Cross-Check
A move that gives check in reply to being checked, rather than blocking, capturing, or moving the king out of the original check.
A cross-check is particularly powerful because it can render the opponent's own check irrelevant, since a player in check must resolve it before doing anything else, including capturing.
Etymology
Edward Winter's compilation of earliest occurrences of chess terms, drawing largely on Oxford English Dictionary research and his own Chess Notes, records a nineteenth-century citation for this one. He quotes Arthur F. Mackenzie's Chess: Its Poetry and Its Prose (Kingston, 1887), page 133: let us now compose an attacking version of the well-known counter or cross check idea, filed under Chess Note 7607. The wording well-known indicates the idea was already established in problem circles by 1887, so this is a first known citation rather than a coinage. Wikipedia's glossary defines the move plainly as a check given in reply to a check. No language of origin beyond ordinary English, and no inventor, is claimed by any source consulted.
First documented: 1887 — Arthur F. Mackenzie, Chess: Its Poetry and Its Prose (Kingston, 1887), p. 133, cited in Edward Winter, Earliest Occurrences of Chess Terms (Chess Note 7607)
