krppkr.2.nbw study
I would be interested to hear from someone who has an 'ok' krppkr.2.nbw EGT-file as well as the flawed one emanating from Chessbase as to what the differences are. Also, if anyone can shed light on how the flawed EGT-file came to be produced, that would be interesting: was this just a flawed CD-burn...

EGT-file integrity
You are right to point out that even the combination of an MD5sum-check and a datacomp run _only_ checks that the file has not been corrupted since it was generated - and that this does not check the EGT-generation itself. However MD5sum-check_plus_datacomp is sufficient to check that the file has n...

Please clarify ...
What do you mean by "error messages for these files ... damaged in WILHELM"? There are no EGT-files in WILHELM - only MD5sums. Are you saying that the cited MD5sums do not match your files. To check whether the files are damaged and/or the MD5sums erronous, run datacomp t filename, as see ...

eMule and Hyatt
I decided to make sure I had all 3-to-5-man EGTs ... ... so that I could create a Data Assurance Certificate for them with manifestly-correct MD5sum and eDonkey-'MD4' checksums followed by an 'integrity ok' message from datacomp. I used KK's home page to request whole tranches of files, started eMul...

Very odd!
Kirill's posted MD5sums against KBPKBP and KNPKNP agree with Rafael 'WILHELM' Andrist's, and he got them direct from Rob 'CRAFTY' Hyatt. Both KBPKBP and KNPKNP EGTs are (> 10) well shared, so I wonder what MD5sum-check/WILHELM/CRAFTY experiences others have had. The 'EGTs Online' homepage recommends...

Corruption on Chessbase DVD: krppkr.2.nbw.emd
Whether this has now been corrected or not, it is said that on a Chessbase DVD, the file krppkr.2.nbw.emd was found to be corrupt. All other files checked out against MD5sums held in Andrist's WILHELM. Does anyone know what the MD4 and MD5sums of this corrupt file were, and what they should be for t...

Rafael Andrist's input on MD5sums
Rafael Andrist sent me his file of Nalimov DTM EGT MD5sum data. This, or similar, is probably what he sent to Kirill before. Not surprisingly, it agreed 100% with what I had from Kirill earlier, although MD5sums for some 6 4-2p EGTs were not included in it: kbbbkp, kbbnkp, knnnkp, knnpkq, kqbpkr and...

Check on MD5sum file signatures - aok so far
I have cross-checked 'my' files of MD5sum file-signatures ... ... received via Rob Hyatt's ftp site from Eugene Nalimov with the files of MD5sum file-signatures made available on KK's site. All MD5sum file-signatures agree for these files: all 3-, 4- and 5-man, and 6-man pawnless (i.e., 3-3 and 4-2)...

Data Assurance Protocol: MD5sum data
I have all the MD5sum data for Eugene Nalimov's 3-to-5-man and 6-man pawnless EGTs. Provenance: I think it came direct from Eugene via Rob Hyatt's site. Action_1: I have asked Rob if he can make the MD5sum data he has available on his ftp site. I have also asked Rafael Andrist, who I presume has mad...

Uploading - the last Nalimov DTM EGTs
It is clear that none of Eiko Bleicher, John Tamplin or myself has any upload capability worth talking about, so we will not be able to contribute directly to this file-sharing project. However, if and when I get the last Nalimov DTM EGTs on DVD via John Tamplin, I will be happy to share these with ...

6-man and 7-man EGTs
The last 16 Nalimov 3-3p EGTs are only with Nalimov. The current plan is for Eugene to send a disc to John Tamplin who will DVD them for me and Eiko Bleicher. Eiko B has all available 6-man EGTs: he may or may not be able to be a sharer for your project. The creation of WDL EGTs is a helpful step in...

EGT file integrity
A suggested assurance-protocol for this project might be that: 1) Sharers indicate whether or not their file has been MD5sum-checked just before being shared 2) Downloaders (obviously) check whether the downloaded file MD5sum-checks. I've certainly had a file fail this MD5sum-check after downloading...

7-man EGT production status
Yakov Konoval is developing a code and, with the participation of Marc Bourzutschky, generating 7-man EGTs at new levels of performance. The EGTs are to the DTZ metric (i.e. to P-push, force-change and/or mate) rather than to DTM(ate) as this is more efficient in time and storage. The maxDTZ record ...
