"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

Introducing the all new Komodo, Komodo MCTS

What they came up with was Komodo 12 MCTS - a engine which searches for candidate moves in an incredible new way, and finds moves no other engine can!?
