For
Four-player Teams chess engine developers
Worth noticing
PhoenixNet uses separate own-king and partner-king feature streams, with 65,280 sparse input features and 17 king buckets.

Field notes

The page describes a fixed four-player turn cycle: Red and Yellow share a team, as do Blue and Green. Its evaluator is team-relative, and the documented PhoenixNet format separates own-king and partner-king feature streams. The homepage lists support for FEN setup, castling, promotion, and en passant, and gives build requirements of CMake 3.24+ with MSVC, Clang, or GCC.
