a chess program developed by Eugenio Castillo Jiménez to run under MS-DOS. Eugen participated at the WMCCC 1996 in [|Jakarta], the WMCCC 1997 in [|Paris] and the WCCC 1999 in [|Paderborn]. Further, Eugen played various Spanish Computer Chess Championships, and won the SCCC 1996.

According to Eugenio, Eugen was partially inspirated by freeware programs like Turbo Chess, GNU Chess, and Crafty. It used 16 bit attacktables which were incrementally updated in every make and unmake move, the search uses iterative deepening, and recursive nullmove (R=2). Álvaro Begué, who for a short time worked with Eugenio on a computer chess project, mentioned Eugen had a good implementation of the null-move quiescence algorithm, based on the ideas and publications by Don Beal.
