yes interesting thought and I agree with you: the playing differences will in
most cases diminish at longe time controls but the superior engine will always
win, perhaps only at closer margins. Nevertheless it is not always true, that
the difference will diminish, see for example this experiment:

Shredder 7(CB) vs Fritz 8.0.0.5



Game              Total    (+  1/2 -)

  5min/game       63.0-97.0  (40-46-74)

 10min/game       68.0-92.0  (49-38-73)

 30min/game       72.5-87.5  (47-51-62)

120min/game       68.5-91.5  (43-51-66)

you see no difference at 5min/game and 120 min/game contrary to the
ChessTiger-Rebel-Match.
