Hmmm can you try this one below?
This is done with a little macro and yace epdtest utility which also creates valid pgn.
I noticed though that it does not produce the 'Setup' tag and still I could load it in all GUIs
I tested e.g. LucasChess, WB, etc.
(note that it is created from the popbooksmi-epd mentioned above)

You can see that even the pgn generator from talkchess can read it
(I added the first three games from the pgn)
This means if ChessGUI cannot read it this time I am running out of ideas.

ChessGUI still can't produce a cgb book from this file.
Ferdy's explanation of how to use the epd2pgn tool in ChessGUI seems to be working, but it is going to take many hours before I report success.

After 7 hours, the conversion is 10% complete.

How can I convert from epd into pgn?

PGN file is attached. It has the suggested moves included so that the game elements look like this:

[Event "?"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "?"]
[Black "?"]
[Result "*"]
[Setup "1"]
[FEN "r1q2rk1/pp2p1bp/3ppnp1/4n3/4P1P1/2N1BP2/PPPQB2P/2KR3R w - - 0 1"]

The attached file has the games without any suggested moves, so the above would look like this:

[Event "?"]
[Site "?"]
[Date "????.??.??"]
[Round "?"]
[White "?"]
[Black "?"]
[Result "*"]
[Setup "1"]
[FEN "r1q2rk1/pp2p1bp/3ppnp1/4n3/4P1P1/2N1BP2/PPPQB2P/2KR3R w - - 0 1"]

Thanks Dann. Much appreciated.
Sadly still no good for ChessGUI.

Meanwhile, after 18 hours, the epd2pgn conversion is at 31%.
Once finished, I'll report back and if successful, post the pgn file produced.

Meanwhile, after 18 hours, the epd2pgn conversion is at 31%.

That's a lot of work. I have a console program that can do the job in ten minutes.
It works like this:

Code: Select all

epd2pgn -p Twic.pgn -e popbooks.epd -d 40

It failed to translate 1100 epd lines (from the 2834) though. I suppose Twic.pgn doesn't contain all the positions from popbooks.epd.
I'm a bit late here, but if you're interested, I'll put this program on my website during the weekend.

Thanks for the kind offer Werner.
The conversion is almost 70% complete now, so I may as well see it through and see what happens first.

Cheers,
Graham.

Worst of all, about half of the terminal positions in popbooks.pgn are not good for contests (IMO) which is why I originally wrote the post.

Hi Dann,

I'm combining the Mi and Lo for a start.
I can always switch to the Lo on its own if need be.

If you switch to Lo on its own, I guess that you will get a huge percentage of draws.
I think the old fashioned goal of forming books from drawn games is a mistake.

I do not think that it measures accurately the difference in strength.
When given a giant pile of drawish positions, you end up with a giant pile of new draws.
