On this wintry December rating list of 2019, we can present three new entrants.
First out is the Komodo-version which won the ICGA World Computer Chess
Championship (WCCC) and World Software Chess Championship (WSCC) in Macau this
summer. Komodo is programmed by Mark Lefler and Larry Kaufman, and we have used
Erdogan Guenes opening book for the testing. After 520 games it has placed
itself third in the rating list with a rating of 3470 on our 1800X platform.
This is 5 points ahead of the 13.02 version and 16 points behind Stockfish 9.
Next out is a newcomer on our rating list, namely Vajolet2 2.8 by Marco Belli.
So far we have only played 123 games, but after those first couple of matches,
it has performed admirably with a rating of 3301. More games will be needed
to get a more reliable rating figure and lower the error bars, but the start
has been very good. We have used Sedat Canbaz free opening book "Perfect2019.abk"
for the testing of Vajolet2 2.8.
Last out this time is the manually tested dedicated chess computer from the
Millenium GmbH company, named Millenium ChessGenius Exclusive. It has an
ARM Cortex M7 processor which is clocked at 300 MHz, and has the famous
ChessGenius program by Richard Lang. Similar to the testing of
ChessGenius Pro, we have used the opening book by Mark Uniacke for the
testing. After the first 101 games it has achieved a rating of 2251, which
is 85 points higher than the ChessGenius Pro.
Some notable losses/gains from the previous list was: Komodo 11.01 Q6600 and
Booot 6.3.1 Q6600 which gained 10 points each. The rating of Komodo 13.02 1800X
and Komodo 13.02 MCTS 1800X fell after more games was played, and they lost 17
and 23 points. Arasan 21.2 Q6600 also lost 15 points from the last list.
Our upcoming plan is to get more games with Vajolet2 2.8 on the 1800X level and
also to be able to present enough games with it on our Q6600 hardware.
The Q6600-version missed the mark for this list, but will be introduced in the
upcoming rating list instead. We will hopefully also be able to introduce
some other new programs for that list.
For all those that celebrate Christmas and/or New Year, I will take the
opportunity to wish you all a Merry Christmas and a Happy New Year from us in
the SSDF.
Lars Sandin
P.S. Minor correction from the last list: It was Fauzi Dabat's opening book
which we have used for the testing of Stockfish 10, and not Sedat's. D.S.
