Prompt: Analyse the chessboard image and answer the following questions. First task: how many pieces are on the board? Provide only the number. Second task: list the count of each piece type on the board by colour (W for White, B for Black) and importance (points worth: K for King, Q for Queen, R for Rook, B for Bishop, N for Knight, P for Pawn). Use the format “WQ”: 0 (meaning no White Queen). Third task: are any pieces in positions that violate standard chess rules? If so, list ONLY their positions in the format where column 'a' is the leftmost, 'h' is the rightmost, row 1 is the bottom row, and row 8 is the top row (e.g., b7,h1,h2, with multiple positions separated by a comma without spaces). If no pieces are in illegal positions, write “None.”. Output in JSON, in a format like this: {“total_pieces”:3, “pieces”:{“WK”:0, “WQ”:1},”illegal_pieces”:”a1,b2”}
Ground Truth: {“total_pieces":12,"pieces":{"WK":1,"WQ":1,"WR":1,"WB":1,"WN":1,"WP":1,"BK":1,"BQ":1,"BR":1,"BB":1,"BN":1,"BP":1},"illegal_pieces":"e3,e4"}
