1. For an opportunity to try out new (and sometimes bizzare) openings without fear of destroying your rating.
2. Because I play at work during my office hours sometimes and if a student walks in I have to resign the game. Playing rated games makes that sting a bit.
3. I enjoy playing for the beauty and enjoyment of the game and nothing more. That is ideal chess to me. If rating points are tied to the outcome of the game I tend to play a bit more stodgy.
can someone please tell me why they create unrated games on live chess? I just don't understand it. Whenever I want to play a live game I prefer to click on the rated ones; I often see a preponderance of unrated ones. Can you people who create unrated games tell me why you do it? No judgment, just puzzled interest.
