Hi Gregor, thanks for the info. I've very dumb about the eco codes. For example, the A26 code in the link you posted: every game that starts with "1. c4 e5 2. Nc3 Nc6 3. g3 g61. c4 e5 2. Nc3 Nc6 3. g3 g6" is ECO A26? And if so, what is the meaning of the second line "4. Bg2 Bg7 5.d3"?
About the A00 - A06 code: how transpositions are managed? To classify a game it's used the longest matching line, or it's required to build the final positions of ECO lines and check if the game reached that position? I would like to have consistent ECO classification between scid and scidb (and possibily with other chess open source software too): could you write an email to chess informant asking for clarifications? Thanks, Fulvio P.S. I take this opportunity to wish a Happy Easter to all >----Messaggio originale---- >Da: rema...@gmx.net >Data: 18/04/2014 13.50 >A: <scid-users@lists.sourceforge.net>, <scidvspc-us...@lists.sourceforge.net> >Ogg: [Scidvspc-users] Scid.eco > >I think that scid.eco may contain the following problems: > > A00m "Van Geet: 1...d5 2.Nf3" 1.Nc3 d5 2.Nf3 * > >Due to ECO this is: A06 "Reti: Reversed Mexican Defence" 1.Nf3 d5 2.Nc3 >but in fact this isn't really clear, the ECO definitions are quite sloppy. >ChessBase assigns A00, but Scidb assigns A06. > > A25 "English: Closed, 5.d3" > 1.c4 e5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 * > A25 "English: Closed, 5.d3 Nge7" > 1.c4 e5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 Nge7 * > >This is A26, although many sources are assigning A25, but have a look at >the reference http://www.chessinformant.rs/content/eco/eco_a/eco_a2.html, >and even ChessBase agrees with A26 (is it possible that the ECO code has >changed sometimes?) > > A04 "Reti" 1.Nf3 * > >Due to most sources this is the Zukertort Opening. >"Sometimes the term Réti Opening is used to describe the opening move >1.Nf3, although most sources define the Réti more narrowly as the sequence >1.Nf3 d5 2.c4."
