Hello, I don't really want to post another naive "How many possible Chess positions are there?" comment, but I believe that of the huge number of possible positions only a relatively small fraction are actually interesting. What I mean is, if you could count all possible piece/square permutations I suppose most of them will be materially unbalanced, with the outcome generally in favour of the side with greater material. These positions could be considered "solved". Then a small fraction of these will be materially balanced or almost-balanced positions, with an unclear outcome, and could be considered "unsolved". Does anyone know whether any estimate has been made on the proportion of unsolved to solved positions in Chess? I guess it would represent a substantial trimming of the overall game tree. Cheers, Mike.
