Hi,

Are there any sources available online that discuss the mathematics of

calculating every possible chess board position and linking the positions

with every possible move. Obviously the number is far beyond what
computers

are capable today, but I am interested in some exact numbers to predict
how

much longer we will have to wait to see a computer play a 'perfect' game
of

chess.

After much time and work, I believe I have calculated the exact number of

possible board positions. Has anyone else calculated such a number?
I'd be impressed if you did! Sure you could calculate the number of possible

piece positions with basic arithmetic but that wouldn't be the whole answer.

You would have to throw out positions where the king is in check, and other

impossible positions. You'd also need to account for the 50 move rule, and 3

move repetition - boards with identical arangement of pieces are not

neccesary identical positions (eg has the rook or king moved).

But you did say after much time and work, so perhaps you have done it! Whats

the answer? Please show your working

Regards,
