I agree. It just seems to know the best move instantly. It doesn't need to
calculate anything, which rarely changes its first choice. This is a great
strength at faster time controls, but I wonder about slow time controls such as
in correspondence chess where players let their machines run overnight to obtain
the best move for a position. Perhaps Shredder, Fruit, or Fritz are better in
that situation. Also based on various reports we must also switch to a different
engine (not Rybka) as the endgame approaches. So maybe Rybka is an engine to be
used only in the middlegame. I use my own opening book anyway.
