I had put a gi on my dad whose focus has been mainly taijiquan with some early study of Shaolin “hard” style a while ago and he used my lapel grip as a trapped hand for a common fixed step push hands uproot. I managed to use that in judo as kuzushi leading right back the opposite direction into a shoulder throw. Cool. Took about one and a half months til I got the opportunity, but some of my planned attempts from cross-training are working. Very encouraging so far.
