Akira Chess Engine

Primary LanguageRustGNU General Public License v3.0GPL-3.0

First edition.

It works fine, but... there's still a long road ahead!

Approx. CCRL rating: 1750

Progress status:

Pre-calculations - Complete!

Board - Complete! (~24m nps on perft)

Engine - Complete! (~300k to 800k nps; Inspired by: BBC engine)

Eval - Complete! (Inspired by: Kaissa engine, also used PeSTO eval)

Comms - Partially complete (Musthave features work, xboard protocol only)

TODO:

Full UCI support, host it as a lichess bot

Resolve issues (incompatibilities, enhancements, there are a lot)

Opening books and endgame tables support

How to set up a game:

  1. Download and install xboard (WinBoard) or any interface with CECP v2 protocol supported

  2. Add Akira CE latest .exe from github releases (e.g. http://hgm.nubati.net/xboard/winboard/help/html/20.htm)

  3. Options -> Common Engine Settings, set Hash Size as 512 MB (it's hardcoded for now, sorry)

  4. Set time controls to whatever odds, you may also want to disable pondering in Options -> General.

  5. Enjoy!
