Well, the admin has been e-mailing me, saying I should post, so here goes.

Many times when people talk about punching, they also bring up the subject of proper hand position. ... Some prefer to punch horizontal, some vertical and some in-between, more on a 45 degree angle. ... Do you have a preference?
I use a natural punch. Take the exact posture you'll be in at delivery of the strike and, with a relaxed arm and hand, point at your target. The angle of your pointing hand is the angle your fist should be at when the strike delivers. No unnatural twisting, which induces tension and inhibits speed and power, while misaligning every joint in the punching arm (including the shoulder girdle).

I think the point is often missed and people focus on the hand rather then what is important, which is alignment. As soon as you twist the forearm to make it vertical or horizontal you screw that up. Fist angle is dependent on your shoulder.
Yes, sir, primarily, though I would include the entire posture in this stateement. As posture changes, the natural alignment of the fist changes as well. Interestingly, the natural alignment also tends to keep the two large knuckles in the lead and generally positions the fist to better fit into it's target.
Boxers- what is being forgotten in the discussion of a boxers punch is that they fight from a completely different posture than we do. Their strikes and targets, and the area they have to protect, is defined by rules. They don't have to worry about kicks, low blows, grabs or even frictional pulls. And their hands are taped and heavily gloved, so they get away with strikes that would (and frequently do) dammage their hands in a real fight. They shrug their shoulders up and tuck their chin to protect the head better. The horizontal fist is a natural delivery from this posture. Try it and see for yourself. It just feels right- relaxed, powerful, very fast.
We don't fight like that. Our posture is upright and our shoulders are rounded down (at least for most of the martial arts systems I've seen), and our hands are not protected. That horizontal fist is, in most cases, not a naturally aligned punch for us, and throwing it will misalign your shoulders and arm. The shoulders will raise, the elbow will rotate out ("fly"), and the radius will twist around the ulna. There is little supporting structure, and you are overloading the radius in the strike. It will erquire tension to force this unnatural action, and even the arts that are insistant on teaching this strike will tell you that tension destroys speed and power. You'll also hit too often with the small, easily dammaged knuckles.
Forcing a vertical fist does not seem to be as bad as the horizontal, but still has some similar effects. I prefer to allow the fist to travel a natural path, with no induced tension. It rotates to position as it travels and my supporting posture changes, driven by my stance change. As I strike through the target, the stance continues to change and the fist continues to rotate, naturally. This is an uninhibited whole body delivery. If I want my fist to fit into a target differently, I would change posture to support that aplication, or use a different waepon.
My opinion, based on experience with neck and shoulder problems, interviews with therapists and doctors, research and discussions with some very knowlegable martial artists.
