Up Topic The Rybka Lounge / Opening Books / e4 d4 c4 Nf3 e3 TESTSUITE for Engine Tournaments - 8 mover
- - By bformless (**) Date 2015-03-30 20:06 Edited 2015-04-01 04:18
I proudly present my TESTSUITE for the following openings:
e4, d4, c4, Nf3, e3

This Testsuite or Opening Book contains 1.050 normal, sharp, ultrasharp and very nice opening lines chess engines would play, and it's perfectly suited for chess engine tournaments.
No human games involved. It took me months to compile this nice Testsuite and i hope i have removed all doubles.

Sedat Canbaz complained a few weeks ago that he did not see really strong moves in his tournaments and now here it is! Ready for you to download this excellent 8-mover Tournament Opening Testsuite.
Go and get it now! It's only available for a short period here:

I am working now on an other project, but i will get back soon to the openings g3, a3, h3, d3, b3, c3 and Nc3

Have fun and

cul8'er.

Thanks.
I'm keen to use this without the 1.e3 lines.
Any chance you could email me the pgn without the e3 lines?

Graham.

My ESGTB says that e3 (0.07 Eval) is slightly stronger than c4 (0.04), but this could change as my analysis continues. Who knows? ;)

I think that 1.e3 is under-appreciated.
It is a good surprise opening against someone not prepared.

I've used Aquarium for sorting out all the openings over an eval of +0.22 with Stockfish, truncated the opening lines before to 8 and then ran test matches up to move 14 with 30 plies deep and truncated them again to 8 moves.  Then i ran pgn-scan to sort the doubles out. The whole process took me 2 weeks analyzing sorting and checking over 10.000 game matches (2000 for each opening) up to move 14 with 30 plies deep.

Maybe i should check them all with cutechess-cli again, because i think Aquarium has a bug with the eval  scores in Engine Matches. Sometimes it does very well and sometimes it doesn't correctly sort out the suspicous lines.
Parent - - By user923005 (****) [us] Date 2015-03-31 02:51
Most of the lines are pretty small in eval for the book termination points.
That one was a glaring exception.
I guess that there will be less than 50 with a centipawn eval over 40 when I finish analyzing the exit points.
Parent - By bformless (**) Date 2015-03-31 03:17 Edited 2015-03-31 03:20
Ok. Well. Thank you for your help. Can you sort out the worse lines and then repack the pgn? And please make the openings random then, or give it to me i will do that then, because i want to have real random openings in this pgn-file.
And thank you again. I hope this will be a really well opening book for tournament matches. ;)

SCID says 1051 openings. Aquarium says 1051. pgnscan says 1025 and no doubles (dbl, dbl -abs, dbl -exa).
Can you tell me what tool are you using?

Those tools will all say that the openings are unique even if there are transpositions.

This is leaf.c:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

char string[32767];

What do you suggest? Should i remove them? And thank you for your analysis. If you want me to remove these lines i need the exact opening line.

It is up to you what you want in your book and not in your book.
Here attached are the interior and leaf nodes with a score of at least 30 in absolute value according to computer analysis.
The time and depth of the analysis is included in the records.

Some book authors consider 30 a reasonable breakpoint, others use 40.
I think it depends on what the book is used for.

Another thing to worry about is "hard-wired" draws where a forced repetition or series of checks is found.
You might examine the pvs in the list of zero score records to see if you want to remove them.
Otherwise, you might get nothing but draws from a large portion of the openings.
