nice game. Simply shows that if anyone works hard enough, they can do
well working on a chess program. It helps to know what has been tried
before, so that it is possible to jump into new areas sooner.
however, keep it up. After years of playing "second fiddle" it's nice
to see the amateur programs making a big comeback... :)
