That is the very reason that I make the source public. And yes, 80 bit words won't be a serious problem.. Remember that the _original_ 64 bit program, chess 4.0, ran on a 60 bit computer, so it had to use two words to get 64 anyway. You will just use 3 on 32 bit machines, or 2 on 64 bit machines. > >I know you have a "non-commercial use" clause in your crafty code, but it is my >hope that 80 square chess with an Archbishop (knight + bishop) and Chancellor >(knight + rook) would make such a creation as I am proposing outside of the >domain of your intended restrictions.
