How to configure a position

Two ways to select a position:

  • SP number — each of the 960 Chess-960 positions has a unique number (1–960). Type it to load that position.
  • Position code — type the 8-letter back-rank arrangement from a to h (e.g. NRKBQRNB). The board updates as you type.

SP 386 is RNBQKBNR, the classical chess setup.
