Not really a radical plan, just Schlieffen redux. Schlieffen was the real visionary, but it took Tanks to make his plan work, and he damn near won it all on the Marne in 1914 anyways.
The “Schlieffen redux” was the original plan to attack France in 1939/1940.
The “left hook” running the panzers through the Ardennes was the “radical” plan. Nobody expected the French and the Brits to cave so fast.
