Grob Opening Puzzle (Rated 928): Win with a Pin — King Safety

This middlegame puzzle is a classic example of how king safety can outweigh material. White’s pieces coordinate around the enemy king, using a pin and a skewer to force concessions. The key idea is that an apparently active black piece becomes tactically vulnerable because it is tied to the king’s defense. In classical chess, these short forcing sequences often decide the game before any endgame is reached.
