For instance, we might do low-resistance randori, throwing osotogari any time the other guy points his center away from you or we might do randori looking for hizaguruma anytime the other guy leans over and stiffarms.
What we are really working on here is learning to move around in shizentai and trigger our throws when we see the opponent make specific postural deviations from shizentai. Common deviations to look for include.
- if he turns his center away from you, do deashi or kosoto or osoto
- if he bends over and stiffarms, do hizaguruma
- if uke spreads his legs too far, do kouchigari or ouchigari
- if he lunges for a grip with his dominant arm and leg forward, do seoinage
- if he stands straightlegged on his heels, get ready to do anything named otoshi next time he moves
- if he bends his legs too much, get ready to do anything named guruma next time he moves
