XXV has several search improvements and static eval bugfixes. Special thanks go to Fabrice Lecouvey, who studied the static evaluation and caught and reported several well-hidden bugs.

Both source code package and Win32 build is now available in the Files section.

The old Phalanx computer accounts on freechess.org (FICS) have been resurrected.

Account rusalka plays on a very easy level (-e 80) and the blitz rating is around 1000. http://www.ficsgames.org/cgi-bin/search.cgi?player=rusalka&action=Finger

Account pikozrout was originally a full strength one, but now I've decided to limit the nodes per seconds to 10000, so that it's strong enough, but still can be beaten by humans in blitz. Also see http://www.ficsgames.org/cgi-bin/search.cgi?player=pikozrout&action=Finger

The new version played 272 games against various opponents and the 40/40 rating is 2540 (+179 points to the current rating of version XXIII)

Here is a few weeks old article published on the chess.com forums by a chess.com user nicknamed EscherehcsE. The article discusses the new easy levels as introduced in Phalanx XXIII and even suggests creating stronger non-blundering easy levels using combinations of values of the new commandline options -z (randomization) and -n (nodes per second limit).

Jim Ablett graciously made a windows version of Phalanx-XXII. The package contains both a Windows executable and the modified sources to be build with MS Visual C++.

He also reports that his version is competing in Olivier Deville's Chesswar on Category C: http://loirechecs.chez-alice.fr/chesswar

If you use Windows, go grab your copy of Phalanx now: http://www.sourceforge.net/projects/phalanx

Of course, the old Unix only release is still available. I haven't yet tested Jim Ablett's build on Linux or BSD, stay tuned for that.
