it actually was possible to pull of the manouver of doing a powerful thrust, only not with a pike, it was mostly used with a shorter spear, and the thrust was propelled with the left foot. I did make one mistake though
, this was NOT used against other spearman formations, but rather in smaller skirmishing battles where when infantry charged on the spearmen they would burst out to put even more speed onto the spear, sort of like when one car crashes into a parked car doing 60, or when 2 cars crash into each other head on both doing 60. This was as i said, only possible with spears, and they had to be a bit shorter at that, so that you could pull back fast enough. Remember that behind the first rank there was a second rank with their spears over the first rank's shoulders, and their spear points only about 2 feet behind the first ranks spear points, and after the first rank thrusted, they only had to walk back about 2 feet and then they were safe enough to re-form.
