Back-Rank Mate
A checkmate delivered along a player's own first or eighth rank, typically because the king has no escape squares.
Back-rank mates are common when a king is castled behind its own pawns with no flight squares and the defending rooks or pieces have been removed or overloaded, leaving the rank fatally undefended.
Etymology
The name is a plain English compound; the chess sense of “rank” — one of the rows of squares across a chessboard — is itself attested from the 1570s, descending via Old French renc/ranc from Frankish *hring “ring, circle.” No source consulted documents who first wrote “back-rank mate.” The best-documented naming for this mating pattern is in fact its French rival: Edward Winter traces “corridor mate” to Georges Renaud and Victor Kahn's L'art de faire mat (Monaco, 1947), as “le mat du Couloir,” Englished as “corridor mate” in The Art of the Checkmate (New York, 1953). Winter's lexicology material cites the phrase “back rank mated” only as late as Mike Basman's Chess Openings (1987), and then as a criticised barbarism, not a first use.
First documented: 1947 — Georges Renaud & Victor Kahn, L'art de faire mat (Monaco, 1947) — for the rival French term “le mat du Couloir” / “corridor mate”
