Kings Gambit Declined Keene Defense Trapped Piece in Chess

In the Kings Gambit Declined Keene Defense, Black accepts the gambit structure and often develops in a way that can leave a piece short of escape squares. The “trapped piece” motif appears when White’s attacking setup (often with tempo-gaining moves) restricts Black’s minor piece—commonly by controlling its retreat squares and forcing it into a constrained position. For an intermediate player, the defining feature is the combination of pawn structure plus move order that denies the trapped piece an out-route.
