I also do not like the $1 license but I think that the only person that can
complain if there is a problem is Hyatt and not you.

Your impression is not relevant.
The limit between borrowing some pieces of Crafty and modifying Crafty is not
clear.

I believe that the main reason that Hyatt gave permission is the fact that it is
not a chess playing program.

It is clear that you need to change the move generator and a lot of things when
you have 8*10 board.
