Re: Whatever is current - Amazing Leela

After that you'll have the lines that show the Italian is busted, and will be able to get book wins against opponents that play it against you. I have found no other use for those lines... You seem to be back to claiming that Black wins after 1. e4 e5 2. Nf3 Nc6 3. Bc4. Earlier you said "busted" me...

Re: Need Lc0 help

I'm still wondering about what you mean by "get it wrong" and "find the answer." After 1. a4, probably every move (except 1...b5, perhaps) likely draws with perfect play. I don't understand what you hope to determine from any number of human games that opened 1. a4. Probably every one of those game...

Re: Need Lc0 help

I assume that for each of your 18 positions, he's given you best move and evaluation (= 100 * probability of win??) from two different nets. No. For each of the moves in the list, the computer evaluation and the actual outcomes from real games disagree. When the move played by the computer is perfo...

Re: Need Lc0 help

I suspect that an analysis of the plans will show some great tactical move that has a foil. This analysis is surprisingly pivotal for me. For two decades, I have known that the top engines get it wrong a lot But it was easy to get to the right answer, just double the time and run again. Still wrong...

Re: Need Lc0 help

... Stockfish seems powerless in these positions. 2 hours with 64 cores does not help. I can tell by examination of the statistics that the SF answers are not correct. Does someone have a high end GPU setup and the time to pound these positions for a while? (BTW, these are from Ed's two move file.)...

Re: Some NUMA data for Stockfish-dev and Cfish-dev

Cfish's nps was more than 3x that of Stockfish? (Looking at "Time elapsed", maybe not.) I suppose the difference in local/remote ratio is due to Cfish making sure that the memory for each thread is allocated on the node on which the thread runs. I was so fixated on the local vs. remote DRAM access ...
