A chess program in squeak! That's very interesting. I was just playing with the idea of writing a go program in squeak, so definitely I could use some ideas of yours. (Particulary 'on the higher level': gui, game control and so on). Maybe I should look at the chinese checkers demo too. (By the way, does anyone happen to have the rules of that game ? )
Squeak seems better suited for go than for chess programming, because the emphasis is more on clever programming than on mere brute force. (And as we all know it is easier to be clever in squeak than it is in c!)
Just some thoughts of a squeak newbie (my first message on this list!)
