I don't think there is one move that will get you through every type of skiing. However, there is one big difference between expert skiers and intermediate skiers when initiating a turn. The vast majority of skiers do not know the simple, easy moves to start a turn, and instead they add in all sorts of extraneous motions typically with the upper body. All it takes are some very subtle motions with the lower body that are almost imperceptible which in essence tip the ski and keep it from steering off course. So, if there had to be a magic move, this would be it. What is that move? Despite all the experts, I doubt people would agree. There's a big ankle contingency here, though if an expert buckles down their boots, they can still make some sweet turns. There are lots of great skiers that ski without cuff slop. And without cuff slop, there's not much the ankles can add to tipping, though they add to steering. However, if you magically made it impossible to move your femur, i.e. knee angulation, you might be in trouble. I would even say that ankle advocates aren't even aware how much knee angulation they use, and where'd they be without it. Bam! shot across the bow, bring it on. So, the magic move is knee angulation. Knee angulation does not mean bending the knee sideways. It's like what Wallyk refers to as pointing the knee where you want to go.
