Here is what happened in this position, where
two grandmaster-strength programs took over.
I gave the lost position to the stronger one, and
the winning position (White) to Fritz 5.32. Much
to my surprise, Fritz was unable to win the game,
although in many cases its choice of moves was
a perfect match. All it took was an occasional
"suboptimal" move, here and there, to let the win
slip away... .

...and here I stopped the game, being too
tired to continue. Clearly drawable, it could
take weeks before Fritz might make some
further errors, or it could repeat for a draw
at any time.
I gave both programs plenty of time to
consider their moves, so it was a bit of a
surprise that Fritz 5.32 could not reel it in.
A graph of the game shows a flat line with
a huge advantage from moves twelve all the
way to move twenty, then things started to
do downhill for Fritz.
