Yet Another Chess Update ... YACU ... :-)
Sorry, but Yace (stands for Yet Another Chess Engine) is a good name for the
next free WinBoard Engine,
the 52nd or the 53rd compatible engine !
The night YACU was made public, Ozwald 0.42 by Jori Ostrovskij was too !
The programmer wrote in WinBoard Forum under:
1. !
2. !

Yace (program by Dieter Buerssner) detail page in German and English is ready.
Thanks Mogens Chr. Larsen for the translation !

Subjektiver Spieleindruck:
Es liegen mir nur sehr wenige Informationen zu Yace (Yet Another Chess Engine)
vor. Dieter schrieb mir, dass er vor ca. 8. Jahren mit der Schachprogrammierung
begonnen hat. Sein Programm geriet dann aber einige Jahre in Vergessenheit.
Bitte unbedingt die readme files von Dieter Buerssner lesen. Dieter Buerssner
führt dort alle Änderungen sehr schön auf.

Yace (Yet Another Chess Engine) is developing into a very strong computer chess
program. Probably somewhere between 2325-2375 ELO in strength and maybe even
higher, especially at blitz. Yace is a splendid addition to the growing number
of strong WinBoard programs that I have the pleasure of testing. The number of
features are increasing at the speed of light due to a fast, attentive and
communicative programmer. All in all it's a very recommendable program to
anyone, who likes to fiddle with chess program settings. Furthermore, if you
have any ideas about features worthy of implementation, please contact the
author, or post them at the WinBoard Forum.

Now the third Yace version, download under: (Dann Corbit`s FTP) !

time interest on chess programming !!
