'''Isa''', (ISA) <ref>[http://www.talkchess.com/forum/viewtopic.php?t=61891&start=4 Re: Isa version 1.9.8 release] by [[Gabor Szots]], [[CCC]], December 10, 2016</ref><br/>
a chess engine by [[Daniel Anulliero]], written in [[C]], and compliant to the [[Chess Engine Communication Protocol]]. ISA's development started in 2014 using the [[FirstChess]] source by [[Pham Hong Nguyen]], and gradually evolved to an own engine with multiple [[Search|search]] enhancements as well as [[Evaluation|evaluation]] features implemented over the time, also documented by its author's postings in [[CCC]]. Isa was first public released in October 2016 as version 1.9.8 <ref>[http://www.talkchess.com/forum/viewtopic.php?t=61891 Isa version 1.9.8 release] by [[Daniel Anulliero]], [[CCC]], October 30, 2016</ref> with steady improvements and fixes in subsequent versions.
Since November 2018, Isa 2.0.64 is available as [[:Category:Open Source|Open Source]] under [https://en.wikipedia.org/wiki/GitHub GitHub] <ref>[https://github.com/Dany1962/Isa GitHub - Dany1962/Isa: a winboard chess engine in C]</ref>.
