AlfilChess, (Alfil Chess, Alfil)
a chess program by Enrique Sánchez Acosta, written in C++, first incorporated as chess engine of TotalChess 2000, and subsequently since 2001 commercially released as Alfil Chess I and Alfil Chess 2.2 by Hollywood Publishing [1]. Alfil has become a free engine under Windows, compliant with UCI, and under Linux, compliant with the Chess Engine Communication Protocol. More recent versions have a parallel search with multiple threads and are able to probe Nalimov Tablebases [2], and were ported to Android [3].

C# Engine Project

The C# Engine Project, at first dubbed Alfil 15 and released as open source in 2015, started from Stockfish v5 and various C# ports such as Portfish, and over the time incorporated ideas and knowledge gained from over 10 years of Alfil development, and from other open source engines [5]. Alfil 15 was registered for TCEC Season 8, when it was disqualified after its first game versus Pedone, since it could not disable its internal book, not complying with the TCEC rules [6]. After that incident, and due to discussions on Alfil's 15 origins in computer chess forums [7], the author made these more explicit on September 02, 2015, renamed the program, and invited everyone to collaborate [8].
