I've released a new version of Seer here: https://github.com/connormcmonigle/seer ... tag/v2.2.0
Thanks Connor for this new version. I started to test it today, but I see already that the evaluation seems more mature. I wishes you all the best with the development of your interesting, and original engine.

GreKo 2021.08:
http://greko.su/greko-2021.08.zip

In single-thread mode it is equivalent to 2021.06.
Most changes are in SMP stability, UCI output (including MultiPV) and code design.
Max.number of threads increased to 16.

Vladimir, I tried to test Greko several times but if doesn't run well using cute-chess -concurrency

Any idea?
90% of coding is debugging, the other 10% is writing bugs.

- Chess960 / FRC
- MultiPV and `go searchmoves`
- Online Syzygy probing for perfect play with 7 or fewer pieces (off by default)
- Improved history heuristics
- Improved evaluation of passed pawns

Here is GreKo's section from my engines.json.
Works with cutechess-cli 0.5.1 under Windows without problems.

Code: Select all

   {
      "command" : "GreKo-Windows-64.exe -t 4",
      "name" : "GreKo 2021.08 4-CPU",
      "protocol" : "uci",
      "workingDirectory" : "C:\\VRM\\CHESS\\GREKO\\versions\\2021.08"
   },
