There is something wrong with Honey Elo Expert setting

[scchess]

Didn't Stockfish already provide well defined strength level support? What's difference between Honey to it?

Stockfish is the ultimate machine versus machine chess weapon, honey is for the club player who want to actually wants to play chess that is playing fullstrength, but only limited in strength by how deep it searches - with a myraid of choices , you best bet is to check it out and I wil be happy to help with you with questions you may have...

play by nodes count,( at one point it was tuned to CCRL, teh it was tuned to FIDE, but some levels were still too strong , so now the levesl are probably weaker than advertised, but on the othe rhand it can much much weak than stockfish, which is limited to about 1350 CCRL . Honey can play less than a 1000 FIDE - beginners (children, 6 years old ) can play a game and not lose.. I have grandchideren and that was and is important for me...
play by search depth
play by elo
adaptive play ( will keep you in the game longer no matter what level you play (reduces Elo by 300 to 400 Elo)
variety play
play with sleep mode ( example, honey will play instantly withplay by low search depth - tha can be annot=ying , activation sleep will cause honey to sleep for few seconds before replying)
up to 4 polyglot opening books can be used
tactical mode ( wider search useful in human play so honey will play smarter when playing at low depth or lwo nodes.
tactical depth - you can limit tactical mode to certain depth ( idea from SF shashin fork)
play by level ( GM, IM Expert ect)
pure nnue mode
since the weaker levels are governed by reducing depth/nodes, the battery life on portable device is greatly extended when compared to using stockfish on portable device in weakened play mode - that matters to me and many of my users using the Harmon chess app ( based on droidfish)
it's not perfect, but it works for me and it may work for you, ymmv...
and Harmon may be the only chess app where you can play with chess pieces that were designed almost a thousand years ago ...

Thanks for the great explanation. I'm suffering from an issue that the unmodified Stockfish is performing very badly at weak levels. As an 1900 rated player, I've found myself fighting very seriously against the weaker UCI level I could set in Stockfish. Either the ELO levels are tuned very badly or it would only work on the classical evaluations (I was running NNUE). I'll take a look at your modifications in Honey, and may bring them out to wider audience. Your works could benefit many SF users not browsing this forum.
