So?  I saw this kind of nonsense at invited GM events where the best 16 in the
world
were competing.  It just happens...

So?  I saw the #5 player in the world hang a queen to a two-move mate threat a
few years
ago.  He had to either give up the queen or get mated in two moves.  He had
several good
moves to avoid both, but played a move that instantly lost, and it took Crafty
(which was
commenting on the game in real-time on ICC) a one ply search to see this, in a
millisecond
or so.  But the GM made the mistake _anyway_ and he was not in time trouble...

Not _nearly_ as often if the program is well-tested.  But on occasion, even a
computer
will find a lemon move of course...
