Regaining Material With Discovered Attacks Puzzle: Regain — Material

A discovered attack occurs when one piece moves away and uncovers a line attack from another piece. In this chess endgame, the knight is both a blocker and a tactical target, so its movement changes the position immediately. Black can reveal pressure against the knight while creating a chance to recover material. The key idea is to compare the value of the threatened piece with the material available elsewhere before choosing a capture.
