4 is not for chest, and 6 is not for shoulder. It depends on where your hand is in relation to what is being attacked. If I attack your chest when your hand is way over in 4 already, you are going to take a 6.
Thank you! Please make more videos about parry, because I'm a beginner and that's the one I most struggling with. Also explain the other numbers. (for foil and epee)
I learnt so, you have to finish the parry until you finish the backward step, so these are simultaneous actions. In a middle distance situation, you cant move away from a fast lunge with one backward step, you also have to parry.
It can be. Pronated 4 is really an epee thing, to maintain opposition on riposte. But if you fence both foil and epee, you will tend to start doing it pronated all the time.
