Re: Match between SF 10 and Fat Fritz
Interesting to me is the different evaluation of the two positions.
Why is SF so wrong? Horizon Effect?

Black has the move, so cp = -189 means WHITE is +1.89.

Re: Match between SF 10 and Fat Fritz
So, Chessbase marketing of Fat Fritz started in full. The regular Lc0 branch of T499xx nets does use 100 most popular human 4-plier openings, and if one is curious about KID specifics, main variations of it could have been added as openings. I am not sure Fat Fritz plays KID any better than 499xx nets, or even main run 42xxx nets or JH latest bignet. And overall, Fat Fritz might play worse both the openings and Chess in general than the main run late 42xxx nets. SL hardly got any spectacular result with Leela based NN engines.

Re: Match between SF 10 and Fat Fritz
The weakness of SL has more to do with the bad tools than an inherent problem with SL. I’ve developed a tool that allows me to generate V4 data using pgn’s and sf10 multipv. Head to head, the 128x10 CCRL net is 250 elo weaker than Bad Gyal 7 (where the source material is unfiltered lichess games). And mind you, the sf10 multipv is only at depth 11.Laskos wrote: ↑Mon Aug 26, 2019 6:55 pm So, Chessbase marketing of Fat Fritz started in full.

Fat Titz by Stockfish, the engine with the bodaciously big net. Remember: size matters. If you want to learn more about this engine just google for "Fat Titz".
