Subject: Collectors corner: the Dieren 1987 tournament (part 2)

Hi fellow collectors,

A few days ago I reported about the human-computer tournament in the Dutch city
of Dieren, 1987. It was organised by Dutch computer chess protagonist Jan
Louwman. I already showed you my first win against Mephisto Dallas 68.020.
Searching in old computer chess magazines I also found game number 2 against the
same machine.

No tactical games this time, but a quiet opening in which the computer had no
bad position, but then run out of ideas. It started to play waiting moves and to
my big surprise the Dallas didn't see the little trick 23.d5! coming. So I was
able to beat the World Champ two times! Here is the game:

[Event "Dieren 1987"]
[Date "2006.02.10"]
[Round "6"]
[White "Noomen, Jeroen"]
[Black "Mephisto Dallas 68020"]
[Result "1-0"]
[ECO "B15"]
[PlyCount "53"]
