working through chess games - where to sit/board position

Any reason you can't get up and look at the position from the other side of the table? I do it from white's perspective but check things from black's view now and then. Oh, I find it very useful to have a second smaller set for sidelines and such. I use a little 12" magnetic folder that's been doweled/ duct taped permanently open from Amazon for maybe $20. It's plastic but gets more use than my fancy ebony or bud rosewood sets...LOL.
