yes, and this although dann is only using the 4-piece EGTB, which comes as a
download with my program. you can compute the 6-piece EGTB on your own machine,
and i once computed the 8-piece EGTB - unfortunately, that is much too large to
put on the web unless you're at a university like jonathan schaeffer...
with the 8pc EGTB you get much more hits of course.
