ECO Code diagrams, A00-E99

does anyone have a pgn file of eco code diagrams of  A00-E99? it would be nice to get a hand on them.

Thanks.

Can you explain more precisely what you mean by a 'diagram' in relation to ECO codes?

This is the A01 diagram:

(I guess, strictly speaking, it is the transition from A00 to A01.)

Oh, now I understand, thanks.

that is exactly what I need. A00 to E99 all in a pgn file. I wanted to memorize each and every ECO code with their corresponding position. this is why I wanted a pgn file with each position. anyone have their hands on this??

if anyone ever happens to put together a pgn file with this share it here. it would be useful for us trying to memorize these. thanks!!.

It is hard for me to imagine why an FM would want to do this. Anyway, it isn't really possible. An ECO code is not necessarily defined by a single position. For example, B23 is for 1 e4 c5 2 Nc3 lines where Black does not play 2...Nc6 and also 1 e4 c5 2 Nc3 Nc6 lines where White does not play 3 g3. What single diagram would communicate that?

The only way I can see that you could do this in any semi-practical manner would be to steal the ECO codes used in the Scid vs. PC GUI. In the "data" folder of this program, there is a text file named "scid.eco". If you know what you're doing, you can use the command-line utility named "eco2epd.exe" (located in the bin folder) to convert the scid.eco file to an ECO epd file. Then you can simply open the epd file in Scid vs. PC to look at all of the ECO diagrams.

(Note that Scid vs. PC uses ECO code extensions of a through z to handle the many variations for each ECO number.)

If you want to try it out, I uploaded the epd file to Sendspace. Just put the link in your browser and click on the blue download link. The file will be available for at least 30 days.
