board and glue it directly onto the concrete. This is where I get confused. Should I press the stud wall directly up against the dow board so once I put up the unfaced insulation no air can get it. Or should I leave one inch between the dow board and stud wall to allow the wall to breathe.

You do not need drylock unless you have a moisture problem. If you do look at your exterior grade or gutters as those are the most common source of moisture in basements. Personally I like to frame a conventional 2×4 wall and use R-13 Batts insulation. If you don’t want to sacrifice the additional space then what is typically done is to glue and either tapcon or ramset studs to the exterior walls and then fill the spaces between the studs with foam insulation whish is glued to the wall. Cover with Drywall. The additional reason for the 2×4 wall is that it gives you room to run electric, cable, telephone, ethernet and plumbing.
