For this October Rating list we can present five new Chess Computer programs.
First out is Stockfish 9 by Tord Romstad, Marco Costalba and Joona Kiiski. For
the testing of this program, we have used the updated free opening book from 
Fauzi Dabat, called "Aggressive 3.5 by Fauzi.abk". As you can see from the 
Rating list, this very strong combo has managed to break the 3500-barrier for 
the first time in our Rating list! The rating of 3502 after 482 played games
is a whopping 72 point stronger than it's former version which we introduced 
in the list back in January this year. 

The next new version we have in this list, is the Stockfish 8, which 
we now have enough games with on our older Q6600-platform. After 280 played 
games it has reached a very strong rating of 3416, trailing it's 8-sibling on 
our fastest 1800X-hardware by only 14 points! More games will be needed to 
see if this difference will hold steady. We have of course used the same 
opening book for the testing of Stockfish 8 Q6600, as we have used when we
tested Stockfish 8 on the 1800X, that is the "Aggressive 3.2 by Fauzi.abk".

The next new entrant was one of the contenders in the ICGA World Chess
Championship, which was held here in Sweden/Stockholm in July this year. 
This program is called Booot 6.3.1, is made by Alex Morozov and 
became runner-up behind Komodo in the Unified Hardware category of the 
Championship! Its rating of 3347 after 320 games are indeed very strong and
especially considering it hasn't support for Endgame Tablebases like the 
other programs which we have tested on our Ryzen 1800X-hardware.
Alex wanted us to use the same book in our testing, as he used in the 
championship, that is the free "perfect2017.abk" opening book by Sedat Canbaz. 

The last entrant on our ratinglist was also a contender in the ICGA
Championship, and it is Richard Pijl's - The Baron. On our fastest hardware - 
the 1800X, The Baron 3.43 has reached a rating of 3115 after 320 games. 
We have also tested it on our Q6600-hardware and there it has reached a 
rating of 3026 after 400 played games.

It uses its own opening book and tablebases on our Q6600 and 1800X machines,
but has had some tablebase issues with 5 piece Endgame Tablebases like the 
standard we have on our Q6600 machines. This has affected its performance  
somewhat. According to Richard, this issue is corrected for future releases 
of The Baron, so we hope to be able to test an updated version in an upcoming
Rating list. This issue hasn't affected the testing on the 1800X-machines, as
it hasn't any issues with the 6 piece Endgame Tablebases we have as standard 
on this hardware.

Compared to our former Rating list, Komodo 11.01 Q6600 gained 7 points, Pro
Deo 2.1 YAT A1200 gained 6, while Spike 1.4 Q6600 and the Android version
of Chess Genius 3 gained 4 points. Komodo 9.1 Q6600 lost 10 points, Wasp 2.01
on the A1200 lost 8, Revelation Ruffian lost 6 and Hiarcs 14 A1200 lost 5 
points. 

We have begun testing of John Stanback's latest Wasp version for our next 
Rating list, and we hope to also begin testing of a more recent version of 
both the ordinary Komodo and its Monte Carlo Tree Search &#40;MCTS&#41; version. 
We will also hopefully be able to add both Stockfish 9 and Booot to our 
testing on the Q6600 hardware level. 

The next list will be out approximately in December/January depending 
on how many new games we will have until then.

On our latest February rating list we can present six new Chess Computer 
programs. First out is the winner of all three classes at the ICGA World
Championship that was played in Stockholm/Sweden last summer - namely Komodo.
Komodo is written by Mark Lefler, Larry Kaufman and the late Don Dailey.
The version we have tested is named Komodo 12.3 and it has achieved a very 
strong rating of 3456 after 640 games played on our 1800X hardware level. This
is 59 points stronger than the 11.01 version we tested last time. We have used
Komodo's opening book by Erdogan Guenes for the testing.

The next new version we have on this list is Stockfish 9, which now have 
sufficient amount of games on our Q6600-hardware level. After the 
first 200 games it has reached the rating of 3446. This is 28 points stronger
than Stockfish 8 on the same platform, and is 48 points lower than the same
version on our 1800X hardware. We have of course used the same opening book 
as we previously used on our 1800X hardware, when we tested Stockfish 9; that
is the free "Aggressive 3.5 by Fauzi.abk" opening book by Fauzi Dabat.

We have also got enough games with Booot 6.3.1 on our Q6600 hardware to be
able to introduce it on the list. The rating is 3280 after the first 320 games.
This is 72 points lower than the 1800X version which we introduced on the
last rating list.

Just in time for this rating list, we could also present an early rating of 
the latest Arasan program by Jon Dart. We have tested it on our 1800X hardware,
with it's own included opening book and it has reached a rating of 3269 after 
the first 127 games. More games will be needed to get a more reliable rating, 
but the rating of 3269 is still 269 points stronger than the last Arasan
version we have tested! Even though some of the difference are due to 
the fact that we tested the 17.2 version on our Q6600-hardware, the 
performance gain from improvements made in the software is impressive.

Next out is the Wasp 3.0 program by John Stanback. We have played 642 games
with Wasp 3.0 on our 1800X hardware, and it has reached the rating of 3218. 
This is 59 points stronger than the 2.01 version which we introduced in our
rating list in January 2018. We have used the free opening book by Sedat
Canbaz, called "Perfect2017.abk" for the testing of Wasp 3.0. 

Last out in this rating list is the manually tested "oldie" - the dedicated
Mephisto London 68000 chess computer. This is a computer which we never got
to test back in the days, but now are able to finally introduce in the 
rating list, 23 years after it was introduced back in 1996! 
The Mephisto London is the program of Richard Lang and uses the module 
hardware for the old Modular/Exclusive/München boards. It features an 
Motorola 68000 processor at 12 MHz and uses 512 kB RAM for hash-tables.
The rating after the first 100 games is 2035 and this is 18 points stronger
than the Berlin 68000, which previously was the strongest Lang program on 
the 68000 hardware in our rating list.

Compared to the last rating list, Deep Hiarcs 14 1800X gained 8 points and
Novag Star Sapphire gained 6 points. Meanwhile The Baron 3.43 1800X lost 
20 points, Millenium ChessGenius lost 9 points and Stockfish 9 1800X lost 
8 points. 

For our next list we will focus on getting more games with Komodo 12.3 on 
our Q6600 hardware and also Arasan 21.2 on both the 1800X and Q6600 level. 
We will also begin testing of Stockfish 10, Wasp 3.5 and hopefully also 
the Monte Carlo Tree Search &#40;MCTS&#41; version of Komodo. 
We are also manually testing both the Millenium ChessGenius Exclusive and 
the latest Millenium The King Exclusive now.

Our next rating list will probably be out before summer.

On this July ratinglist of 2019, we can present eight new entrants.

First out is the new leader in the rating list, and the first to break the 3500-
barrier in our rating list. It's Stockfish 10 by Marco Costalba, Tord Romstad 
and Joona Kiiski. As with the former versions, we have used the free opening book
from Sedat Canbaz for the testing, and this time it has been the 
"Aggressive 4.0 by Fauzi.abk". After 577 games it now leads the list by a margin
of 36 points in front of its older version, and with the rating of 3529!

Second out and still early on in the testing, is the latest program by Mark Lefler
and Larry Kaufman. It has placed itself third in this list with the rating of 3482. 
This is 28 points stronger than the last Komodo-version we have tested. As in the
testing of the 12.3-version, we have used Erdogan Guenes opening book. This version
is the "normal" version which can be compared to the older versions we have tested.

We have also tested the Monte Carlo Tree Search-version of Komodo, named MCTS, for 
the first time. We have used the same opening book for this testing. Even though
it's also early on in the testing, it has achieved a strong rating of 3424 after 
205 games played. It trails the normal 13.02-version by 58 points, but are stronger 
than most other programs outside the latest Stockfish/Komodo range and places 
itself on the eight spot in the ratinglist.

Last one out of the programs which we have tested on our 1800X-platform, is
John Stanback's - Wasp 3.5 program. It has achieved a rating of 3235 after the 
first 480 games played, and this is 22 points stronger than Wasp 3. 
Contrary to the other two Wasp-versions we have tested &#40;2.01 and 3&#41;,
Wasp 3.5 now includes an own opening book, which we have used for the testing. 

As can be seen from the rating list, we now also have enough games to be able to
present four new additions to the Q6600 hardware level. First one is Stockfish 9,
which has gotten a rating of 3445 after 431 games played. This is 48 points lower
than the version we have tested on the AMD Ryzen 7 1800X hardware level, but is
also the strongest program we have ever tested on the Q6600 platform! 

With a slim margin of only 2 points lower than Stockfish 9, we have now the 
Komodo 12.3 on our Q6600 hardware. It has managed to get a rating of 3443 after 
the first 280 games. This is only 11 points lower than the same version on the 
1800X and 110 points in front of the 11.01 version on the Q6600!

Next up is the program of Jon Dart - Arasan 21.2, which we now have 152 games
with. It's also an early bird which barely made it to this list, but its rating
after the first couple of matches are 3250. This rating is 30 points lower than
the same version on our 1800X platform, but a whopping 249 points stronger than 
the 17.2 version which we also tested on our Q6600 level!

Last one out and extremely in time for this list, was Wasp 3.5 on our Q6600. 
It has achieved a rating of 3174 after the first 112 games, which is
61 points behind the 1800X version, and 109 points stronger than the last 
Wasp-version &#40;2.01&#41; we have tested on the Q6600. 

Notable gains/losses from the last list was&#58; Arasan 21.2 1800X, which gained 11
points, Booot 6.3.1 Q6600 gained 8 points and Booot 6.3.1 1800X gained 5 points.
The programs which lost most points was&#58; Mephisto London 68000 which lost 23
points, The Baron 3.43 1800X lost 7 points and Stockfish 8 Q6600/Wasp 3 1800X 
lost 5 points each. 

For the moment we are manually testing both the Millenium ChessGenius Exclusive, 
the Millenium The King Exclusive and also the previously untested oldie Mephisto 
London 68020. We will be able to introduce the ChessGenius Exclusive on our next 
rating list which we plan to have out in the end of summer or as soon as this 
computer have enough games.

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 &#40;WCCC&#41; and World Software Chess Championship &#40;WSCC&#41; 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&#58; 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&#58; It was Fauzi Dabat's opening book 
which we have used for the testing of Stockfish 10, and not Sedat's. D.S.

This first list of 2020 will be dedicated in honor of the late Tony Hedlund. *

For this new rating list we can present four new entrants. Three PC-programs
and one dedicated chess computer.

First out is the new leader on our rating list, namely Stockfish 11. For the
testing we have used the free opening book by Fauzi Dabat, named&#58;
"Aggressive 4.5 by Fauzi.abk". This strong combo has achieved a very impressive
rating of 3558 after 330 games played and this is 33 points ahead of its older 
version.

We have also got enough games to be able to present a later version of the 
Monte Carlo Tree Search-version of Komodo, by Mark Lefler and Larry Kaufman.
The version tested this time is 13.2.5. After the first 200 games the 
rating are 22 points stronger than the last version tested &#40;13.02&#41;. As before
we have used the Komodo opening book by Erdogan Gunes for the testing.

We are also able to present the formerly tested Vajolet2 2.8 by Marco Belli on
our Q6600-hardware this time. After 320 games played on this hardware, it has 
reached a rating of 3280. A rating which is just 19 points shy from the version
we have tested on our 1800X platform. More games against stronger opponents will
be needed to see if this margin will hold.

Last but not least is the manually tested chess computer which goes by the name&#58;
Millennium The King Exclusive. A dedicated chess computer which is manufactured
by the company Millennium 2000 GmbH. Similar to the ChessGenius Exclusive, it 
has an ARM Cortex M7 processor which is clocked at 300 MHz. The program used in 
this chess computer is the highly regarded King-program by Johan De Koning. 
We have tested versions of his programs before, both in dedicated chess computers
and as engines in the well known Chessmaster-series. After the first 104 games 
it has recieved a very strong rating of 2543! A rating which is 22 points 
stronger than the Chessmaster 8000 which we tested on the K6-2 450 MHz back in 
the days, and 345 points ahead of the King 2.0 version which we tested in form
of the dedicated Chessmachine-card for PC. 

Most points gained since last list was +15 for Arasan 21.2 1800X, PF 3 Glaurung
gained 11 points and Deep Hiarcs 14 1800X gained 5 points. ChessGenius 3 on our 
mobile Android-platform lost 10 points and Wasp 3.5 1800X lost 8 points.

We have begun testing of the new Komodo-version, the latest versions of Booot
and Wasp. We will also soon begin the manual testing of DGT/Ruud Martins&#58;
Revelation II Anniversary Edition. We hope to have the next list out sometime in
the beginning of autumn, depending on how the testing goes until then. 

Stay safe out there and hope to meet you all in autumn again.

Lars Sandin

Thank you so much for all that you do, and so sorry for the passing of Tony. He did amazing things with the SSDF for so long.

Quick question. I noticed that Revelation 2 Stockfish is not on the list. I understand that Stockfish 6 is a native engine on the Revelation 2, and I'm understandably curious as to how it performs. For that matter, I suppose the rest of the Revelation 2 engines (except for HIARCS, which is on the list). Are you planning to test them?

Thanks for the kind words! Yes, Tony was a great guy and he will be missed dearly.

The meeting I recently started (and will publish the games from today) will be the last meeting with the Rev II in the original form before the upgrade to the Anniversary Edition. It won't be a full 20-game match, as I will prioritize testing the A.E. when it arrives. This will mean that the Rev II Hiarcs 14.1 will be the only engine tested on the original 800 MHz.

I have tested most of the other engines on the Rev I though. My last project was to test the Toga 1.2, but I had to interrupt this testing because of some strange bug in Toga which made it hard for me to continue. So just now I am playing with the Rev I Deep Sjeng 3.0 against the Millennium The King Exclusive, and the games will follow shortly.

This is the last list of the pandemic year 2020 and features some new and
interesting entrants.

First out is team Stockfish with their latest edition of the Stockfish engine,
namely Stockfish 12. This version uses a neural network architecture &#40;NNUE&#41;, 
which now can be run on ordinary processors instead of Graphic cards. It has 
been tested with the latest free opening-book of Fauzi Akram Dabat, named&#58;
"Aggressive 4.7 by fauzi.abk". After the first 257 games, this strong combo, 
has achieved an impressive rating of 3573, an improvement of 26 points over 
the previous version, and it keeps the leader spot in our list!

Next one out is the Komodo version from Mark Lefler and Larry Kaufman, named
Komodo 14. This version was tested with the opening book of Erdogan Günes&#58; 
"out5-35.bin", a book which we also have used previously when testing earlier 
Komodo-versions. Komodo 14 has achieved a rating of 3466 after 320 games.
It doesn't show a clear improvement over the earlier 13-versions we have
tested and positions itself between the 13.1 and 13.02 versions at the moment.
More testing will be needed to see if this will hold, or if it will gain some 
rating when more games are played.

We can also present another version of Komodo in this rating list, namely
the latest Komodo-version, called&#58; Dragon by Komodo. This is the first Komodo
version which uses the NNUE-technique, and the gain in strength from the 
previous version is huge. After the first 250 games, its rating is 3564! 
This is 95 points over the 13.1 version and it now trails Stockfish with a 
margin of only 9 points. Dragon by Komodo has been tested with Erdogan 
Günes opening book&#58; "out10-35.bin".

For this rating list we can also present the latest release of the Booot
engine by Alex Morozov, named Booot 6.4. We have been testing this engine 
with Sedat Canbaz opening book&#58; "perfect2019.abk". After the first 280
games, the increase over the 6.3.1 version is 13 points, and the rating 
is now 3370.

We have also tested the engine&#58; Wasp 4 by John Stanback for this rating 
list. We have tested it on both our hardware levels. We have used its own 
opening book for the testing. On our 1800X-platform it has achieved a 
rating of 3257 after the first 240 games. This is an improvement of 37 points
from the earlier 3.5-version. On our Q6600-platform it has gained a rating 
of 3209, and this is 40 points stronger than the Wasp 3.5-version which we 
tested on the same Q6600-hardware. 

Since last time, Revelation Deep Sjeng 3.0 gained 7 points. Notable losses 
was Millennium The King, which lost 16 points and Stockfish 11 which lost 
11 points.

We are at the moment testing the MCTS-version of Komodo, Fabio Gobbato's 
engine&#58; Pedone, and we will hopefully also be able to present a rating 
of the old dedicated chess computer London 68020 on our next rating list.

For this summer rating list we are able to present 9 new entrants.

First one out is also the first chess program we have ever tested for the 
rating list which have utilized a graphic card. The new number one on this
rating list is Leela Chess Zero, which have recieved an impressive rating of
3581 after 320 games played. We have tested Leela Chess Zero with a  
Nvidia RTX 3060 Ti graphic card. We have used the Lc0 0.26.3 version and have
used the 30 blocks x 384 filter net with the number 67362. As opening book we
have used the free "Perfect2021.abk" opening book by Sedat Canbaz.

Trailing just 8 points below, with a rating of 3573 after 320 played games,
is the 13th version of Stockfish. Like its former version, it uses 
neural network architecture (NNUE). We have chosen to omit 
the NNUE-nomenclature from the name, since NNUE is the default and strongest
setting. We have used the latest free opening book by Fauzi Akram Dabat for 
the testing of Stockfish 13 and it is named "Aggressive 4.9 by Fauzi.abk". 

In this rating list we can also present two new MCTS-versions of Komodo, both
utilizing the NNUE-technology. The first one which we tested was 
Dragon Komodo (1) MCTS, and due to some difficulties with the AVX2 version, 
we had to test the non-AVX2 version of Dragon Komodo (1) MCTS. 
After 280 played games and with a rating of 3420, it has positioned itself 
3 points ahead of its 13.2.5-version, which was non-NNUE, and also 137 points 
below its non-MCTS version of Dragon Komodo (1). The gap between the two 
(non-MCTS/MCTS) was not as significant when we tested the 13.02 version of 
Komodo, and back then it was 64 points between the two versions.

We have also tested the new Dragon Komodo 2 MCTS-version from Mark Lefler and
Larry Kaufman. This version seems to perform better and we have also have had
no problems in getting the AVX2 version to work this time. It is relatively 
early on in the testing, but Dragon Komodo 2 MCTS has recieved a rating of 3503
after the first 160 games played. This makes it 83 points stronger than the 
first version and also just 54 points shy of its non-MCTS version of Dragon
Komodo (1). We have used the same opening book for the testing of both
Dragon Komodo MCTS-versions, namely Erdogan Günes opening book "out10-35.bin".

On this rating list we can also present four new entrants from Fabio Gobbato,
tested on both the 1800X and Q6600 hardware levels. First one we tested was the
Pedone 2.1 version. This version was non-NNUE and has managed to get a rating 
of 3222 after 240 games on our Q6600 level. On our 1800X level, it has recieved
a rating of 3305 after 280 played games. The difference between the two hardware
levels is 83 points. 

Next one out was the Pedone 3.0 version, which uses NNUE in its search. Likewise 
with other NNUE-programs on the list, we have chosen to omit the NNUE-nomenclature, 
since this is the strongest setting for their respective versions. Pedone 3.0 has
recieved a rating of 3399 after 240 games played on our 1800X level, and a rating
of 3317 after 200 games played on the Q6600 level. The difference between the two 
hardware levels are nearly the same as the 2.1 version and it is 82 points.
The gap between the non-NNUE version of 2.1 and the NNUE-version of 3.0, is 
95 points for the Q6600-level and 94 points for the 1800X-level! We have used 
Pedones own opening book for the testing of version 2.1 and 3.0.  

Last one out is an oldie which at last has managed to get on the rating list 
with some manual testing. The dedicated chess computer Mephisto London 68020 
at 12 MHz, is a module which can be used in Mephistos modular boards. The modular
boards included the Modular/Exclusive/München and Bavaria wooden chess boards.
The software in the London 68020 is the Genius 3.0 program by Richard Lang, which
on a PC (Pentium 90 MHz) managed to beat Garry Kasparov in a rapid game 1994 in 
London. After the first 115 games, London 68020 has managed to get a rating 
of 2103. This is nearly 100 points stronger than the 68000-version and also 91
points weaker than the London 68030 version at 33 MHz. It trails the Mephisto
Berlin Pro 68020 at 24 MHz, with 25 points, but it is the second strongest 68020
program we have ever tested, 39 points ahead of its Vancouver 68020-version. 

We are at the moment testing several different programs which barely missed
this rating list, but will feature in the upcoming rating list which we plan
to release as soon as they have enough games to be presented. Hopefully our
next list will be out sometime in the autumn.

Hi Lars,

I do not see the DGT Centaur in the list. Are you planning rating games for the Centaur at Expert level?

Best regards, Paul

Hi Paul,

I don't believe that the DGT Centaur has a tournament level suitable for our test conditions, that is a time setting for 2h/40 moves and then 1h for each 20 moves. I also think it would be hard to correctly rate a computer like the DGT Centaur, which to my knowledge, is adapting its strength to the opposition. No doubt that it is a strong computer, but it would be hard for us to test it because of these two factors.

Best regards
Lars

Hi Lars,

Yes the Centaur seems to have only "game in xx minutes" levels, from 2 to 90 minutes. Very strange.
But in Expert mode it does not adapt its strength, plays at full power.
Anyway indeed hard to test for you.

Hi Paul,

How does the Centaur handle the openings when playing on Expert mode? I guess it has an internal opening book which it is following on all modes (even though it seemingly "thinks" and takes some time when playing the moves)? How does it handle variety on Expert Mode? Similar to other chess computers with an opening book or does it play more or less the best move (from book) all the time? Just curious as I haven't seen the computer IRL.

Yes, it will be tough to test it if it doesn't include the level which we need.

Best regards

Hi Lars,

Yes, it seems to deliberately take some time for each move, so not to "frighten" the human opponent with an immediate response

.
I do not have the Centaur myself, I get the info from a chess-friend who owns it.
But I will ask him for more info about the opening book.

Regards, Paul

This last list of 2021 and first list of 2022, will be dedicated in honor of the
late Guy Haworth.
 
On this new years list, we can present seven new programs on our two hardware
levels. 

First one out is Mark Lefler and Larry Kaufman's latest version of Dragon  
Komodo, named 2.51. We have initially tested the non-MCTS version and after 
the first 240 games it has reached a rating of 3569, that is 22 points stronger
than the last non-MCTS Dragon Komodo we tested. It is now just four points 
behind the leader from the last rating list - Lc0. It is also nine points below
Stockfish 13 - which now has taken over the leader spot in the rating list. 
Dragon Komodo 2.51 is now more than 100 points stronger than the best non-NNUE 
version of Komodo we have tested! As before we have used the opening book 
"out10-35.bin" of Erdogan Gunes for the testing of Dragon Komodo.  

Next one out is the latest creation from team Stockfish, namely Stockfish 14. 
After the first 202 games it has reached a rating of 3554, which is 24 points
behind Stockfish 13 in first place, and 4 points behind Stockfish 12.
For the testing of Stockfish 14 we have used the opening book by Fauzi Dabat 
named "Aggressive 5.0 by Fauzi.abk". More games will probably be needed to
stabilise the rating against the other engines in the top, lower the error 
bars and see if it will be able to supersede the older version as more games
are played.

We have also tested two new engines from Jon Dart, named Arasan 22.3 and the 
neural network architecture (NNUE) version named 23.01. For the testing of 
these two engines, we have used Arasan's own opening book. Arasan 22.3 has 
reached the rating of 3363 after the 240 games. This is 78 points stronger 
than the last Arasan 21.2 version we have tested. The NNUE version: 
Arasan 23.01, has then gained a further 74 points on that, resulting in the
rating of 3437 after the first 240 games.

We also have the latest (and last) free Pedone-version in this rating list. 
It is Pedone 3.1 by Fabio Gobbato. Like the 3.0-version of the same program,
it uses NNUE in the search. We have tested it on both our hardware levels. 
On the 1800X - Pedone 3.1 has reached a rating of 3423 after 220 games 
played. On the Q6600 hardware, Pedone 3.1 has achieved a rating of 3376 after
260 games. The difference between the two hardware is 47 points, and 
Pedone 3.1 on the 1800X is 37 points stronger than Pedone 3.0 1800X. 
On the Q6600, the difference between Pedone 3.1 and 3.0 is 53 points. 
We have used Pedone's own opening book for the testing of Pedone 3.1.    

We can also present a rating of Alex Morozov's latest Booot program, named 
Booot 6.5. We have tested this program on two of our hardware levels. On
our 1800X hardware, Booot 6.5 has received a rating of 3432 after 200 games. 
On our Q6600 hardware, Booot 6.5 has reached a rating of 3359 after 240 
games. The difference between the two different hardware is 73 points. 
The 6.5-version is 64 points ahead of the formerly tested Booot 6.4 
on the 1800X and on the Q6600, the difference between Booot 6.5 and 
Booot 6.3.1 is 68 points. We have used Sedat Canbaz's "Perfect2021.abk"
for the testing of Booot 6.5.

We are also able to welcome a Swedish newcomer in this rating list! 
Probably the first Swedish program in the list after Per Ola Valfridsson's - 
Ruffian, I guess?  
It is Martin Danielsson's engine: Marvin 5.1.0, which we have tested on both 
our hardware levels. We have used Marvin's own opening book for the testing. 
Marvin is from the 5.0.0-version a neural network architecture (NNUE)-program.
On our 1800X hardware, Marvin 5.1.0 has reached a rating of 3324 after 
240 games. On the Q6600 hardware, Marvin 5.1.0 has gotten a rating of 
3225 after the first 147 games. The difference between the two hardware is 
just shy of 100 points. 

Last, but not least, is the two Wasp-programs from John Stanback. The first one 
is Wasp 4.5, which uses ordinary search, and has received a rating of 3264 
after the first 140 games. This is nine points ahead of the formerly tested 
Wasp 4. Wasp 5.0 has introduced NNUE in its search. This has proven to be 
valuable for Wasp (as for other NNUE engines), and Wasp 5.0 1800X has 
received a rating of 3378 after the first 120 games. Albeit it's early in 
the testing, the difference between the two versions is now 114 points at 
least!
