First of all I would like to take this rare opportunity to say thank you for providing all of us this fantastic platform that brought me many enjoyable hours (and also a little bit of money).
I know that we users are essential as well, as we fill your community with "life" and content, but first of all there must be somebody who had the idea and who initiated everything ... and that was you! :)
Therefore lets keep it simple: Do you know how to play chess?
I wonder why so far you never ever have solved any of my chess challenges!? :-)
