Up to date opening database?

[Kirill Kryukov]

Hi all! I am using PGN Extract to classify games by ECO and opening. I found a typo in the bundled eco.pgn, so I am curious if there is any ongoing project to maintain the opening classification database. Does anyone know about it? If not, where I can find most up-to-date version of opening database? Thanks!

A modern alternative to ECO and NIC is the four digit SOC (Standard Opening Code) classification. A gzip text file suitable for inclusion into a program source can be found at:

Thanks for the link! Interesting but not what I am looking for. Sorry, I think I was not clear enough.. I am looking for any actively maintained database of opening names.

Example from my copy of eco.pgn (A01 variations):

Code: Select all

[ECO "A01"]
[Opening "Nimzovich-Larsen attack"]

1. b3 *

[ECO "A01"]
[Opening "Nimzovich-Larsen attack"]
[Variation "modern variation"]

1. b3 e5 *

[ECO "A01"]
[Opening "Nimzovich-Larsen attack"]
[Variation "Indian variation"]

1. b3 Nf6 *

[ECO "A01"]
[Opening "Nimzovich-Larsen attack"]
[Variation "classical variation"]

1. b3 d5 *

[ECO "A01"]
[Opening "Nimzovich-Larsen attack"]
[Variation "English variation"]

1. b3 c5 *

[ECO "A01"]
[Opening "Nimzovich-Larsen attack"]
[Variation "Dutch variation"]

1. b3 f5 *

[ECO "A01"]
[Opening "Nimzovich-Larsen attack"]
[Variation "Polish variation"]

1. b3 b5 *

[ECO "A01"]
[Opening "Nimzovich-Larsen attack"]
[Variation "symmetrical variation"]

1. b3 b6 *

Naturally as theory develops some new names may appear for openings or variations. I am curious if anyone is keeping an up-to-date database of such names.

Any help would be appreciated!

Best,
Kirill
