Scholar's mate was named and described in The Royall Game of Chesse-Play, a 1656 text by Francis Beale which adapted the work of the early chess writer Gioachino Greco. [1] The example given above is an adaptation of that reported by Beale.
In warfare, it is a military tactic to defend against a mobile armoured attack, or blitzkrieg. The defenders deploy in depth in heavily fortified positions suitable for all-around defence. The attackers can penetrate between the "hedgehogs", but each position continues to fight on when it is surrounded. That keeps large numbers of attacking ...
The maneuver was used in the blitzkrieg of the armed forces of Nazi Germany during World War II, developing into a complex, multidisciplinary endeavor. It involved fast movement by mechanized armor, artillery barrages, air force bombardment, and effective radio communications, with the primary objective of destroying enemy command and control ...
In chess, a cross-check (or counter-check) is a tactic in which a check is played in response to a check, especially when the original check is blocked by a piece that itself either delivers check or reveals a discovered check from another piece.

Blitzkrieg was not a doctrine, or an operational scheme, or even a tactical system. In fact, it simply doesn't exist, at least not in the way we usually think it does. The Germans never used the term Blitzkrieg in any precise sense, and almost never used it outside of quotations. It simply meant a rapid and decisive victory (lightning war)...
