Home * Engines * Fire

Fire [1]

Fire, (Firebird, Fire xTreme)
an UCI compliant chess engine by Norman Schmidt [2], until version 3.0 derived from IvanHoe and the Ippolit series of programs with some help of Milos Stanisavljevic. Initially called Firebird, and later renamed to Fire due to a trademark naming conflict [3], it was released as open source, Fire licensed under the GNU GPL. The sources were later closed with Windows executables available for download for recent Intel processors [4]. Fire features magic bitboards, it can be configured with more than 70 UCI options, and applies a SMP parallel search. Since April 2021 with Fire 8.1, the program is open source again [5].

Fire 4

Fire 4, released in December 2014, was a compete re-write and does not use any source code from or related to Ippolit. It supports Syzygy Bases, and includes a revamped memory management which uses OpenMP #pragmas to utilize thread local storage [6] and minimize the amount of 'shared' resources among threads for its SMP implementation. Testing was done via massive parallel, automated 24/7 ultra-fast chess engine matches using Cutechess-cli and LittleBlitzer. Code changes were tested to a very high level of confidence using LOS and SPRT (min. 40,000 games) against a pool of top engines. Development and testing included approx. 200,000 - 240,000 ultra-fast games per day [7]. According to a CCC posting by anonymous poster cucumber in September 2020, but in contradiction to Norman Schmidt's later statement [8], Fire 4 was later released as open source engine Seagull based on Gull, hiding its Fire 4 origin [9].

Fire 5, Fire 6.1

Fire 5, released in November 2016, improved with new evaluation terms, and SPSA tuned evaluation and search parameters, and supports Chess960. Fire 6.1, released in September 2017, added approximately 30-40 Elo in playing strength [10].

Fire 7.1

Fire 7.1 from May 27, 2018 [11], will be the last public release of Fire [12]. Its private successor, Fire 8_beta won the League 1 of TCEC Season 19 in summer 2020, and qualified for the top eight in the Premier Division. On September 18, 2020, Ethereal author Andrew Grant published a Fire 7.1 GPLv3 Source Request in CCC, since he believes that some or all of Fire is likely to fall under the GPLv3, as it is inherited from Stockfish's GPLv3 license [13].

Fire 8

Fire 8 with smaller and highly tuned evaluation was released on Februray 23, 2021 [14]. The further optimized Fire 8.1 was released on April 16, 2021 as open source, licensed under the GNU GPL [15].
