I have just released a follow-up version of my chess engine: Fischerle_0_9_50. It is available for download at http://www.stuckardt.de/index.php/schachengine-fischerle.html
The main new features are:
- the king plays a more active role in late middlegame / early endgame;
- most instances of some important types of draw (viz., particular positions of type king vs. rook pawn or king vs. rook pawn and wrong-colored bishop) are now properly recognized;
- configuration file config.ini enables the user to alter some supplementary settings (such as the font and font sizes to be employed for displaying chess pieces in Fischerle's proprietary GUI).
Moreover, a distinction is now drawn between a 64 bit and a 32 bit version. While the code base is identical, there is just one difference: in the 32 bit version, more hash table entries are assigned since their memory footprints in 32 bit environments turned out to be slightly smaller than in 64 bit environments.
I have as well added a 32 bit version to the Fischerle_0_9_30b distribution. If you'd like to continue using this older version: it is as well available at http://www.stuckardt.de/index.php/schachengine-fischerle.html
