These diagrams show custom pieces and known Fairy-Stockfish built-in fairy pieces from White's perspective on a compact preview board. Some special moves, especially hoppers and game-state-dependent moves, can still depend on blockers or game state.

# OVERWRITE THE KING
# We assign the standard 'k' character to the king slot. 
# The magic is in 'mK': 
# 'm' means move. 'K' means King. 
# Because we didn't include 'c' (capture), the King cannot take anything!
king = k:mK
