The strange problem of the left hander...

Last night I put together a lesson on fencing left handers. It's a fact that there is always a bit of a mystique around left handers, mostly due to their comparative rarity and also that they do offer a genuinely different set of problems to overcome. I mean this in a nice way - I know some left handers who are quite nice people....!
I can't really go through the whole lesson as it actually involved doing some practical but here's a synopsis for those who wish to read it. Conventional right-vs-right techniques will not work so well with a left hander. For instance a direct lunge is more likely to be parried because a left handers foil is already virtually in contact with a right handers and has less far to travel to make the parry. Correspondingly any feint disengage actions need to be much more accurate if they are to succeed and are only likely to do so if the feint starts on the outside of the blade.
So if conventional techniques won't work what will? Let's consider the unconventional. For a left hander with a high guard an attack into the hip below the sword arm can reap benefit. Even if the opponent parries into octave you can disengage and finish high to deliver the hit. For a low guard position you can consider the cut-over attack into the left shoulder area or possibly a pronated attack into your line of quarte (Are you still following this?). A beat from the outside of their blade with the lunge made over their arm and blade can also be effective.
The most important thing to think about with left handers though is to not adjust your mental game plan. By all means adjust your tactics but don't let the fact that their arm is in the wrong place affect your intent and confidence. "oh no, they're left handed" is a common mental reaction; perhaps a more appropriate one would be to have no reaction at all.
