Computers even before 1999 were at GM strength.

Genius already in 1994 beated Kasparov 1.5-.5 at 25 minutes per game and
kasparov at 25 minutes per game is at the same level as the average GM at
tournament time control.

I do not say that Genius3 on p90 when it use only 25 minutes per game is at the
same level as GM's at tournament time control because one result may be
misleading but in 1999 the hardware was clearly better than the p90 so we have
no proof that Fritz or shredder or Junior could not do the same against humans.

I know that Rebel did also slightly better results against humans in the israeli
league but I think that the reason is simply the fact that more humans have
Fritz so the opponents who play against Fritz were more often prepared to the
games than the opponents who played against Rebel.

I know that one of the masters who played against both Rebel and fritz did not
prepare for Rebel but prepared for Fritz so he lost against Rebel and drew
against Fritz.

These matches are considered as uninteresting after the win of Deeper blue
against kasparov.

Until 1997 there was a sponsor for a tournament of humans against machines
in holland.

These tournaments were stopped after the win of deeper blue against kasparov.
