Ruy Lopez Berlin Defense Intermezzo Chess Puzzles

The ruy lopez berlin defense intermezzo is a tactical idea that appears in the Berlin Defense of the Ruy Lopez, where one side inserts a forcing in-between move before recapturing or continuing the main line. In this opening, the defining feature is often a check, attack on the queen, or other tempo-gaining move that interrupts the expected sequence after 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6. For an intermediate player, it means recognizing that the Berlin endgame or early middlegame can contain a hidden tactical shot instead of a simple exchange.
