This release contains many small improvements, but the largest ELO gain came from the new mobility evaluation 🤸

The Web App version of Wasabi Chess can be played here.

Changes

  • Add mobility evaluation
  • UCI: output mate distance as score when a mate was found
  • Evaluation: provide bonus for pawns covering pawns and knights
  • Adjust piece and move ordering values
  • Slightly increase LMR threshold
  • Simplify and tune futility margin calculation
  • Directly jump to quiescence search for futile positions at depth 1

Installation

  • Download and unpack the archive for your platform (Linux or Windows 8/10)
  • Configure your UCI client (e.g. PyChess, Arena, cutechess)
    • … on Windows ⇒ to run wasabi.cmd
    • … on Linux ⇒ to run wasabi

⚠️ the bundled WAVM runtime is not compatible with Windows 7 - a workaround is described in the Wiki
