Englund Gambit Declined Reversed French Back Rank Mate in Chess

The englund gambit declined reversed french back rank mate is a tactical back-rank pattern arising from an Englund Gambit–type sacrifice where the opponent declines, and the resulting structure resembles a “reversed French” setup. A defining feature is that Black’s pieces line up on the kingside while White’s king stays vulnerable on the back rank, often after the f- and g-pawns are locked or removed. The mate usually comes from a forcing sequence (checks and/or a rook lift) that exploits the fact that the king has no escape squares.
