There is a 64 square chessboard. A pawn is at some position on the checkboard. There are only two players on the checkboard: the pawn and king of opposing team.

Prove that if King is outside the square, it can never stop the pawn from promotion (reaching the last rank).(adsbygoogle = window.adsbygoogle || []).push({});
