Pin Puzzle (Rated 1240): Win with a Pin — Middlegame Tactics

This middlegame puzzle shows how a pin can turn a seemingly active position into a tactical collapse. White appears to have extra material and a dangerous passed pawn, but Black’s pieces coordinate to create forcing threats against the king and key defenders. The lesson is that material advantage is not enough if your pieces are loose and your king is exposed. In classical chess, a single tactical shot can flip the evaluation immediately.
