Popular opening books

[Dann Corbit]

The EPD positions in file popbooks.epd are book exit positions from the following popular opening books:
25000_10m_hc
500_8m_fc
FEOBOS_V20_c5
hert_53
NoomenGambit
superfinal_9_10

Many of the EPD positions are extrememly polar. All positions with a centipawn evaluation with absolute value above 65 are found in popbooks-hi.epd

Many of the EPD positions are extremely drawish. All positions with a centipawn evaluation with absolute value less than 25 are found in popbooks-lo.epd

The positions with a centipawn value between 25 and 65 are found in popbooks mid.

If, for instance, you fall out of book with one of these positions:

you will exit the book with an advantage of more than one and a half pawns.

Positions with a score of zero after a deep search are very likely to be drawish. The goals of the above books are related to having more decisive games. If 37% of your book exit points are drawish, I guess that you will get lots of draws from those positions.

So the file popbooks-mi.epd has the positions in between.

How can I convert from epd into pgn?

How can I convert from epd into pgn?

You can try Ed Schroeder's EPD2DIAG utility:

http://www.rebel.nl/epd2diag.htm

Just open the EPD file, then export it to PGN.

Thanks Tony. I'll try that.

Actually, EPD2DIAG is hosted on Ed's site, but the author is Manfred Rosenboom.

I can't successfully convert Dann's epd into a pgn file suitable to be read and used.

There will be no other way. All tools which convert epd to pgn create the pgn headers and a fen tag.
It is (nearly) impossible to construct a pgn which contains all possible moves until the final epd position
due to bazillions of transpositions.

Normally all programs, which read pgn should read the one you showed above.
Are you sure ChessGUI cannot read above valid pgn example?

Doesn't seem to.
