[Scidvspc-users] Scid.eco

[Gregor C. <re...@gm...>]

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." (from http://en.wikipedia.org/wiki/Zukertort_Opening).
So this seems to be more common:

    A04 "Zukertort"  1.Nf3 *
    A06 "Zukertort: Queen Pawn Defence"  1.Nf3 d5 *
    A09a "Reti"  1.Nf3 d5 2.c4 *

Cheers,
