Far and away the best resource for determining the strength/weakness of a position is our body. No one else can do such measuring for you, and it’s why we want to make the transition from copying to principle based comprehension as soon as possible.
Don’t get me wrong, we’re still going to copy to some degree, but when we copy from the space of bio-feedback and principles we mimic to see how things feel, as opposed to getting something ‘right’ by comparison. This self-referential leap represents the start of the artistic phase.
Also, in relation to our training partners, if a offensive position feels like a hornets nest, it’s probably not as ‘offensive’ as we’ve interpreted. Case in point, cross-side or half-guard positions where our weight is centered directly over opponents hips means bucking bronco/underhook defense.
Remember, if an approach is hard, there’s probably a more efficient answer out there. Jiu-jitsu is about being safe and waiting for the right time. Arriving at a destination jacked up and tired in the context of the art of Jiu-Jitsu means you were some combination of mis-informed, stupid, and impatient.
Use nature’s gift of tacticle and structural awareness and be brilliant.
