You mean the Topalov game?  Fritz found that one in a few hours, and I did an
overnight run with Crafty 16.5 or so (whatever was out at the time) and that
found it too. :)  I understand what you're saying of course, but who is to say
that no one can program a computer to *plan* in chess.  To look at the
opponent's moves and try to deduce his plan, and then see which plan can be
implemented?  It's tough but it could be done.  It may be harder to do than
regular improvements using the current methods, but I think that's the main
difference in how humans and computers handle chess.  A plan makes it easy to be
highly selective in your move choices and what you analyze, and if this could be
implemented in software even to a moderate degree it would make the programs
much stronger.  If it were done successfully it would be increasingly hard to
say who has a greater "understanding" then.
