Double Attack
A single move that creates two separate threats at once, such as attacking two pieces simultaneously.
A double attack is often difficult to meet because a single defensive move can typically address only one of the two threats, forcing a concession such as losing material.
Etymology
Double attack is a plain descriptive English compound rather than a borrowed or eponymous term, and no coinage event for it could be located in the sources consulted. Wikipedia's chess glossary defines it as two attacks made with one move, either by the same piece (in which case it is a fork) or by two different pieces, as in a discovered attack where the moving piece also creates a threat. The Wikipedia article on the fork states directly that a fork is a type of double attack, making double attack the broader umbrella category. The noun attack itself entered English by the 1660s from the French and Italian verb attaccare, per Etymonline's entry for counterattack. No dated first appearance of the chess phrase was found.
