This is the second list of 2022 and in this list we can present six new entries.

The first one out is our new leader in the rating list, Leela Chess Zero 0.28.2.
After the first 280 games played, it has recieved an impressive rating of 3591,
which is currently 19 points stronger than the older Lc0-version. It leads the
rating list with 15 points ahead of Stockfish 13. 
As with the formerly tested version, we have used an Nvidia RTX 3060 Ti graphic 
card for the testing. We have used the 30 blocks + 384 filter network, named:
611213 (date 2022-01-06), and as opening book we have used the free opening 
book "Perfect2021.abk" by Sedat Canbaz.

Our second newcomer are Wasp 5.5 from John Stanback. After the first 194 games, 
it has recieved a rating of 3395. This is at the moment 17 points ahead of the 
formerly tested 5.0 version and at the same time 106 points ahead of the
Wasp 4.5 version. Wasp uses its own included opening book.

We are also glad to be able to introduce a new Chiron 5.01 version on our 
rating list. We introduced Chiron 3.01 by Ubaldo Andrea Farina back in the
August list of 2016. Since that was before the AMD 1800X was introduced
as hardware on our rating list, Chiron 3.01 was only tested on our Intel Q6600
hardware at the time. We have now tested Chiron 5.01 on both our hardware levels.
On our 1800X hardware, Chiron 5.01 has reached a rating of 3356 after 320 games
played. And on our Q6600 hardware, Chiron 5.01 has reached a rating of 3330 after 
280 games played. This is at the moment 154 points over the former 3.01 version, 
so a very nice improvement! As opening book we have used the "Perfect2021.abk" 
opening book by Sedat Canbaz.

Our fourth new program on this list are the latest Marvin 5.2.0 version of 
Martin Danielsson. After 320 played games it has reached a rating of 3330, and 
this is currently 9 points ahead of the formerly tested 5.1.0 version. As with 
the 5.1.0 version, it is using its own opening book in the testing.  

And last, but not least, we are also able to introduce a golden oldie from 1989!
It is Richard Lang's Mephisto Roma II 68000-module, which was released in 1989, 
two years after the initial Mephisto Roma was introduced on the market. 
The special thing with this version was that it was the only 16 bit 
Motorola 68000 based engine which could be used in the Mephisto Mobil-board, 
a small handheld version of their modular series of chess boards. 
Perhaps because of this, they had to lower the clock frequency on the 68000 
processor. It has a frequency of 10 MHz instead of the 12 MHz which was used 
on the 1987-version of the Roma program. As nothing else was changed between 
the two programs, the Roma II should in theory be somewhat lower rated than 
the older Roma program with its higher clock frequency. But, after the 
first 100 games, the Roma II has yet managed to position itself 27 points 
higher than the 1987 version and gained a rating of 1903! 
As the old Roma 68000 12 MHz have a staggering amount of 1519 manually played
games under its belt, one can safely assume that the rating of Roma II will 
become lower as more games are played, and the error bars on the Roma II are 
also still high compared to the more trustworthy rating of its older sibling.

In this last rating list of the year 2022, we can present five new entries. 
First one out is the latest version from team Stockfish, namely Stockfish 15. 
This version landed just a hairline from the number one spot this time and 
grabbed the third position, but only one single point behind the leader Lc0! 
After 480 played games it has earned a rating of 3574, which is 17 points ahead 
of Stockfish 14 and exactly on par with Stockfish 13 at the moment. As opening
book for Stockfish 14, we have used Fauzi Dabat's "Aggressive 5.4 by Fauzi.abk".

Next one out is Dragon Komodo 3 by Mark Lefler and Larry Kaufman. We have tested
both the "normal" version and the Monte Carlo Tree Search-version. The non-MCTS
version of Dragon Komodo 3 earned a fifth place in this rating list, with a
rating of 3571 after 285 games played. It has positioned itself five points 
ahead of the 2.51 version and just four points behind the number one spot at 
the moment!

In the testing of the Monte Carlo Tree Search (MCTS) Dragon Komodo, we have 
used the 3.1 version. It has recieved a rating of 3519 after 306 games
played. It is 41 points stronger than the Dragon Komodo 2 MCTS and took the 
eleventh spot on this rating list. As opening book for both the ordinary and 
the MCTS-version, we have used Erdogan Günes opening book "out10-35.bin".
The sharp-sighted has probably noticed that the nomenclature "x64" is omitted
from the name this time. We can insure that the testing has been done with the
strongest settings, AVX2 and also 64-bit, and that the omission is made just 
because of the length limitations in the naming of the engines. 

I can also add that since most engines that we have tested on both the Q6600 
and 1800X hardware has been 64-bit programs, we will soon make an overhaul to
upcoming rating lists and strip this rather unnecessary designation from the 
names - only adding 32 bit to the names of the few engines that hasn't been 
64-bit compatible.

Well, to get back on track. The next program that we can present in our latest 
rating list, is Alex Morozov's - Booot 7. This time he has used his own 
implementation of Neural Net technology (NN) in evaluation, using Python, 
Delphi and SIMD. This has proved to been useful to the already strong Booot-
program and he has managed to get a rating of 3471 after the first 185 played 
games. This is 42 points ahead of the "ordinary evaluation"-version of 
Booot 6.5 and it now holds the first spot of the engines outside the 
three in the top: Lc0, Stockfish and Dragon Komodo. 
As opening book for Booot 7, we have used the "Perfect2021.abk" opening book 
by Sedat Canbaz. 

Last one out in this rating list is Martin Danielsson with his Marvin-program.
We have tested the 6.0.0-version this time, and it has recieved a rating 
of 3365 after 220 played games. It is 37 points stronger than the last Marvin 
version (5.2.0) which we have tested and we have used Marvin's own opening book 
for the testing.

Since the last rating list, Wasp 4.5 1800X gained 14 points, Pedone 3.1 1800X
gained 10 and Arasan 23.01 1800X gained 9 points. Biggest loss since the last
list was Lc0 0.28.2 which dropped 16 points in the lead. Other notable losses
was Roma II which lost 13 points and Chiron 5.01 1800X, which lost 8 points.  

The next rating list will probably be released relatively soon and will feature
the manually tested Revelation II A.E. Komodo 12.1, and hopefully also contain
some more engines on both the 1800X and Q6600 hardware level. We will also 
begin testing of a more recent version of Lc0 soon, so hopefully it will have 
enough games to be presented as an early bird in the next rating list.

Since the last rating list we can now present six new entrants in the list. 

First one out is our new leader in the list: Lc0 0.29.0, and also the first 
program that has broken the 3600-barrier in our rating list. More games will 
be needed to lower the error bars, but after the first 297 games it has placed
itself 39 points over the last version tested with a huge rating of 3610! 
It will be interesting to see how it will hold up as more games are played 
against the top programs. 
The Lc0-version which we have tested this time is: Lc0 0.29.0, with the 
19 filter + 512 block network, named 808544 (date: 2023-01-12). As with the
earlier Lc0-versions, we have used the free opening book "perfect2021.abk" 
by Sedat Canbaz for the testing of Lc0.

Our next newcomer in the list are one really strong comeback from the team of
Ed Schroeder and Chris Wittington. Chris Wittington is formely known for 
programs such as: Chess Player 2150/2175, Complete Chess System 
and Chess System Tal (I and II). 
Ed Schroeder is of course known for many of the old dedicated chess computers 
like for instance: Mephisto Polgar, MM IV/V, RISC (I and II), Rebell
and also for versions of his program in the ChessMachine ISA-plugin card for PC.
On the PC-scene he has made the Gideon and Rebel-program famous and lately also 
made several interesting and strong versions of his ProDeo-program.

Since last year they have utilized Neural Net-technology in their joint
effort and has seemingly improved fast. We have waited some time to test it, 
since we wanted it to share most of the functions - like for instance Pondering 
and Multi-Processor functionality, which the others programs that we test on our
latest hardware uses. The version which we have tested is named: Rebel 16.2 and
we have used its own opening book, made by the famous Jeroen Noomen, for the 
testing. After the first 209 games, this strong combo of the program: Rebel 16.2,
and the opening book of Jeroen Noomen, has managed to get an impressive rating 
of 3544 on our 1800X hardware. It is placed 10th in the list at the moment, 
just 5 points shy of the Stockfish 12-program. 
A very strong comeback by Ed, Chris and Jeroen!

Our next addition to the list are Jon Dart's strong and reliable Arasan-program. 
The version that we have tested on our 1800X and Q6600 hardware are Arasan 23.4.
On our 1800X hardware it has reached a rating of 3524 after the initial 160 
games played. That is at the moment 75 points ahead of the formerly tested 23.01
version and a very nice improvement indeed! More games will of course be needed 
to lower the error bars a bit. 
On our Q6600 hardware, Arasan 23.4 has reached a rating of 3439 after 361 games 
played. We never tested the 23.01 version on the Q6600 hardware, but Arasan 23.4 
are a whopping 202 points ahead of the 21.2 version at least! 
We have, as always, used Arasan's own opening book for the testing.                   

We are also glad to be able to present a new strong Wasp version by John Stanback, 
namely Wasp 6.5, on our latest rating list. After the first 242 games played, it 
has reached a rating of 3433! This is 55 points stronger than the 5.5 version 
which we tested before, so a nice improvement there also! We have used Wasp's own
opening book for the testing. 

And we can now finally show the first rating of the manually tested:
Phoenix Revelation II Anniversary Edition chess computer by Ruud Martin/DGT. This
Anniversary Edition of the Revelation II, features an updated hardware relative
to the ordinary Revelation II. The hardware for the Anniversary Edition is an 
Colibri iMX7D with 2 ARM Cortex A7 processors running at 1GHz. The software which 
we have used for the testing is the program Komodo 12.1 by Mark Lefler and
Larry Kaufman. 
The rating that has been reached after the first 100 games is 3177! This is a 
rating that is 253 points ahead of Hiarcs 14.1, which we tested formerly
on the ordinary Revelation II. It is clearly the strongest dedicated chess 
computer which we have tested so far and it has been able to perform admirably 
against the strong Q6600 opposition which it mostly has faced in our testing 
so far. 

Aside from producing more games with the already mentioned newcomers in the
rating list, we are at the moment testing Richard Pijl's - The Baron 3.45, 
and also Alex Morozov's - Booot 7.1. We also hope to have some more programs
ready for the next rating list.  

* This rating list was produced and based on the games/results that were finished 
on the first of May, but the publication of this rating list was unfortunately a 
bit delayed this time.
The testing has of course not stood still since then, and the games/results 
that has been played since this date will of course feature in the next rating 
list, which we plan to have out sometime in august/september.

This last rating list of 2023 consists of five new entrants. First one out 
is the latest version from Team Stockfish, named Stockfish 16. We have as usual 
used an opening book from Fauzi Dabat for the testing, and this one is called:
"Aggressive 5.6 by fauzi.abk". It's of course still early on in the testing, but 
Stockfish 16 has reached the very strong rating of 3582 after the first 200 
games and have taken over the second place in the rating list.
 
Even though the earlier Stockfish 15 gained 3 points since the last list, 
Stockfish 16 now has a gap of 9 rating points ahead of its former version. 
As Lc0 lost a considerable amount of points since the last rating list, the 
gap between Stockfish and Lc0 have now gone from 40 to just 4 points. It will 
surely be exciting to see how the rating will continue to fluctuate 
in the top of the list as more games will be played with all the top programs.

As incidentally mentioned, Lc0 wasn't able to keep up with its strong start 
in the last rating list and with more than 300 games added since last time,
its rating has been lowered with 24 points. Lc0 still holds the number one 
spot in the list, but now with a much smaller gap to its nearest competitor - 
Stockfish.

Our second newcomer on the list are Mark Lefler's and Larry Kaufmans's - Dragon
Komodo 3.3. It's extremely congested in the top at the moment and even though
Dragon Komodo has made a good impression in its first 248 games, it is at the 
moment only placed eigth in the list, with the rating of 3568. This is one
point behind Dragon Komodo 3, but also just five points behind Stockfish 15 in
third place, so more games will be needed to find out how it will fare in the 
absolute top of the rating list.  As opening book for Dragon Komodo 3.3, we have 
used Erdogan Günes's opening book: "Out10-35.bin". 

Third one out is Alex Morozov's - Booot 7.1, which after the first 200 games
have reached a rating of 3484, which is 9 points ahead of the 7.0 version. 
As opening book for Booot 7.1, we have used Sedat Canbaz's: "Perfect2021.abk".

Last but not least are Richard Pijl's - The Baron 3.45, which we have tested
on both our hardware platforms. As opening book we have used The Baron's own
opening book. On our 1800X hardware, The Baron 3.45 has reached a rating 
of 3081 after the first 160 games. This is at the moment 4 points ahead of 
the 3.43 version which we had tested earlier. On our Q6600 hardware, 
The Baron 3.45 has recieved a rating of 3053 after 360 games played.
This is 35 points ahead of the 3.43 version on the Q6600 hardware, so more 
games will be needed on the 1800X hardware to see if the smaller margin there
will get bigger as more games are played. 

Hope that you all have had a merry Christmas and a happy New Year
