Learn How to Spot a Mate in 1: Portuguese Gambit
This puzzle comes from the Scandinavian Defense, Portuguese Gambit, and it shows how quickly a kingside attack can become decisive when the enemy king is boxed in. Even in a middlegame where one side is materially ahead, a single tactical idea can override everything if the king’s shelter is weakened and key defensive squares are missing. The lesson is to always check forcing moves first, especially when the opponent’s queen and rook are aligned near the king.
