The International Day of Sports for Development and Peace is traditionally marked by the Croatian Post Mostar with the issue of postage stamps. In 2023, the theme is chess, one of the oldest and most widespread board games. The chess board is square in shape and divided into 64 squares that are alternately coloured light and dark. In the starting position there are 16 white and 16 black pieces (one king and one queen each, 2 rooks, bishops and knights and 8 pawns each).

            Although the game with this kind of board and pieces has been around since the 6th century, the final rules were established only in the 19th century. One player plays with white pieces and he takes the first move, and the other plays with black pieces. The king can move one square in all directions. While the cannon or rook can move straight, in a linear fashion for one or more fields, the bishop can only move diagonally. The strongest piece is the queen, which unites the move of the rook and the bishop. The only piece that can jump over other pieces is the knight that moves in the shape of the letter L. A pawn can be moved forward one or two squares from the starting square. If he reaches the last square of his row, he turns, at the player's request, into one of the stronger pieces (except the king). The game ends with the victory of one of the chess players or a draw (undecided). (Željka Šaravanja)
