Just finished a 504 game tourney using Fritz 9 GUI and Fritz 9 book. Time was
10 min +3 sec per move. Tourney engines were Fritz 9, Shredder 9.1 UCI, Fruit
2.2.1, Rybka Beta 10d. Rybka 10d was used because when I started this
tournament 2 weeks ago that was the latest version of Rybka. Results are quite
amazing ... especially if you factor in the fact that when analyzing some of the
games, I noticed a lot of games that Rybka missed wins in the endgame would be
won when using Beta 13. So I would imagine if the tourney was done again with
Rybka 13 the results would be even more lopsided. Also Rybka 10d is a huge
improvement over the other Rybka's and it wins a lot of positions that were
drawn in my first Tourney. Still there are some gaps in the endgame, but they
are getting less and less. Mostly glaring would be that Rybka still doesn't
understand how to evaluate positions with opposite bishops, and can misplay many
such positions. Although they might not add to many ELO points, I would say
that in this tourney there were about 20 games for Rybka where it could have
done better had it understood opposite bishops. I am analyzing the games now
and will post highlights.
One other note ... Fruit 2.2.1 is really strong and Fritz 9 is by far the most
mature endgame player. Regardless of the results, Fritz seems to understand
much better than the other engines when a position is drawn. Here are the
tabulated results. I hope the copy paste from Fritz table works !!!
