Re: game showing some blindness by Lc0

Lc0 finds a move when that move is the "first focus" -- your pic shows it still hasn't chosen it. It does, just a few seconds later. I was just trying to highlight the earliest when it started considering that move seriously. With TWO 2080 Tis, like what Thomas Spark over at the Chessbase Server ha...

Re: game showing some blindness by Lc0

This was a rapid game so White may not have had 30 seconds to make the right move, and would have required even more than that if running on lesser hardware. Stockfish will find Qxd3 right away. True. Rapid games are certainly not the forte of GPU-intensive Engines.Even the first AlphaZero-Stockfis...

Re: game showing some blindness by Lc0

This was played on playchess.com today. White (Lc0) seems to have made a couple serious errors here. One is 31.

Re: It's here ...Honey X6

Is it an Alpha-Beta Engine ? Only interested in Engines using the GPU not the CPU.

The bigger Nets seem to be very strong. All the more reason to upgrade to the 2080Ti, so as to take full advantage of the bigger Nets.

I do not recommend 4 threads. I recommend what ever runs best on your system. You must tune to your CPU and GPU. Remember I am running a AMD 2950x. My cores are slower then say a 9900K. So when tuning it ran slightly better with 3 or 4 threads vs 2. OK. Actually 2 Threads seems to be giving best re...

logically it should be more for a RTX2080 ti.
Yes, that would explain mwyoung recommending 4 Threads, as he has a 2080 Ti.
At the same time, going overboard with the number of Threads also seems to be a bad idea.
One should find the correct balance.
Is using an odd number of threads a bad idea ?

We have a tendency to always want to carve some ideas into stone. Without actually testing if are assumptions are correct. True. What's really surprising is that some otherwise very intelligent people also tend to have closed minds. I still remember how I was laughed at by the Big Brains here when ...

Re: Lc0 + 320x24.J13B.2-swa-136000 vs. Stockfish 250919 TC= 30m+30s

The question you need to ask is why others are not tuning Lc0 to their rig for best performance. I guess because then do not know how, or don't want to take the time. I have seen some very bad setups for Lc0. I will tell you. If you are setting Lc0 for maximum NPS. You are on the wrong path. NPS wi...
