I have a new version of FabChess: https://github.com/fabianvdW/FabChess/releases

This version is about 100 elo stronger than the previous version:
Tests against Version 1.10 at 60s + 0.6s TC:
+375 = 253 -159 +97.87 +/- 25.22

Changelog:
-The readme was a disgrace to the project. It has been updated.
-I am currently writing an implementation wiki regarding FabChess. The evaluation page is already finished, so If you're interested check it out: Wiki, Evaluation Page
-Other changes were evaluation changes only, mostly:
-Pawn mobility was added
-Evaluation of Attacks was changed
-Evaluation of passers was changed
-Asymmetrys of PSQT were removed
-Some backend refactoring preparing SMP for future updates.
The endgame related issues now seem to be less, but are not completly resolved. I am still working on this.

I have also done several gauntlets against Glaurung, NoraGrace, AnMon, Hermann and Jumbo and Detroid.
For 40/4 TC, I expect the elo to be somewhere in the upper 2600's, maybe 2700. For 40/4 the Elo might be at around 2650. (CCRL scale)
As always, much love to the testers who have tested previous versions of Fabchess.

You have to look at the commits they show the update. RapChess is always just one js file.
Just clone/download the master as zip and use the new rapchess.js.

You can still get dev builds from https://ci.appveyor.com/project/christi ... no/history by clicking the desired build, selecting the configuration, and then selecting artifacts. The failed builds still seem to have executables, with a version number one version behind.
