Consider this position: 8/1pN4r/5pkp/8/5K1p/2P4N/P3Bn2/8 w It's one of hardest position to solve, not so easy even for multipv and at the same time it has one, clear solution! This is kind of position when u ll make correct move manually and engine quickly sees what is goiong on, but without it - i...

Now let's talk about position you described - 1rb1qrk1/2b2pp1/p3pBn1/3pP1Pp/1ppP4/2P1QN2/PP3P1P/R2BR1K1 w - - 0 21 Indeed it seems to be hard one for Sf. I downloaded Cfish 23.09.20 bmi2 version and included default net 03744 to see how Pure NNue option works for this position. I used as usually on...

Are they some tests with better results for only nnue approach? Im asking because I wasn't interested in this topic before, just thought that hybrid approach is more natural. Thanks for the detailed explanations, Majkel. As for NNUE pure or hybrid, my problem with this is mainly, that only classica...

* TacticalNodes - every one point is equal to 100 000 nodes (so for example default 1 means 0,1kk nodes). * TacticalLevel - used for decreasing tactic blindness resulting from material values. 7 means 70% of pieces values, after time specified by TacticalNodes, sf regains worth of material again. G...

Igel 2.8.0 compiles for ivybridge and westmere are provided via PMs to Rebel and peter. As written in PM, it works well, bench is ok. Igel by default gives ./eval/nn.bin as path in UCI- option, to change it in .eng- file without that, adds ./eval/ automatically at engine- start in GUI to UCI- optio...

Then just use the regular popcnt version. The NN is minimal. SSE won't do much. This one works well. About 3/4 the n/s of Ethereal 12.50 popcnt, which is quite good compared to other NNUE- binaries I know for my CPU. Crashes in Fritz- GUI when number of MultiPV- lines is changed, ("error in the eng...

Pity it doesn't Andrew. Westmere's the nearest to my Xeon, I think. Does a certain nnue- net have to be in installation folder? This is not an NNUE; it has nothing to do with SF or Leela or A0. Its just an NN thats hard coded into the evaluation for Pawns. There is no setup -- it will work as is. I...

Awesome , Windows with with above plus -mavx2 please. Thanks! https://drive.google.com/file/d/1fQ5sSQUrNhpNv9OkLk1C2GzUPJJrg8jW/view?usp=sharing I'm assuming you have a Ryzen? If not, it should still work I imagine. Pity not for Xeon X5670. :( regards Its not clear to me what target would be chosen...

Will provide you a gcc compile for your CPU by the EOD.

That's very kind of you, Volodymyr
