Ruy Lopez Berlin Defense Discovered Attack Intermediate Chess Puzzles

In the Ruy Lopez Berlin Defense, this motif appears when a piece moves or is captured and uncovers an attack from a bishop, rook, or queen on a more valuable target. For an intermediate player, the key feature is the Berlin structure after 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6, where piece placement often creates long diagonals and pinned lines that can be opened by force.
