However they won't do any harm as long as they are flagged as losing.
Only if such a "stupid" move has actually won a game will there be a slight
chance Rebel plays it.
However, if you have  a senseless queen sacrifice that happened to win one game,
it will get about 0.2 to 0.45 bonus which is usually not enough to compensate
for the -6 material loss, so Rebel will not play it anyway.

I noticed differences to Fritz, too. But I have no idea which program is correct
(MChess' classification is a little different sometimes, too).
Programs often run into trouble with transpositions of openings. I recently saw
Fritz classify an opening as "Bxx (XYZ Variation, 4. or 5.Bg5)" when Bg5 was the
10th move...
