Kings Gambit Declined Keenes Defense Promotion in Chess

In the Kings Gambit Declined Keenes Defense Promotion, Black accepts the Keene Defense structure after declining the gambit, then the game turns toward a pawn-structure race where one side’s passer can advance to promotion. The defining feature is the Keene Defense setup (with Black’s pieces aiming at the queenside/center) combined with a later pawn thrust that creates a promotion threat.
