Tai Chi Chuan: Needle To Seabottom vs. Fan Through Back vs. Play Guitar

Here we are again experimenting with various combinations of Tai Chi Chuan techniques. This time we start with "needle to seabottom" as a joint lock. This is countered by "fan through back"- an unusual version. You really have to counter the joint lock before it is completely set or you are screwed. In this version, you drive the locked hand/wrist upward while pushing up on opponent's elbow/tricep. The opponent counters by moving off-line and locking the elbow in "play guitar/raise hands" (depending on which side is forward).
Once again, the idea is to flow and keep the continuity of the pattern.
