This is tangentially related to crypto. I've been reading A.K. Dewdney's _The New Turning Omnibus_ recently to refresh my memory of all that stuff I learned in undergrad that I'm going to see again on the Comp Sci GRE shortly. :-) Anyway, I was glancing through the chapters on complexity, computabilty, and minimax trees, and I got to wondering something: how many possible games of chess are there? I know that it has to be a finite number, but I'm not sure how to go about finding this number. Any pointers would be appreciated.
