Its funny you mention punches. At our club championships last year we used the wtf ruleset but actually scored punches and encouraged them. It was amazing how good it looked, it was awesome to watch and most points were scored by punches. It was also heaps of fun.That still doesn't really answer the questions, though.
I think I know about the guard down, to protect the stomach, which is a major scoring area . . . although more often than not it seems that they don't actually protect anything, they just let their hands dangle at their sides.
Also, punches are allowed, so why don't they use them more? Seems you could rack up points with good, strong punches to the chest.
And just why ARE there so many roundhouses? TKD is known for its DIVERSITY of kicks. Like you said, "think in terms of what it is," so to me that means I should see a wide array of kicks on a regular basis.
