Update

Noomen book

August 2016

 

Here is a brand new update of my latest book, Noomen.ctg, with many corrections, additions, improvements, novelties and a few extra lines.

 

Please make sure always to use the following options, see Book Options (below picture how to).

 

  1. Tournament Book should be switched ON
  2. Minimum games should be set to 3
  3. Up to move should be set to 100

 

Not using these settings might result in a lot of weak(er) moves being played.

 

As usual, a big "thank you" to all the people who helped me to produce this new version. Enjoy!

New Noomen book

May 2016

 

After 6 years a brand new, varied and super strong CTG opening book by the hand of Jeroen Noomen, the Dutch specialist who in the past also was the author of the books for: Mephisto Polgar, Mephisto Milano, Openings module HG550 for Mephisto MM V, Mephisto Vancouver, Rebel / Pro Deo, Chess Tiger and Rybka.

 

The new book contains the latest developments in opening theory and is further enriched and checked with computer analysis. In my testing it showed a remarkable increase of playing strenght in comparison to Jeroen's last art work of 2009, the Rybka 3 opening book. How much? Find out yourself.

Content Gambit Package

------------------------------

 

1. Noomen Gambit Lines 2015.pgn: a large testsuite for engine-engine testing, with gambits only.

 

2. Noomen Sharp Gambits 2015.pgn: a small testsuites (30 positions) containing the sharpest and most interesting gambits from Noomen Gambit Lines.

 

3. GambitLines.abk: the Noomen Gambit Lines pgn-file imported into an Arena abk-book, also meant for engine-engine testing. NOTE: if you are going to use this book in Arena, make sure that both

engines use this gambit book! It is not useful to test this book against other books, as it contains only the 247 gambit lines from the Noomen Gambit Lines pgn.

Polyglot opening books

 

The polyglot book format is the most wide spread format in use by chess engines.

PRODEO.BIN

 

We converted the ancient (2000/1) REBEL (ProDeo) book to polyglot format. While old it is still a Noomen book and thus good.

 

A 200 game match confirmed it. We pitched Stockfish 7 with the REBEL book against the book of 2 times YAT winner Andscacs and the result was convincing.

 

SF7 (ProDeo.bin) - SF7 (varied.bin) 111.5 - 88.5

DC.BIN

 

As second step we added the analysis work of Dann Corbit and Les Fernandez to the ProDeo.bin book. This has resulted in a Polyglot opening book with 111 million moves. This book did very well in the YAT-2 tournament.

 

Another 200 game match, now with the Noomen Corbit cocktail also ended positive.

 

SF7 (DC.bin) - SF7 (varied.bin) 109 - 91

Polyglot Books can be edited by Winboard and Scid.

 

Realize that making changes to the big DC.BIN book the saving may take considerable time.

Third step

adding even more to it

 

Now as in ProDeo YAT we want to enrich the 2 (above) Polyglot books (ProDeo.bin and DC.bin) further with the valuable data of CCRL 40/40 games played by high rated engines. For that purpose we have created 7 elo based polyglot books from the CCRL data, elo 3200, 3150, 3100, 3050, 3000, 2950 and 2900 and merged into ProDeo.bin and DC.bin. To clarify, the elo-3200 book only contains data from 3200+ rated engines, the elo-3150 book only contains data from 3200+ rated engines, etc. resulting in the following updates of the ProDeo.bin polyglot book.

It's important to carefully consider what book to use. If you have (want to use) a 3000+ elo rated engine and you take ProDeo-2900 as opening book that might turn out not so wise because it might play moves from 2900 rating engines also as book move. It makes more sense to use ProDeo-3100-3150-3200. A safefy margin of 100 elo is adviced although it's a educated wild guess. Only testing will tell.

 

Therefore, for top-engines (although not impossible) it will be much harder to profit from the CCRL data, for average and lower rated engine there is a lot to gain, funny enough, the weaker your engine the more gain there is.

Remark regarding strength: It's reasonable to assume the ProDeo (CHT | EBF) approach will be somewhat superior to the Polyglot way of doing things as 1) they always pick the best move available from the available book moves while Polyglot picks a random move based on the "weight" value and 2) Polyglot opening books lack learning as I have understood.

Last step

conversion to Chessbase [*.CTG]

 

This is a do it yourself job. Select your favorite Chessbase | Fritz book and add the analysis work of Dann Corbit and Les Fernandez of 111 million positions to the *.CTG book.

Old Fritz interface

Edit -> Opening Book -> Import games

Click to enlarge

New Fritz interface

Analysis -> Opening Book -> Import games

Click to enlarge

The 111 million positions are split into 13 parts because Fritz has a PGN limitation of approx. 9.5 million games (positions) and thus after unzipping the download you will see 13 PGN files. The first 12 (dc.001.pgn - dc.012.pgn) contain each 9 million positions, dc.013.pgn 3.2 million.

 

Import each PGN to the loaded Fritz book (see the pictures), it will take about 15-30 minutes depending on your PC and you will notice that after each import the Fritz book has increased with approx. 1 Gb in size. This is no typo, if the job is done you will end up with an opening book of 13-14 Gb. Really...

Check it out

 

To check if the book is okay and the position are in paste the below EPD strings into Fritz and see if the position and move are available. The below 26 positions represent the first and last position of each dc.001.pgn - dc.013.pgn.

DC-PGN.7Z

Approx. 1.2 Gb

The above positions should be also visible in (and playable from) the (above) Polyglot DC.BIN opening book.

 

And now I have enough,

besides my hard disk needs a rest as well.
