The legacy of Klaus-Peter Zuncke

Vaclav Kotesovec from Czech Republic made available the legacy of Klaus-Peter Zuncke. You can download Zuncke's collection of 59196 miniatures in CBV format from my or VK's website. He told me it would be Zuncke's will that it is published. The file size is 6.842.914 bytes.

VK: (didn't find the link on his website yet)
SH: [link removed due to a legal threat by Wolfgang A. Bruder] (note: original name was minis.cbv so it may uncompress with this name. Please copy it into a new folder and open it there.)

It saddens me that such fine problemists are no longer with us. Anyway, I'd love to access Herr Zuncke's collection of miniatures, but haven't got a clue what CBV format is. Can somebody please enlighten me? (What software uses it?) Thanks in advance!

CBV is used by ChessBase programs (like Fritz, Shredder, Chessbase) as an archive. When opened, it extracts several files (most probably minis.cbh etc) and destroys itself.

If you don't have access to such a program, I made available a PGN version at [link removed due to a legal threat by Wolfgang A. Bruder] - however, if you want to continue the collection it's preferrable to get a program that can open CBV.

Also, some of the problem entries are defect. I found two with only kings until now. Hopefully it's not too many.

Sorry, I had to remove the links and files since Wolfgang A Bruder threatens to undertake legal action. He says to be a co-owner of the database.

Thanks for all this Siegfried. (Some people are touchy when money is apparently involved... Pity.) Do you know if there are any free or shareware programs that read CBVs? Or only ChessBase etc.?

Actually, Google helped me to answer my own question! The **free** ChessBaseLight2007 program will apparently do the trick: see

@Administrator: Milan, should this sort of thing be discussed elsewhere (i.e. Computers and Internet area)? Sorry if I have transgressed...

Ceterum censeo PGN (and even more CBV) for problems esse unsuitendam :-)


P.S. I've heard chess problem XML standard finally is accepted?
Someone knowing please ACK/NACK this info.

It's hard to acknowledge whether you have heard it, but yes, the standard format has been provisionally accepted.

Accepted by whom? PCCC? In any case, this notion of 'standard' or 'accepted' format shouldn't invalidate the older (less flexible) formats like PGN - particularly when the newer ones don't work on older, less powerful computers (such as my Pentium III [running Windows 98]) owned by problem-lovers who simply can't afford to upgrade their computer-system. I hope you understand that I don't have anything against XML etc.; rather, I don't wish to see it 'outlaw' its ancestors!

Coincidentally, a couple of hours after writing the previous message, I received in the post the January 2008 issue of "The Problemist"; it includes the minutes of the Rhodes PCCC 2007 Congress, showing some discussion of this very matter! (Meanwhile, I'll have a look at the website mentioned therein: ) Anyway, if XML _does_ become the de-facto standard, I think that _free_ software which is compatible with older operating systems and computers will need to be made available so as not to disadvantage any of our colleagues who cannot afford to update their computer systems; this is simply a matter of justice... As I already said, I'm not against XML in particular (or technological advancement in general), but if the PCCC sometime in the future expects people to submit their work for, say, FIDE Albums with this format and ONLY this format, then it had better be freely available and backwards compatible!

I've now had a chance to look at the abovementioned website, and it allays most of my fears: there are free downloadable XML readers and writers. Also, in looking at software on my own out-of-date computer, I see that Excel (at least!) can deal with XMLs. So all seems well!!!

@Administrator: Milan, is there any possibility that you might enhance your MatPlus Librarian program so that it would read/write PGN files? It would be fantastic if you could find the time to do this...
