What I said about not looking at the eyes actually applies to more than just modern fencing. I took a class in both modern sport fencing, historic battlefield (sword and shield, sword alone, and two-handed- mostly using the Tallhoffer text at the time), as well as historic duelling focusing on several Italian schools, a Scottish smallsword school, and Spanish duelling.
Want to hear what's weird? You can make your eyes lie. I had an instructor that could relax his eyes so that it looked like he was either staring at a point five feet behind you or a foot in front of you. He was taking in everything- both hands, legs, body, you name it. Creeped most people out, because it meant that they couldn't read the eyes.
You still have some peripheral vision while wearing the mask, and it was strictly for safety reasons as we were employing shinai's and engaging in controlled contact strikes.
Also, there is a Spanish style of rapier (name escaping me at te moment), where it is possible to be looking in one direction, take a half-step to fool the opponent into thinking you are lunging that way, then a quick cross-step in the opposite direction. If executed properly they have hit nothing but air, and your blade would have passed through their brainpan.
Example two: I'm looking at your leg. I continue to look at your leg. I can see what you are doing in my peripheral vision, but I'm looking at your leg. I'm looking at your leg. I'm thrusting at your face. This works because I know where my opponent is.
Finally- there is a fun trick lost to modern fencers called the cross step. One of the key lessons drilled into us was that of distance. Using it, controlling it, making it work for us. This dealtj with fooling the enemy into thinking you were x distance when really you were y distance. A lot of this had to do with how your feet are positioned, as your distance is measured off your planted foot, not the foot you are lunging with. I'm right handed, so my planted foot is typically my left foot. If my left foot is in front of my right foot, I'm much closer to you than you might realize, and if I catch you while you have the right foot in front of the left, then I can hit you and you can't hit me. Alternatively, I can do a half-lunge but end in a position where I can still gain an extra few feet by executing a second quick lunge while you arestill adjusting tothe fact that I'm not as far as you thought I was. (In game terms, this might be considered the equivalent of a feat that gave a Wis or Int bonus to AC). Hmm.. not sure how much use any of this, but I find it interesting at least.
Bregales- errr... you do know that there are quite a few moves where you end up with your back to the opponent, right? Not as a starting point for sure, but I can think of at least one two-handeded exchange that ends with the you having your back to the opponent, and the opponent has skewered themselves. Also thinking of a few grappling techniques that end where at some stage your back is pressed to the front of your opponet.
Example: Opponent throws punch, you avoid so it passes over your right shoulder. Grab arm, spin to reverse, and throw your opponet over your shoulder. And yes, I'm picking at nits here.
Yes yes, I know I'm preaching to the choir here and/or talking gibberish, but dangit, I miss fencing.
