Center Game Pin Chess Puzzles

A center game pin is a pin that appears in the Center Game, usually after 1.e4 e5 2.d4 exd4 3.Qxd4 or 3.Nf3, when pieces and pawns line up around the central files and diagonals. The defining feature is that a piece in the center becomes pinned to a more valuable target, often the king, queen, or a key defender, because the open center gives the pin immediate force.
