Installation

Download and extract zip file in specific folder. In graphical user interface choose file bbchess.exe (bbchess). Then select engine BBChess as an active engine. You can download the 5men bitbases and books from Leo Dijksman's WBEC site http://www.wbec-ridderkerk.nl . Then put them anywhere in your computer. You have to change path in the uci options (BookFile and Bitbases). The egbbdll library (dll or so) must be in the same folder as the bitbase files. For parallel search you have to set uci parameter Threads to number of procesors.
