ANTI Grandmaster play (example)
(see http://www.rebel.nl/rebel10a.htm#ANTI-GM )

I took the example position on Eds page to test the 'anti GM' qualitities of
some other programs (P233MMX, NT 4.0, 128 MB RAM). Especially Junior's
performance is frightening (Rxe6 at 4.5 ply after 2", after 4" even with
positive evaluation!).

No question that Anti-GM-Rebel is now among the very best programs in this
position, so Ed clearly is on the right track ...
