Learn How to Win with a Long Pin: Endgame Tactic
This puzzle is a classic example of a long pin in a practical endgame-like middlegame. White’s heavy pieces coordinate against the enemy king, and the key idea is that one defender is tied to the king by a line piece, making it impossible to recapture freely. Once that defender is overloaded, the position collapses through a forcing sequence that wins material and simplifies into a dominant queen endgame or winning liquidation.
