The LLM is prompted to select one of three actions at each turn:get_current_board: Retrieve the current board state, often in a textual format like Forsyth-Edwards Notation (FEN) or a visual representation (e.g., ASCII board).
get_legal_moves: Obtain a list of legal moves in Universal Chess Interface (UCI) format (e.g., e2e4, a7a6).
make_move <UCI move>: Submit a move to be played (e.g., make_move e7e5).
And llm chess competition is not new:
