Queen's Indian Skewer Chess Puzzles

The Queen's Indian Skewer is a tactical motif that appears in Queen's Indian Defense structures when a long-range piece attacks a more valuable piece in front of a less valuable one, often along a diagonal after ...Bb7 or ...Ba6. The defining feature is that the queen, rook, or king is forced to move, exposing the piece behind it to capture. In practice, it most often shows up when White's queen or rook is lined up with a bishop, knight, or king on the same diagonal.
