Coco v1.1.1

A focused follow-up to v1.1.0 that completes the singular extensions feature and updates the engine identity.

Highlights

  • Singular Extensions (double-extension): The singular verification search now grants a +2 ply extension when a TT move is strongly singular (verified well below the singular bound) on non-PV nodes. Cumulative double extensions are capped at 6 to prevent runaway depth inflation.
  • UCI Engine Name: The engine now identifies itself as Coco v1.1.1 in UCI handshake.

Assets

  • coco-chess.exe — statically-linked Windows build (no external DLLs required).
  • coco.nnue — the paired neural network weight file.

Requirements

  • A CPU supporting AVX2 (built with -march=native).
  • Windows (x64).
