English Opening Other Variations Trapped Piece in Chess

In the english opening other variations trapped piece motif, a piece (often a knight or bishop) becomes short on safe squares because the English setup restricts its escape routes.

The trapped piece theme is about converting that restriction into a win of material or tempo.
