spoiler down below.





































bm Bb6+;
ce 32760;
dm 4;
pv Bb6+ Nc7 Bbxc7+ Ke8 Bhxg6+ Nxg6 Bxg6#;

These look to be malformed.

In every other EPD file I have, I see

id "xxxxxx"

this has no quotes. Ditto for the pv...

Quotes are not needed for the id field if it does not contain spaces.
There are many test sets with that format.
