Yes I sent that mail. I confirm your observation. I've uploaded a corrupted
book.bin and books.bin on my website. If someone wants to make the test too:
http://volker-pittlik.name/temp/book.bin (corrupted, 1KB),
http://volker-pittlik.name/temp/books.zip (generated from an old start.pgn,
2KB). This books only work with version 13.10.

Now I feel a bit uncomfortable. Your alleged finding was very convincing for me
because I don't believe an engine could use the book of another one by random.
As your observation isn't valid anymore I can't reproduce any of the other
findings because the public versions of Fafis don't support the setboard
command. And I'm afraid no one else can who don't has an experimental version of
the engine.

I think the author can change this situation by releasing a version with the
setboard command enabled. OTOH the source code is now inspected
(http://f27.parsimony.net/forum67828/messages/1522.htm). I hope we will have a
clear result soon.

Volker
