'''Alfil''', (Alfil Chess, AlfilChess)<br/>
a chess program by [[Enrique Sánchez Acosta]], written in [[Cpp|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'' <ref>[http://esacosta.wordpress.com/home-2/alfil-history/ Alfil History | esacosta´s Blog]</ref>.
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|parallel search]] with multiple [[Thread|threads]] and are able to probe [[Nalimov Tablebases]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=41263 Alfil 11 MT] by [[Enrique Sánchez Acosta|esacosta]], [[CCC]], November 29, 2011</ref>,
=C# Engine Project=
The [[C sharp|C#]] Engine Project, at first dubbed '''Alfil 15''' and released as [[:Category:Open Source|open source]] in 2015, started from [[Stockfish|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.
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 <ref>[http://www.chessdom.com/alfil-leaves-tcec-stage-1b-due-to-own-book/ Alfil leaves TCEC Stage 1b due to “Own book” | Chessdom]</ref>.
After that incident, and due to discussions on Alfil's 15 origins in [[Computer Chess Forums|computer chess forums]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=57433 Re: Has Alfil 15.8 been withdrawn?] by [[Jose Maria Velasco|Jose Mº Velasco]], [[CCC]], August 29, 2015</ref>,
the author made these more explicit on September 02, 2015, and invited everyone to collaborate <ref>[https://github.com/Alfilchess/Engine/blob/master/README.md · Engine/README.md at master · Alfilchess/Engine · GitHub]</ref>:
This is a new project in C# mainly from Stockfish but intended to serve as a working tool (in Spanish) for future chess engines and tools, like Chessaria AICE.
