Da Lu; Large Rollback

Dave at Formosa Niejia has given me a homework assingment. In the previous post, we are doing some free-style push hands. My opponent is very strong, and is able to move into my center in a very rooted position. This forces me to back up and fight from a defensive position, and I am constantly loosing ground.
Dave has suggested I work on my large rollback as a defense, and it is a great suggestion. Here is part of a two-man form that utilizes the large rollback. The video is with Sam Masich, a great instructor from the Vancouver B.C. area. We were fortunate to have a push hands class with Sam several years ago, and he is a very skilled practitioner. This shows a nice example of how neutralization is used in Tai Chi Chuan, not force-against-force. Yielding and redirection of the opponents force and energy.
