Lemming Defense Puzzle (Rated 1328): Fork — Decisive Material Gain

This puzzle shows a classic tactical sequence where active queen play creates a decisive material edge. Black’s queen invades the kingside, attacking multiple loose pieces at once and forcing White into a defensive response. The position is still in the opening, but king safety and piece coordination matter more than development count. When the enemy king is uncastled and key pieces are undefended, a forcing move can turn a small edge into a winning advantage.
