Yes, I think Lime is too strong for the list!

Ok Richard, thanks.

949 of 1560 games played

Buggy engines still in the tournament (I will take a decision about them later)

- Joana DC by Juan Pablo Mendoza (when playing with white pieces does not accept opponent's short castle and loses by time. 5 losses on time out of 38 games.)
- Yoda 1.30 does not accept opponent's underpromotion to other piece different of a queen. (as this happens ocasionally, Yoda won't appear in this list in the next update. Anyway, it seems Yoda is going to be removed at the end of the cycle being at the top10 right now.)

Carlos

PS: I will travel in few hours, therefore I'll be far from my PC for some days. So, next update will be in 6 or 7 days.

[Carlos777]

I did see the top 2 Jabba and KMTChess in there and thought these engines were around 2000 and ones below them were probably around 1800. Hence my assumption 1800-2000.

Hi Swami,

Yes, I did not know too much about these engines at the time. As they had already played many games, I decided to keep them. Less strong engines will compete in the next cycle (this is the goal of this peculiar tournament ).

Best,
Carlos

Not working under Arena: (if someone has an idea on how to make them work, please reply)

ChessV 0.94

The engine command line for ChessV 0.94 has to be:

Code: Select all

ChessV_WinBoard "Orthodox Chess"

It seems that Arena cannot handle this (or people simply have not found out what they have to tell Arena to produce this command line when installing the engine).

Possible work-arounds are:

1) Put that command line in a batch file chessv.bat, and then install that batch file as an engine in Arena.

2) Make a ChessV .SGF file (saved-game file), say CHESS.SGF for the initial position of Orthodox Chess by saving from the stand-alone version of ChessV, or read the instructions that come with ChessV on how to make such a file for specifying variants, and follow those. Then install ChessV in Arena with the engine command:

Code: Select all

ChessV_WinBoard CHESS.SGF

so that you do not need the quotes around the argument that specifies the variant.

Even under WinBoard + PSWBTM I have to use the latter trick to make ChessV play Bird's Chess, as I have found no way yet to get the single quote in the variant name into the engine command line. With a bare WinBoard I can use /fcp={ChessV_WinBoard "Bird's Chess"}, but PSWBTM puts single quotes around the /fcp argument, and that is what makes WinBoard choke on it.

What is the approximate rating scale for '1700 or lower'?

In CCRL rating, I would estimate ChessMind at 1930-1950 Elo based on games against Surprise. But in other rating scales, the ratings are often lower.

However, based on games against humans, I would estimate ChessMind at 1700-1750 'human Elo'.

I think in the CCRL rating scale Jabba would have around 1980-2000 Elo or even more.

[Adam Hair]

This is great Carlos. I've been working on a rating list since August
and I am including engines of all strengths. Here is the bottom of my
list. I plan to include as many engines as I can make run on my computer
under Arena 2.01.

The only engine in this group that gives me problems is Testina2.2. It
loses some on time and sometimes makes illegal moves.

Not working under Arena: (if someone has an idea on how to make them work, please reply)

ChessV 0.94

The engine command line for ChessV 0.94 has to be:

Code: Select all

ChessV_WinBoard "Orthodox Chess"

Hi HGM,

I tried adding "Orthodox Chess" in the command parameters box without success, I will try your suggestions when I back home.

Thanks,
Carlos

Yes, people told me that Arena cannot handle quotes in the engine command line at all. But the sgf trick should work. I just tried it to play "Chess With Different Armies", because you could not even specify that from the command line without a new popup appearing to ask you which armies you want to pit against each other.

So what I did is just start a game of Chess with Different Armies by hand, select FIDE vs Color-bound Clobberers, and then immediately select "File -> Save Game". By giving the name of the save file as an arument, ChessV then plays that variant without problems under WinBoard + PSWBTM.

What is the approximate rating scale for '1700 or lower'?

I know that it is kind of ambiguous. As few tests have been done with low ELO engines (UEL is one of the few testing low ELO UCI engines, Open War and WBEC have done it too), there is no certainty about what engines should be considered 1700 ELO or less. Anyway, when I thought about 1700 ELO, I was thinking about human ELO.

However, based on games against humans, I would estimate ChessMind at 1700-1750 'human Elo'.

In that case, I'd be glad to test ChessMind in the next cycle if you agree.

I think in the CCRL rating scale Jabba would have around 1980-2000 Elo or even more.

Yes, as I said before Jabba is probably too strong for this tournament. I did not know its strenght before testing.

This is great Carlos. I've been working on a rating list since August
and I am including engines of all strengths. Here is the bottom of my
list. I plan to include as many engines as I can make run on my computer
under Arena 2.01.

Thanks Adam for this useful information, many of those engines will be tested in the next cycles.

OTOH, I am considering to increase the number of engines to be removed after the cycle ends to 20 (instead of 15) to speed things up. More engines would be tested in this way (new 20 engines.) If someone disagree, let me know your reason.

Regards,
Carlos

Hi Carlos,

Thanks for including Myrddin in your tournament. The version you have chosen was rated 1600-1700, so it does fit your tournament's criteria. However, Myrddin is definitely still in development, and the latest version is about 250-300 points stronger than the version in your tournament.

Someday, Myrddin will indeed be forgotten. But hopefully not for a while yet.

Thanks again!
