I came across some old notes for a big club system that mentioned that after opening 1C they played "Archimedes over one level intervention"

Does anyone know what this is? It might be of Australian origin?

Thanks in advance

Never heard of Archimedes over a big club. Alan Truscott is said to have invented the Archimedes double 2♣ - (2♥) - X with 2♣ strong, artificial and forcing. It shows 0-3 point, while pass is 4+ and forcing to game.The double is intended to show the responder is so weak that an opener intending to rebid 2NT may not have game so would be wise to pass for penalties if possible. It is said that he thought of the idea in the bathtub. Rumors that he ran naked through the city streets shouting Eureka! are highly exaggerated.
