Fire, (Firebird, Fire xTreme) an UCI compliant chess engine by Norman Schmidt, 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, 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. Fire features magic bitboards, it can be configured with more than 70 UCI options, and applies a SMP parallel search.

=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 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.

=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.
