Hi Derek Pushing forward on the stick only increases the nose wheel weight and lessens the likelihood of a change of direction.
It must be full back stick, full aileron and full rudder in the direction of the down-wing. What I do not know (regretfully, have been instructing in nose-wheel 2-seaters for 12 years so I should have discovered this by now) is the speed below which the elevator becomes useless. We do teach full back stick 2 pointer touch down and to hold the stick there for the rest of the ground roll - to reduce the vibration damage from the nose wheel on our rough airfield and maximise drag. At some lower speed (after landing) initiating a ground loop becomes problematic. I wish I knew that speed as it delineates decision time to initiate a ground loop.
