The current version of Velvet is now 3.1.3. I did not get any antivirus warning from Defender with this version, although I am sure that warning for version 3.1.1 was a false alarm.

Your browser may be blocking the download, not the antivirus. I tried downloading with Edge, and I had to manually select the option to keep the file because the Velvet executable is new and not commonly downloaded.

It's working now !

Protej 0.6.2

http://protej.info

Various code optimizations. MoveOverhead UCI option added, to play extra-fast ultrabullet games avoiding time losses in very slow systems. History pruning and LMR integrated and tuned. Some material imbalances are now recognized; starting point, probably it should be extended to see an improvement. Debug: due to a wrong hash variable, pawn hash wasn't used. SEE values tuned. Penalty for a bishop of the same color as its side's blocked pawns; despite the correct idea the code has to be improved. Single reply is now searched for a very limited time; there's a positive impact on short time control games. If search finds a mate in 2 moves then it stops immediately. Online Syzygy tables probed at root position; relevant UCI options added. Debug: trying to play a move when no moves are possible caused a crash; UCI commands are now case insensitive.

Zangdar 0.33

Hi,

My little program progresses. I added a Null Move, corrected several bugs.
Here it is : https://github.com/Carbecq/Zangdar

The source is not available. I have yet to clean it; and at this stage, there is nothing innovative.

Thanks

Nothing new Frank-
I simply split off a new repository to separate the releases...
one is Fire-NN
one is Fire (no NNUE)
there have been no changes.
