Computer program tournament

"GF1" stronger than "Gipfted"
During the 6th Computer Program Olympiad in Maastricht (NL), Kurt
Vandenbranden's GF1 played 8 games against Diederik Wentink's Gipfted.
The competition was spread over 2 days - 4 games per day, 30 minutes
per computer/game. GF1 appeared to be the strongest and won with
6 wins against 2.
A convincing victory for GF1, but Kurt says that the score does
not give a right picture of the competition. If Gipfted succeeded
in winning 2 games, it could have won more games. All the games
were very tight; most were played in about 50 moves.
The visitors of this site are familiar with GF1, because many use
it as a sparring partner. Most of the regular Gipfers succeed in
beating level 3, a significantly smaller number can beat level 4,
and only the very best succeed in beating level 5 once in while.
Now, here's something to think about: most of GF1's moves were made
on level 5 and level 6, but quite regularly it dug as deep as level
7, and it even made it a few times to level 8! With only 30 minutes
playing time! Since GF1 lost 2 games against Gipfted, this means
that not only GF1 but Gipfted, too, is most likely stronger than
the best GIPF-players. This asks for a tournament in which computer
programs are allowed to play.
After having looked at the logs, a few preliminary, nonetheless
interesting conclusions can be made. Now that may be assumed that
the programs have played on a level that humans cannot reach - at
least not yet - the logs may tell something about what the future
will bring. And a question to be asked is: Is White the better color?
5 out of the 8 games were won by White. This confirms the tendency
that could also be noticed during the GIPF World Championship in
London, where 22 out of 41 games were won with White. GF1 lost once
with White and once with Black, though, so probably it is still
too soon to say something sensible about it. More significant is
that neither GF1 nor Gipfted lost a game after having taken an lead
of 2 pieces. GF1 lost his 2 games after having been ahead 1 piece,
and Gipfted did so just once. But it must also be said that both
programs played 7 games with only 3 GIPF-pieces (Gipfted played
once with 4 and GF1 - strange! - played one game with only 2!).
3 GIPF-pieces is a "neutral" number; it indicates careful
play. The unpredictable things happen when playing with more than
3 and those who play against GF1 on level 5 know that the odds to
beat GF1 increase significantly when playing with a lot of GIPF-pieces.
So, Gipfers, there's still hope
