Okay, you can find the binaries here: https://github.com/TMueller83/Stockfish/releases
(The source code does not reflect my changes yet. I will correct that later, I have to learn how to use github :oops: )

The binaries should work on devices with 64-Bit ARM processor. Notice, that I have renamed the "UCI_Sleep" option to just "Sleep" because I have noticed that some apps do not give you access to some or all options prefixed with "UCI_" because these are usually controlled by the app internally.

It would be nice if you could give me a quick feedback if the engines run on your device, since so far I have only tested them on my own phone. Until then, have fun...

Hi TobM
I tested the engine in android 9.Snapdragon 665 (2 devices)and all is right.
Thank you very much :)

Hi camava,
happy to hear that! I have just updated the binaries once more. They are now based on the newest code of Mike, are much smaller and also binaries for older Android devices having 32-Bit ARMv7 CUPs are provided.

Honey XI is now available for download.

The package includes 10 different flavors of engines, those marked with FD also have Fortress Detection code by Joe Ellis.

This included version of Bluefish includes code by Eelco de Groot and is not related to the high threaded Bluefish that shows up occasionally at broadcasted chess matches.

Hi Mike,
I found Bluefish very accurate to chose good variation. What's the trick inside ?

And is Bluefish good to play games compare to Stockfish ?

It's mostly tweaked pawn values, piece values (and their relationships) and increased king's danger awareness. Bluefish's changes could easily be implemented in any other Stockfish derivative and have the improvements pile up.

Primarily gives slightly more weight to evaluation scores than piece scores - in general piece values are 78% of normal SF. About 30 Elo weaker in speed chess type games of 2' 1". Seems to be better in positional/sacrifice test positions from what i have seen , has not translated to better against SF. The code changes are by Eelco de Groot, I agreed to keep it updated with latest SF for him.

Hi, Mike !
About the Fortress Detection version (Honey-FD-XI)
I saw this phenomenon when I tested FD with some position : Honey-FD-XI evaluates properly when there's a fortress in the positions but it doesn't find the saving move to get in these positions.
It is possible to improve this ? Or is it closed linked to the heavy pruning of SF ?

I selected 4 positions from the Hard-Talkchess-2020 set :
