in general if the hand technique is on that side where the leg is in front and/or is the most bended than it is baro. but it's only for stances with an equal weight on every feet. e.g. Gunnun Sogi, Nachuo Sogi etc. but if you have for example Niunja Sogi, baro is on the side where the leg is most bended. The same for Dwibtal Sogi. If you have Gujung Sogi you have equal weight on every feet and both legs are bended the same so baro is where the leg is in front. But don't ask me, where is baro or bandae in Annun Sogi. I don't know. Maybe somebody here in the forum.
I hope that helped.
Learning is a process which never ends and where you have to be afraid to forget what you have learned.
I'm afraid I dont' believe you are quite correct. I may be wrong but to my understanding the definitons are as as follows:
Bara (obverse) is over the primary leg Bandae (reverse) is opposite the primary leg
What is the primary leg? There are three criteria for deciding
the primary leg in any stance. The primary leg is the leg that contains the most
body weight. If the weight is the same on both legs, then the primary leg is the
leg with the most bend. If both legs are bent equally then the front leg is the primary
leg. For example, the primary leg in the walking stance is the front leg. This is
because there is 50% body weight on each leg. Therefore the leg with the most bend
is the important one i.e. the front leg.
With these definitions it is easy to extraploate whether a technique is Baro or Bandae.
