I have not played there but find it curious that it says you can play and learn FREE on SimpleChess until February 1, 2014. After that, some parts of the server will remain free, while others will be available at nominal fees. Apparently things haven't been updated recently and when I visited and logged on 'Play' there were, according to the server, 270+ games being played. Also, over 800,000 members?!
