Blackmar Diemer Gambit Deflection Beginner Puzzle (Rated 1241): Attack f2/f7 — Mate in 3

This middlegame puzzle shows a classic attacking f2/f7 pattern where the queen and rook coordinate against the enemy king’s shelter. The key idea is to use forcing moves that drag the king into a worse square and then exploit the weakened back rank and open lines. In positions like this, material count matters less than king safety and piece activity, especially when the defender’s pieces are overloaded and the king has few safe squares.
