More Henka Waza
Peter did a bunch of Henka and kaeshi waza. Most of it was pretty straightforward. There was one henka waza where he started with doing an ikkyo and ended up with a sankyo. When I did it I was completely natural for me to do it one way... However, I knew that I was sending uke back to where he attacked from. Peter's version had uke moving in a straight line ending up on the other side.
After a few cycles I finally figured it out. He stepped back and moved uke in front of him more to set up the sankyo. Once I figured that part out, I could do it Peter's way.
