New version of the Shallow chess engine.

[Graham Banks]

Good day, Graham!
I've no time for last few years but now I've implemented new version of Shallow engine.
it is based on previous version but completely reworked
by my assumption it plays ~150..200ELO stronger
it is x64 only and supports multi-threading through standard UCI commands
It also supports Winboard but UCI is preferable as it is supported better
May you please add it for testing?
Build could be found here: http://dimock.anabar.ru/samples/shallow.7z.
it is built for Windows
Source code and some related information could be found on this small web-page: http://dimock.anabar.ru
Thank you!

Thanks for letting us know. Only problem is version number because it only displays Shallow, same as the previous one.

Just take the release date. This was always done, if no version number was available.
I added the new version as 2020-09-09 to the chronology for now.

Always? Currently there are two Shallows on the CCRL, Shallow 1.0 and Shallow 2 rev8. Now 2020-09-09? Not that I mind but looks funny.

That's exactly what I was going to call it.

I bumped on the same problem but found a "nicer" solution. If you check on the github page for Shallow, under "releases" you'll see 3 of them, and the last one, with 9-9-2020 date is called "v3.0" there. That's what I used.

Thanks! Obviously I did not look up the repo after Graham announced it. Renamed it now to Shallow2 3.0 in the chronology.
Still I feel tempted to compile it myself and stamp it ;-)
(I really don't know why authors give the source a version number, but then don't add it to the binary)

Not only that. I recall, when we discussed the name issue the author himself told us that using the date as version was fine. Or does memory fail me?

I checked the CCRL forum and indeed he said so, but may be he just did not want to make a fuzz about it, who knows...

Can we refer to the new version as Shallow 2020-09-09 64-bit?

Good day, Graham,
Yes, you could give any suitable name
Would you please add my name in "author" section on related web-page and add home-page ref: http://dimock.anabar.ru ?
Thank you!

After rechecking a lot of entries of the chronology in the last week I noticed that the (non existing) 'version numbering' for Shallow and Shallow2
is very weird in hindsight.

I have found five versions (note that none of them is compiled by me) here starting with so called Shallow 1.0 JA from 2012 (not yet checked the revision number). This one is still xboard.
Then there I have two other Shallow (uci) versions named r688JA (2013!) and r694LC (2016-09), but the github repo for Shallow (master)ends at revision 675!?!

Then I have the Shallow2 r8LC (2016-11) version and now the current one. Of course all mentioned ones call themself just 'Shallow'. A complete muddle.
