Pin Puzzle (Rated 1570): Win Material — Skewer
A skewer attacks a valuable piece while creating a second target behind it. In this middlegame, White’s bishop is under pressure, but active piece placement changes the tactical balance. The key idea is to improve the bishop while increasing pressure around the exposed enemy king. This creates a dual threat: the opponent must address the king-safety problem while still accounting for the attacked piece. Strong tactics often begin with activity, not an immediate recapture.
