Is there any connection between chess and pi?

I'm sure there's one out there somewhere, but mathematicans and chess enthusiasts have just yet to discover it!

As much as I want to believe there is one, I don't.. Except that the pieces usually have circular "feet"... 

But I suppose it depends how you define your connection, cuz you would properly be able to find some farfetched border-line conspiration theroy-like connection...

1. Use it in the manufacturing of the chess pieces, for the parts that have a circumference.
2. Give out a pi as a reward to winnder of a game of chess.
3. Whereas Pi is an irrational number, Chess has number of irrational players.
4. I am reminded of the 'knights of the round table'.
5. If as curved space-time suggests, Euclid's 5th theorum (or was that postulate?) was not necessarily correct, and so all apparently straigt lines are actually curved, and so you could picture a square board as part of a curved surface on a sperically shaped object that requires the use of pi to describe.
6. The both appear in the previous posts: so the words 'pi' and 'chess' are actually both present in the same posts and threads.
7. I am full of it, and 'it' is has a circumference describable and calculatable by the use of pi as well based on the anatomical structure it is formed in.
