About this opening
The Bogoljubow Defense (5...g6) prepares the g7 fianchetto to control the long diagonal and defend the black king against the Blackmar-Diemer attack. Black aims for solid development and absorbing White's kingside pressure. It is one of the most natural replies to the gambit, combining king safety with keeping the extra pawn.
