Thanks NIKK...seen them before, but didn’t know how they were used in chess.
I’m beginning to think the chess board is the “MAP”. Could the numbers in the kill boxes represent “pieces” on the board??? Hmmmm...I’m gonna have to see the highest number in a kill box and how many chess pieces.
Castling is an important goal in the opening, because it serves two valuable purposes: it moves the king into a safer position away from the center of the board, and it moves the rook to a more active position in the center of the board (it is even possible to checkmate with castling).
