Re: What is "Stockfish Level 8" on Lichess?

It shows for level 8 1000 ms, skill 20, and depth 22. So does this mean that it runs Stockfish for one second on one thread at full strength but quit if 22 ply are finished before one second? Yes, exactly. So it will run something like `go movetime 1000 depth 22`. However, since the switch from pyt...

Re: What is "Stockfish Level 8" on Lichess?

Does anyone know what version of Stockfish, how many threads, and what settings (Elo perhaps?) are used on Lichess for the top level (8) Stockfish? The level 8 is Stockfish level 20 but with some limitations. Here are the definitions of the levels in Lichess code : https://github.com/niklasf/fishne...

Re: What is "Stockfish Level 8" on Lichess?

While for analysis lichess (via fishnet) uses Stockfish 14, for play against humans it uses Fairy-Stockfish. To my knowledge this mainly has two reasons: It supports an extended range of difficulty levels in order to also have suitable engine opponents for beginners, and it supports positions that ...

Re: Gary Kasparov 58 Years old is no longer 2812 use your engine

considering these young GM's being busy with chess almost all of their time (except Anand maybe), Gary's performance to me actually looks very good. Fun to watch btw, the youtube reports from this Croatian tournament (at least some parts, which i watched, looking at all the stuff is too much for me...

Re: How perform stockfish 14 in odd match?

Quoting the description of stockfish 14: "the new network is not only larger, but more importantly, it deals better with large material imbalances". Has anyone done any tests versus other engines? What is expected of the outcome against humans? Is now a good competitor against Dragon 2 MCTS in odd ...

Re: Gary Kasparov 58 Years old is no longer 2812 use your engine

Today he scored 2 out of 9. His fide blitz rating dropped 157 Elo points to 2644. Aside from being rusty, it also shows just how much the level of chess has advanced, especially at blitz due to online play. Now i don’t feel so badly about my own fide dropping 200 points. It is another world now. So...
