Re: Shadow Walker 4CPU

Interesting that the leader is jumping around like mad, but Arasan remains nailed to spot number 2.

TCEC 14 - what happened to the final?

I was watching a while back and a lot of v14 finals games were played.
Now, TCEC seems to have moved on to TCEC Cup 2 but there are no games stored for download for the TCEC 14 finals.
What happened?

Re: A new Unbreakable from Neghina...

Well, Cfish-dev also finds Na5, albeit with a score of 0.00. But I doubt it can solve the study. Sting's PV seems odd to me. Qh6? Well, the study is called "The Confusion" It seems to toss the queen, but subsequent exchanges make most of it back. No idea why it was chosen, but it thought for an age...

Re: AMD's New RX Radeon VII - NVIDIA RTX 2080 Killer?

So i think it is AMDs turn to release some optimized OpenCL NN libraries and add TensorCores, or a similar technique, to their gpus. -- Srdja Here is a NN lib for OpenCL: https://github.com/hughperkins/DeepCL I've no idea how good it is.

Re: A new Unbreakable from Neghina...

The Romanian software developer Mihai Neghina is a specialist for super difficult chess studies... His latest composition is called "The Confusion" and is again extremely complex, even for the best engines. Probably most programs don't have a chance to get this position in less than 60 seconds... W...

Re: AMD's New RX Radeon VII - NVIDIA RTX 2080 Killer?

Does it have A.I. hardware? If not then it's not a 2080 killer as far as chess is concerned. Afaik, AMD still has no TensorCores on board, but it remains open how the price per Knps for LC0 will be... -- Srdja I think the LC0 code is strictly written for Nvidia cards, so a complete rewrite would be...

Re: CPU clock speed or core count ?

It also depends on what you are doing with the engines. For instance, when I use my 64 core machine to analyze, I usually do not use 60+ cores on a single position at a time. Instead, I break the file to be analyzed into a collection of sub-files and then divide the thread count appropriately. So, s...

Re: program to generare epd file of tactical exercises from pgn

Here is an example that is easy for computers but not for weak humans(the woman with white solved it correctly). 2b2rk1/1p4b1/3p3p/3Pnpq1/1P1Np3/1Q2P1P1/3N1nB1/B1R3K1 w - - 0 23 find the best move for white. Is there a best move if all move choices lose? I think the game is already lost at that poi...
