New release of FabChess, Version 1.10. https://github.com/fabianvdW/FabChess/r ... tag/v.1.10



This version is about 100 elo stronger than Version 1.9 in selftests at TC 60s +0.6s.

Changelog:
Tweak of history scores
History based Pruning (with another history score)
Better endgame evaluation and mate search
Aspiration window tweaks
Mate distance pruning
LMR tweaks
Slight eval tweaks for supported pawns
QOL:
Fixed about 500 Linter warnings

I am also aware that FabChess blunders every other endgame. I sadly do not know the cause because everytime a clean search does not blunder on the exact moves. Hopefully in future updates with EGTB the problem will be more insignificant (although this will not fix the root of the problem).

It may be easier to find the reason before implementing EGTB's.

I will start my journey finding the "potential" bug, but I can not foresee it will be a succesful one

Defenchess 2.2
https://github.com/cetincan0/Defenchess/releases

This release increases the playing strength of Defenchess significantly. Below are every change introduced in this version.
Changes:
Revised time management for X/Y and X+0 (moves per time and zero increment) time controls
Opposite colored bishops endgame knowledge
Slight improvements in how time is counted and PVs are printed while failing high/low (now at least one move will always be printed even when failing)
Improved thread management (fixed a bug where not providing a position after setting the number of threads would crash the engine)
Improved draw (and lack thereof) detection
Fixed an issue where TB scores would never be returned
Fixed a bug in calculating pinned piece mobility
Allowed pinned pieces to capture pieces of equal or higher value in mobility calculation
Implemented followup history
Fixed a bug that prevented extensions from being applied in the first moves searched in PV nodes
Introduced king threats against pieces and pieces flanking the king in evaluation
Introduced the use of history in late move reductions
Tweaked endgame scores for the side with higher material but no pawns
