I attended the Saturday session led by special guest Godan James Uyeda Sensei. The entire session had a focus on irimi, the concept of moving directly into an attack with your own attack. It is similar to sen sen no sen (preemptive attack that may include evasive movement and additional “counter attacks”), but more direct in that it, in some way, ignores the opponents attack and moves directly in as if into the eye of a storm. There was also some tangential discussion of sen no sen (block and counter at the same time), including a thought that we should be teaching that from the start and not even bothering with the more basic go no sen (block, then counter) which just builds bad habits and ineffective timing.
