a [[Stockfish#ports|port]] of Stockfish in [[x86-64]] [[Assembly|assembly]] by [[Mohammed Li]], optional using [[AVX2]] and [[BMI2]] instructions, assembled with [https://en.wikipedia.org/wiki/FASM FASM] to run under [[Windows]] or [[Unix|UNIX]]/[[Linux]], first released in June 2016. The fun project is about to demonstrate how an experienced assembly programmer can optimize a program compared with [https://en.wikipedia.org/wiki/GNU_Compiler_Collection GCC] <ref>[https://groups.google.com/d/msg/fishcooking/HKIYwO6pF-s/p9t48jDZBAAJ Re: <nowiki>[for fun] </nowiki> rewrite of stockfish into asm and question on source] by [[Mohammed Li]], [[Computer Chess Forums|FishCooking]], April 18, 2016</ref>.
