13.2.01 Update: A couple of fixes, corrected the bench error so one could run "bench 16 1 500 true default default movetime" without getting a nnue network load error. This bench options allows the user to run the bench so that each position is give equal time (as opposed to equal depth, a truer picture of the average nps. The new option "tactical depth" was not working correctly, now fixed. Also, I had noticed the Harmon Chess app source was not fully updated, it is now.


Based on Droidfish by Peter Österlund, the Harmon Chess app is a feature-rich graphical chess user interface, combined with 27 high quality open-source chess engines.
The engine Honey engine was updated, and the true Stockfish engine was added to the Harmon Chess app, both which were updated to take advantage of the new and larger Stockfish NNUE network. In addition, the Honey engine was updated with enhanced human play options - play by node count, play by search depth, play a new and an enhanced variety mode. Honey was totally rebased on the latest SF code. Thanks to the new network, it plays 300 Elo stronger at depth one and the new network greatly increases the quality of variety play as well.

Again deep appreciation and gratitude to the Stockfish Authors, as this would not be possible without them and all of the hard work they do!

Many thanks to Peter Österlund for his Droidfish app. Link to Harmon Chess App source.
This version also includes additional piece sets by the renowned Bryan Whitby a graphical chess piece artist hobbyist.

The Honey and Stockfish engines for this version were designed to be used with this NNUE Net
The free Fat Fritz net is available here

The other Honey engines were designed to be used with this net.

Due to recent changes with the Google Play Store, you may have to turn off Play Store security function under Settings to install if it will not install normally (also you may consider turning developer mode on your Android device). The Harmon chess app must be loaded through the APK method.

Note - the Harmon Chess App **no **longer contains any NNUE nets, they must be copied to the Droidfish/nnue/ folder on your Android device.
There are several net authors who have made compatible NNUE nets available on their websites.

This version of Honey does include some code from Bluefish and will do very well on position tests - no special settings required (use default settings)

Have fun!
