Insufficient Material Draw Puzzle (Rated 1500): Win a Passed Pawn — Chess Endgame

This chess endgame revolves around a dangerous passed pawn and a rook that must stay active to stop promotion. White’s advanced g-pawn is the key asset, but it is also vulnerable to precise rook checks and king activity. The side to move must use forcing moves to improve the king, keep the enemy king boxed in, and create a situation where the rook can capture the pawn at the right moment. In classical chess, these technical endings often hinge on tempo and coordination.
