Yes, sounds like you got the idea. An awful lot of airplanes end up on
their nose (particularly Supercubs for some reason) because the pilot
turns downwind quickley using a bit of brake at the same time.

Some quick ways to get a taildragger up on its nose:
-Using lots of brake in the rollout without using elevator to maintain
attitude. And holding the brakes on hard even when the speed is gone.
-Taxiing too fast downwind and either losing control (no airflow over
the surfaces; got to fly a taildragger all the time, remember?) and
initiating a groundloop, or turning too quickly out of a tailwind. The
wind against the side of the fuselage, under the upwind wing and under
the stab combines with centrifugal force to lift a wheel, whereupon
the downwind wing drags on the surface, and now that more wind can get
at the wing and stab, there's more lift, the tail comes up, and
inertia through the CG and against the dragging wing does the rest.
-With CG forward (nobody in the back), doing a runup without holding
the elevator back will lift the tail of many taildraggers. As the tail
comes up, the angle between the CG and the locked mains decreases so
that the tail gets even lighter, and over she goes. Happens if the
pilot has his head in the cockpit and isn't paying attention to what's
going on outside. Can happen, too, if the pilot is trying to taxi
through deep snow or gooey mud.
