Rating in chess is based on games between not equal players and chessmaster6000
won 5.5:3.5 in the games against p200MMX programs and only lost elo because of
games against weaker opponents.

If you win Rebel8(p90) 9.5:7.5 then you lose elo.

Chessmaster is one of the top programs.

I am not sure that is the best(there are not enough games to say) but you cannot
decide that chessmaster does not deserve number 1 because of the fact that it
played against weaker opponents.

Chessmaster did 78% when Fritz532 did 66%.
They have the same rating because the calculation of the rating considered the
fact that chessmaster played against weaker opponents.
