**BootChess**,
one of the smallests computer implementations of a none FIDE compliant chess variant written by [[Olivier Poudade]] in [[x86]] [[Assembly]], released in January 2015. Its size of 487 (468) <ref>468 bytes without rank/file indicators of the board display</ref> bytes fits into a 512 byte [[http://en.wikipedia.org/wiki/Boot_sector|boot sector]] for [[Windows]], [[Linux]], [[Mac OS|OS X]], [[MS-DOS|DOS]] and [[Unix|BSD]] <ref>[[http://www.pouet.net/prod.php?which=64962|BootChess by Red Sector Inc. :: pouët.net]]</ref>. [[Castling]], [[Promotions#MinorPromotion|minor promotions]] and [[En passant|en passant]] are not implemented. BootChess otherwise performs a so called "TaxiMax" heuristic, maximizing [[Captures|captures]] and trying to minimize the [[Manhattan-Distance|Manhattan distance]]  to the opponent's king rank. This kind of half-ply search cannot prevent moving it's own [[King|king]] in [[Check|check]], opposed to the old [[1K ZX Chess]] by [[David Horne]] and the recent [[Toledo|Toledo Atomchess]] by [[Óscar Toledo Gutiérrez]], who took the BootChess challenge with 481 bytes and a 3-ply search <ref>[[http://www.talkchess.com/forum/viewtopic.php?t=55125&start=9|Re: BootChess (minimal chess engine)]] by [[Óscar Toledo Gutiérrez]], [[CCC]], January 31, 2015</ref>..
