This release revolves around 2 major search improvements - move ordering and extensions.

I have also simplified Berserk's time management. I do not expect any timeouts, but if anyone does see them please let me know

Thank you to Lars for pre-testing this release and confirming this number is reasonable


  • Counter move history and pruning
  • Follow up move history
  • History extension
  • Castle extension
  • Adjust depth on fail high in aspiration
  • Space eval cleanup
    • Credit to Laser for inspiring the resulting code which is MUCH nicer
  • Time management simplification
    • Berserk should be semi-aggressive, but nothing compared to what previous releases are
