In the 90+ degree days of summer, guard passing in no-gi grappling feels a lot like what I imagine a brown bear feels like when trying to get a hold of a fish:
Maybe I’m too old and slow, but passing the guard of anyone under 170 lbs in no gi is very challenging. It’s tough to turn up the pace and aggression on the pass because I can’t always trust that wherever I put my feet or hands will not slip and result in a knee hitting my face, thereby making me feel like an idiot.
Open guard passing (middle to long range style) and stabilizing the pass to me is the biggest difference between gi and no-gi. It requires an embrace of the scramble, and at the same time an abundance of patience. Definitely an interesting puzzle to try and solve.
