Re: For a change: easy positions for SF, but difficult to SF NN

r3r1k1/p3bppp/q1b2n2/5Q2/1p1B4/1BNR4/PPP3PP/2K2R2 w - - 0 1 From Arasan suite. SF NN has almost always +5 evaluation, but not intended move!? Is this what you mean? I guess Stockfish+nnue simply "knows" that Nd5 very strong, and so it takes longer to find something with an even higher evaluation? i...

Once the engine match in underway there is no view tab.
The view tab is in normal mode (I have clock window checked already).
Make sure you are up-to-date in patches, and if so, try Restoring to Defaults.

Re: The next revolution in computer chess?

Yes, else ply 0 Leela would beat GMs at non-blitz and GMs/IMs can mostly express in language why so and so move and so on. I would agree on this point: I want chess solved before I die. If nobody else will do it then I will. The results are very impressive, but it comes at a price: the NN, and henc...

Re: Lizard-NNUE Experiment NOT bad with NNUE Net Evaluation.........

I generated training data with Komodo 14 (and a modest amount of python). I used a recent nnue binary to train a net using that data and am running that net using that binary (as are my helpful friends). So this is an approximation of the Komodo 14 eval at depth 8 running on a sf-nnue binary. The n...

I’ve heard rumors that CB got the tuning wrong. Hopefully an update is coming soon.
For the OpenCL build yes, but the CUDA is as tuned. Otherwise anyone can enter the new tuned values manually.

Re: Fat Fritz update

The latest update is Fat Fritz 1.1 with changes to Cpuct, Fpu, Policy temp, NN cache and couple of others. Tests are required to see where it stands. Question is whether Kiudee settings work with Fat Fritz 🤔 Better than that: I ran Kiudee's tuner for 7 straight days on it to find its own 'Kiudee' s...

Re: Can Leela CPU train from a PGN file instead of selfplay?

A small number of games will create a net that doesn’t play well, but illegal moves aren’t in the picture. As I have read for recent versions Lc0 has installed some chess knowledge, including move rules (thus it is not completely Zero) to speed up learning and it can avoid the above issue. Not rece...
