Parry from High Guard 1

Parry from high guard against an attack to the defender's upper left opening.

Canonically these are performed from reverse grip, but variations can be extrapolated from the orthodox grip.

Meyer also says we can extrapolate a variation of this for attacks to the upper right opening.
