August 23 Update Correction

As it turns out, the only thing correct about my update yesterday were the ratings I posted. There were problems with the database, and with the statistics generated from that database. So, I have made the corrections and uploaded a corrected PGN.

Also-Rans Ratings List Update - August 23, 2012

The Also-Rans list has been updated. I have also updated the statistical information and the database. The link to the Also-Rans database can be found at the ratings page.

Ed Schröder's Donationware

Ed Schröder, the author of chess programs such as Mephisto MM IV and MM V, Rebel, and Pro Deo, has decided to make his older Rebel PC chess programs Winboard and UCI (via WB2UCI) compatible and provide them as donationware. As stated at Wikipedia and Ed's site, donationware is a licensing model that supplies fully operational unrestricted software to the user and requests an optional donation be paid to the programmer or a third-party beneficiary (usually a non-profit). Ed's request for donations is for raising money to create a "World Championship" competition among the top-rated chess engines. So feel free to download the versions of Rebel that Ed converts and makes available. If you can, please donate 1 Euro (via PayPal) for each engine you download.

Also-Rans Update - August 8, 2012

A ratings list that is in continued fluctuation is of no use to anybody. Having said that, I have made one more change (and, with high probability, the last change) to how the Also-Rans list is computed. I have decided to compute the ratings from a database of games consisting of the CCRL 40/4 pure, single CPU database and the Also-Rans games. The list shall be calibrated so that Brutus RND, a random mover (chooses its next move at random from the legal moves available), has a rating of 0 Elo. The Also-Rans list will consist of all engines outside the top 200 engines of the combined database. Since the CCRL ratings may be computed in this manner within the next year (more games are needed to meet the CCRL standards), the Also-Rans list will finally be stable.

Chess for Mobile Devices - ChessGenius

ChessGenius - A program written by the legendary Richard Lang in the 1990's, originally for MS-DOS, that has been ported to Palm, Windows Mobile, Bada phones, Symbian phones, iOS, and Android devices.

Richard Lang is famous for winning the World Microcomputer Chess Championship 10 times, from the mid 1980's with Mephisto to the mid 1990's with ChessGenius. ChessGenius became the first chess program to beat a world champion (none other than Gary Kasparov) at a non-blitz time control, and obtained a rating of 2795 in the same tournament (1994 Intel World Chess Grand Prix), while running on a 100 MHz Pentium PC.

The Long History of Mephisto - Part 1

Mephisto is a name long associated with chess playing mechanisms. In 1878, Charles Godfrey Gümpel, a maker of artificial limbs, displayed a chess playing pseudo-automaton named Mephisto in London. It was controlled remotely by electromechanical means, as opposed to hiding a human operator. In 1889, it was shown and operated at the Exposition Universelle of 1889 in Paris. After the exposition, it was dismantled and its ultimate fate is unknown.


Mephisto automaton

Anyone who wants to read a bit more about Mephisto can read batgirl's posts (Mephisto the Magnificent, HOW MEPHISTO WAS CAUGHT, Mephisto - Promotional Material, and Mephisto revisited) in her blog "Le blog de la Batgirl at Chess.com.


However, Gümpel's invention is not the only chess playing mechanism named "Mephisto". It is also the name for a long line of dedicated chess computers, first manufactured by Hegener & Glaser in 1980. Several renowned authors have been associated with the Mephisto line, including Frans Morsch (best known for Fritz), Ed Schröder (author of Rebel and Pro Deo), and Richard Lang (author of Chess Genius). Hegener & Glaser was acquired by Saitek LTD in 1994. Saitek continued manufacturing the line, and still does to this day.

Update - July 19, 2012

I am sorry for the lack of new material. I am trying to reformat a couple of pages to improve navigation of the information. I am also working on a page that is a tutorial for running engine matches in various various GUIs. Though it is not completed, I will be uploading the tutorial soon. I also expect to completely update the Also-Rans list this weekend.

Still Working Regards :-),
Adam

CountryChess

Geert Maeckelbergh, a Belgium computer chess enthusiast, runs an interesting chess engine tournament called CountryChess.

From Geert's front page:

In the first stage, chess engines of the same country will play a double round-robin tournament. The winner of each country competition meets other country winners in qualification matches or in the Champions League, according to its place on the country ranking list. Top ranked countries will be represented by 2, 3 or even 4 engines in the Champions League.

About me:
My name is Geert. I live in Belgium and I am visually impaired. I prefer to update an easy blog, friendly for a blind user. My goal is to organize tournaments and to share the games and results. I don't like wasting time on unaccessible webdesign programs. So don't expect a perfect lay-out; since my brail display is able to read the texts, you'll probably have no troubles to read them as well :-).

My English is not perfect at all. If you see language errors or other mistakes, don't hesitate to send me an e-mail.

Enjoy!

Geert also posts results from time to time at the Tournaments and Matches subforum at TalkChess.

Thanks, Geert, for sharing your matches with the community.

The Chess System Programs of Chris Whittington

I completely botched the portion of my previous post that concerned Chess System Tal. As my penance, I have committed myself to write an in-depth post about the Chess System programs.


The Chess System programs were created by Chris Whittington in the 1990's and marketed by his company, Oxford Softworks. Their creation was guided by Whittington's philosophy that encoding knowledge into a chess program is much preferable over fast and deep searches.

Free DOS Chess Programs

In many people's opinion, the DOS chess programs from the 1980s and 1990s are more enjoyable to play against than modern programs. Possible, this is because there was more emphasis on style and a little less on strength. Or perhaps it is simply because the moves they played were less mystifying than today's juggernauts. Several have been described to play in a human-like manner, such as the revered Chess System Tal II * (authored by Chris Whittington):

Chess for Mobile Devices : Droidfish

Droidfish (Free) : A chess program for Android devices developed by Peter Österlund, author of Texel (formerly CuckooChess). The main engine for the program is Stockfish (authored by Marco Costalba, Joona Kiiski, and Tord Romstad).

Chess for Mobile Devices : Stockfish Chess

Stockfish Chess (Free) : A chess program developed for iOS devices by Tord Romstad, the author of Glaurung and one of the authors (along with Marco Costalba and Joona Kiiski) of Stockfish (the active continuation of Glaurung). The engine for the program is a port of Stockfish, one of the strongest chess engines available.

Alan Turing

Alan Turing (June 23, 1912 – June 7, 1954) was a British mathematician and logician who is considered the father of computer science and artificial intelligence (AI). Among his accomplishments were: an independent proof that Hilbert's Entscheidungsproblem was, in general, unsolvable; the invention of the idea of Turing machines; the formulation of the halting problem; played an integral part in breaking the German ciphers in WWII; presented the first design for a stored-program computer; discovered LU decomposition (used to solve matrix equations); invented the idea of the Turing test to determine if a computer could successfully imitate a human; and contributed work in the field of mathematical biology.

Novag Super Constellation

The Super Constellation, also known as the Super Connie, was a dedicated chess computer manufactured by Novag and first sold in 1984. The chess playing code was written by the acclaimed computer chess programmer Dave Kittinger, who was also known for writing the engine for ChessMaster 2000 and his DOS program WChess. Scott McDonald, an American chess master, assisted Kittinger.

Chess for Mobile Devices: CHESS PRO

CHESS PRO ($9.99): A chess program created by Christophe Théron for iOS devices. The engine within the program is Christophe's famous Chess Tiger.

Chess for Mobile Devices: Chess For Android

This is inspired by my friend Julien MARCEL, who has been posting about chess programs for iOS devices at TalkChess. I will attempt to cover chess programs for iOS devices (using Julien's TalkChess posts) and chess programs for Android devices.

The first program I will post about is the Android program I use and love:
