Re: The new NNUE-net (nn-308..) seems being weaker

Widely believed misconcept is that Elo-gainer (new stronger version of something) can only increase number won/drawn cases, while retaining all win/draw cases which previous version could handle. In reality Elo-gainer STATISTICALLY increase number of winning games DESPITE of getting worse in some ga...

Re: New version of Leela

v0.26.2 = v0.26.2-rc1 * Repetitions in the search tree are marked as draws, to explore more promising lines. Enabled by default (except in selfplay mode) use --two-fold-draws=false to disable. * Syzygy tablebase files can now be used in selfplay. Still need to add adjudication support before we can ...

Re: The most stupid idea by the Stockfish Team

Don't care if it is not in ABROK.
Embedded *.nnue is OK for official (yearly) build of SF-12, but not for daily DEV builds

Re: "New" Engines (lc0, MCTS, SFNNUE) and suitable GUIs

May be a dumb question.
Are there any technology which can potentially benefit from combining CPU + GPU horse power?

something like NNUE can load GPU? (not now in current version, but can it potentially be ported to run both on CPU + GPU?)

Polhl's SF testing page shows that a good book ( Brainfish's book called Cerebellum ) is worth about 35 Elo or so.

Re: Polish users cut off from TalkChess

If it would be my decision, and I am one of the founders who founded the forum in 1997, I would evacuate the whole forum to a host that is not blocking IP addresses. USA is no country anymore that guarantees freedom. If you see HTTP message 403 Forbidden - it is guaranteed that host is not blocking...

Re: Polish users cut off from TalkChess

403 Forbidden is web-server/web-script HTTP error

If you see this error - it is guaranteed that no firewall block route from your IP to this webserver IP.

It is pure HTTP error, not related to TCP/IP policies.
