Passai (披塞) in Okinawan styles and Bassai in Japanese styles. The kata focus on the idea of changing disadvantage into advantage by strong and courageous response, switching blocks and differing degrees of power. The feeling of kata should be precise, with fast execution of technique and attention given to appropriate balance between speed and power. The Passai was one of the first Chinese kata forms on Okinawa. (http://en.wikipedia.org/wiki/Bassai_sho)
