Bird Opening Pin Chess Puzzles

A bird opening pin is a pin motif that appears in positions from the Bird Opening, usually after 1.f4 when White has weakened the e1-h4 diagonal and often develops the bishop to g2. The defining idea is that a bishop, rook, or queen lines up on a piece in front of a more valuable target, so the pinned piece cannot move without exposing the king or queen behind it.
