'''Komodo''',<br/>
a chess engine by primary author [[Don Dailey]] (died at the age of 57 on November 22, 2013) and since October 2013, by [[Mark Lefler]], supported by chess advisor and evaluation expert and Don's long time collaborator [[Larry Kaufman]]. Since 2015, [[:Category:Opening Book Author|opening book expert]] [[Erdogan Günes]] is responsible for Komodo's [[Opening Book|book moves]].
At the [[WCCC 2016]] [[#10|Komodo 10.x]] first time won the [[Shannon Trophy]], defended by subsequent versions at the [[WCCC 2017]], [[WCCC 2018]] and [[WCCC 20182019]] so far. In November 2020, the [[Dragon by Komodo Chess]] was released, featuring [[NNUE]] technology.
Komodo appeared in January 2010 derived from Don's former engine [[Doch]]. It uses [[Bitboards|bitboards]] as internal board representation, and has a sophisticated [[Search|search]] and a knowledge based, balanced [[Evaluation|evaluation]].
Komodo '''14''', released in May 2020 with following improvements announced by [[Larry Kaufman]] <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=73916 Komodo 14 released] by [[Larry Kaufman]], [[CCC]], May 12, 2020</ref>:
The improvements cover a wide range of issues, including [[Extensions|extensions]], [[Null Move Pruning|null move]], [[King Safety]], [[Time Management|time management]], and many more. There is one new feature added since Komodo 13.3, "[https://en.wikipedia.org/wiki/Fast_chess#Armageddon Armageddon]" mode, which tells Komodo that White (or Black) must win, draws are scored as losses for that color. When draws are counted as losses for White, knowing this improves Komodo's performance as White by about 30 elo according to our tests. In Armageddon mode, the specified color (usually White) not only avoids clear draws, but adjusts [[Contempt Factor|Contempt]] by an amount we determined was most helpful for Armageddon play. Testing on one thread in Armageddon mode suggests that on a modern laptop, if White gets one minute total plus 1% increment, and Black gets half a minute plus 1% increment plus draw odds, then chances are fairly close to balanced. Other features added since Komodo 13 include more levels, Personalities, and Auto-Skill. Standard mode remains the strongest when [[Principal Variation#MultiPV|Multi-PV]] is not in use, while [[Monte-Carlo Tree Search|MCTS]] mode is generally strongest when both are using Multi-PV.

Along with the release of Komodo '''14.1''' on November 02, 2020, [[Larry Kaufman]] announced '''Dragon''', featuring [[NNUE]] technology due to support of [[Dietrich Kappe]] and [[Dmitry Pervov]], applied and trained with Komodo games and evaluation <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=75651 Komodo 14.1 Release and Dragon Announcement] by [[Larry Kaufman]], [[CCC]], November 02, 2020</ref>. Improvements for both standard and MCTS mode are expected in the 150 to 200 Elo range. [[Dragon by Komodo Chess]] was released on November 10, 2020 <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=75748 Dragon by Komodo Chess] by [[Larry Kaufman]], [[CCC]], November 10, 2020</ref>.
