Komodo 10.1 -- 2016 World Champion edition

price:

"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!!

Version 10.1 is the version which recently won both the 2016 World Computer Chess Championship (despite a 50 to 1 hardware disadvantage?!) and the 2016 World Software Chess Championship, and is the same version that won the 2016 World Rapid Computer Chess Championship with an incredible 97% score. It also defeated a strong grandmaster 3 to 1 despite giving a two pawn handicap.

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

Description

Komodo 10.1 is about 10 Elo stronger than Komodo 10.


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

  • "Smart Syzygy" is a new setting intended for computers with 6-piece Syzygy tablebases on spinning hard disks (hdd). Accessing 6 piece TB's from a hard drive slows down Komodo a lot. Setting Smart Syzygy to 'on' will greatly improve play if you use a hdd.
  •  Evaluation developed by a Grandmaster
  •  Multi-core support (up to 64 cores)
  •  Syzygy endgame tablebase support
  •  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' lets you control how willing Komodo will be to make long-term sacrifices of material or pawn structure for dynamic play.
  •  'Progress Threshold' (new) lets you control how quickly Komodo starts to worry about the fifty-move rule.

    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.
