Philidor Defense Trapped Piece Intermediate Chess Puzzles

In the philidor defense trapped piece intermediate motif, a piece becomes stranded in the Philidor Defense because the pawn structure and piece placement cut off its retreat squares. For an intermediate player, this usually appears after Black adopts the classic ...e5, ...d6, and ...Nf6 setup, then uses a timely pawn push or piece placement to box in an enemy bishop, knight, or rook.
