More like Bill has a hard time seperating what he learned and what he stole.%-} I be a martial arts PIRATE don't ya know. ARGGHHH Which is fitting considering the arts I'm drawn too and their history. I guess the favorite stuff for me is the wave, topple, collapse and center of the wheel so I'll cover them. The wave - In Kuntaw one concept we use is called "the wave" You create a void for the attacker to fill and surge into that void with your attack. It should feel like you are a wave pulling out to sea then crashing into the shore. It is a deception concept and a power generating concept. Topple - In Kuntaw allot of movements create a situation where the attackers balance is taken, when the force is applied to them high it causes them to topple. It should feel like they have a pivot in the middle of their body and you apply force to the top causing the bottom to swing up. Collapse - Another balance disruption concept. Like a building being demolished the attacker has his structure broken then overloaded by the upper floors causing him to collapse nearly straight down. It can be started with a head manipulation then your force is applied downward to overload the compromised structure. The damage is similar to building that fell on to itself, the lower levels are crushed by the upper levels. You should be very careful with the collapse in training you can hurt a training partner easily using this concept to vigorously. Center of the wheel - This is a pretty common concept in many arts. In Kuntaw we seek to move into the attack and redirect it while turning like the hub of a wheel. It is very good for strong circular attacks. Like I said these are some of my favorites.
