The Rule of the Square is used to determine whether or not a passed pawn can queen when it is not supported by its own king and the enemy king is chasing it. The idea is shown by the diagram
on the right:
One side of the square is the line that extends from the pawn to the square on which it queens. The rule says: if the enemy king can reach the square of the pawn, then it can capture the pawn; if not, the pawn can queen without the aid of its own king. Remember that if the pawn is on its starting square, it can make a double step, so the square is the same as if the pawn has advanced one square. The rule is valid for all pawns, including rook's pawns.
It is a good way and simple way to see if a pawn can queen. I have personally applied the rule in several matches and has worked every time. There is no need to chace the pawn by using this trick. It has really improved my score at chess. Congratulations for sharing this trick.
ReplyDeleteThis is pretty important rule to be known, it’s necessary when only two kings and a pawn is left. Always argument will rise between the players in queening the pawn, a player with pawn and king must be aware that his game is not pulled by opponent by blocking his pawn. It leads the game to neutral.
