"I am deeply moved by the style of Komodo. In my opinion it's the perfect combination between computer accuracy and human positional understanding. I get the feeling it's taken positional understanding to the next level. After such an impressive performance I am going to test Komodo in my future work, especially in very positional play, and am really looking forward to working with it."

- GM Boris Avrukh

"I am extremely impressed by Komodo's play. I watched and analyzed every game and it was absolutely flawless positional chess, the likes of which has never been seen before by an engine... or human. Komodo clearly outplayed the other programs in the TCEC tournament."

- GM Roman Dzindzichashvili

The World's #1 Chess Program!!

Komodo is at the top of all major chess rating lists (CEGT, CCRL, IPON) and is the reining TCEC champion.

Description

Komodo 10 is about 15 Elo stronger than Komodo 9.4, and is expected to top most of the rating lists. Gains come from improved search, evaluation, time management and more efficient use of multiprocessing.


Komodo is  three-time TCEC champion, the most prestigious online computer chess event, and has also won several CCT events. Komodo has won a four game match giving various substantial handicaps to World Champion Candidate and U.S. Champion Hikaru Nakamura.

Komodo supports Syzygy tablebases and is available for Windows, Linux, Mac and Android.

 

Features

  •  Evaluation developed by a Grandmaster
  •  Multi-core support (up to 64 cores)
  •  Syzygy endgame tablebase support
  •  Chess 960 (Fischer Random Chess) support
  •  'Persistent Hash' lets you save Komodo's analysis of a position so you can come back later and resume analysis, saving you time
  •  'Dynamism' (new) lets you control how willing Komodo will be to make long-term sacrifices of material or pawn structure for dynamic play.

Komodo 9 (May 6, 2015)
  • Komodo was modified to ignore GUIs that repeatedly send the same commands. This was done to deal with the Aquarium GUI, which sends repeatedly sends Chess 960 commands with each new move. When receiving this command, Komodo 9 thinks the game type is changing, and clears its hash table, which reduces play quality.
  • The sudden death time control was improved.
  • The Windows 32 bit compile was modified to properly handle multiple threads.
