Verify integrity of Syzygy TB with MD5

[Patishi]

Hi,
I downloaded the (6 piece) tablebases and I want to check their integrity using the supplied MD5 file. What is the best way or program to do this?
Thx.

This works well for me.

https://github.com/gurnec/HashCheck/releases/tag/v2.4.0 looks pretty good, and is supposedly open source.

Thx man. After posting my question I also found this software and it simple and efficient
All the files passed successfully.

You may try BanksiaGUI. It doesn't require external MD5 data but uses the checksum numbers integrated/embedded already into Syzygy files. It can also tell you which files are missing/error too:



I guess my way maybe not the best but the easiest

If you're running Windows 10, the easy way (no need to download anything) is doing it in PowerShell:

Code: Select all

Get-FileHash <filepath> -Algorithm MD5

Get-FileHash <filepath> -Algorithm MD5

I saw this as well, but I wasn't sure what I should type inside "filepath". I don't want to check all the files individualy (one by one), how can I test multiple files at the same time? And also, does this method compares the two hash (md5) files? Hope I am understood (my english is not the best)

This will work for multiple files too, using wildcards, so e.g.

Code: Select all

Get-FileHash D:\syzygy\* -Algorithm MD5

...will calculate MD5 hashes for all files in D:\syzygy\ folder. It is simple, but the downside is that one gets the hashes and that's it, the comparison needs to be done by hand.

That verification tool is very neat innovation to the gui

By the way i wish there can be two syzygy paths. One for engines to consult during games and one solely for adjudication.

- engine path suited for SSD and M.2, where WDL is to be stored

- adjudication path suited for HDD storage for simple static adjudication

i tested integrity of my syzygy and apparently many of them did not pass.

I downloaded most of my tables from "sesse tablebase"

I downloaded from here:
https://chess.massimilianogoi.com/download/tablebases/

All passed successfully.

By the way, a side question.. I am using Fritz17 with Komodo (now called "Dragon") and I only use the TB with the engine.
Fritz17 software also give option to set TB to be used with the GUI, do you guys recommend using this option? As I understand, when reaching positions with 6 pieces or less (on the actual board), the GUI plays right away without the engine analyzing at all..

Can anybody comment on that?
Thx.
