I joined a club here in Madrid and got soundly battered every evening. It was getting to the point where nobody wanted to play me because it was a waste of their time. Despite the rather unsmiling attitude of some, many of the members were perfectly civil and encouraging. I decided, after a particularly humiliating defeat, that I would stay away, study chess, play on RHP and FICS and not return until my rating had reached 1600 on either.
It may take me some time but if I'm to hold my own against players with thirty or forty years experience, I need to tool up. My rating is currently 1370 so I guess I've got a way to go.
Consider it a personal challenge.
So, in my opinion, 1600 is the golden number.
