A clinic with John Kerker - my notes on kata application studies that day


Saturday October 23, 2010
Clarence Whitley’s Dojo in Chicopee, Massachusetts
A clinic with John Kerker


 



 

Application and Technique studies


Attacker RFF Seisan Right Punch
Defender RFF Seisan – done at normal kata execution speed. You step outside of the range of their inward strike (ghost technique).

Attacker RFF Seisan Right Punch
Defender RFF Seisan – done at normal kata execution speed. You step outside of the range of their inward strike (ghost technique) and as you do so your open hand palm reaches out and slides back to your shoulder, moving the attack away from you.
This is identical to the opening of our blue belt first waza. The parry came from E. Rothrock’s Pai Lum techniques.


Seiunchin technique study

Attacker LFF Seisan Left Punch
     Exterior Line of Defense
Defender RFF Seiunchin dachi (outside of their attack) and as you do so you execute a simultaneous double arm strike. Your right hand crosses your body to vertical strike into the side of their arm (about the triceps insertion). At the same time execute a left vertical strike into their ribs.
Then your left hand comes up inside their arm, you bend your elbow and pull back. At the same time you chamber your right fist (and you might alternatively slice that fist back across their ribs as you chamber.
You then slice a left backfist into their jaw.
Conclude with a right vertical strike into their thigh, straight into their leg bone.


Attacker RFF Seisan Right Punch
      Interior Line of Defense
 Defender RFF Seiunchin (inside of their attack) and as you do so you execute a simultaneous double arm strike. Your right hand crosses your body to vertical strike into the inside of their arm (about the biceps insertion). At the same time execute a left vertical strike into their ribs.
Then your left hand comes up inside their arm, you bend your elbow and pull back. At the same time you chamber your right fist (If they’re executing their 2nd strike, if the left pullback does not move them enough your chambering right hand can slice into their left striking arm.)
You then slightly rotate counterclockwise and pull them forward
Conclude with a right vertical strike into their head or back of their neck (practice past the back of their head). / Alternately a right vertical strike into their inner thigh.


Variations of takedowns with arm bar across the knee locks at the end. 


Wansu Technique study – the underlying principles are almost identical to the Seiunchin ones.



Attacker LFF Seisan Left Punch  - Interior Line of Defense
RFF Right outer parry.
Attacker RFF Seisan left chambers as they Right Punch
Right open hand cross parry as the left vertical punch strikes into their lower ribs.
Attacker Left Punch
Left hand rises outside of their right arm, your left foot steps back behind your right and you left down block across their arm rolling them down. As this occurs your right hand chambers and can slice across their striking arm during the chambering. Their left arm cannot hit you.
With your arm bend their arm in at the elbow and lock it to your chest.
Right strike to their head.

Attacker LFF Seisan Left Punch – Exterior line of Defense
RFF Seisan Right open hand cross parry as the left vertical punch strikes into their lower ribs.
Left hand rises outside of their left arm and then low blocks down across their arm as your left foot steps back behind your right. Simultaneously your right chambering hand might slice across their face as it chambers.
Conclude with a right vertical strike (from chamber) into the side of their thigh (strike to the bone).


 Variations of takedowns with arm bar across the knee locks at the end.


Alternate techniques – Kerker Sensei would at any time take the technique being shown and run multiple variations, all with skill and no apparent set up time, naturally going from version to version.  For example he might add a right front kick to the attackers stepping ankle and then begin the technique. This works right into the depth of application potential Harrill Sensei taught, an shows the skill he imparted to Kerker sensei.

Teaching note – I observed several black belts reach the babble complex, too many variations and getting lost in the hand movements and forgetting the lower body stepping or shifting. I helped them gain control by suggesting that they forget the application and just perform the kata until they got the full body movement down, then they connected with the upper body applications successfully.


Shimabuku Sensei Self Defense Techniques – John explained the history of these teachings and then demonstrated some of them.
 

Comments on Sanchin.

John explained one year at the August rodeo training week the individuals there wanted to see Sanchin, so John asked to see their Sanchin kata first. It became a ‘contest’ of who could breath hardest and tense during execution greatest. They then asked to see John’s Sanchin. He simply ‘walked’ forward and executed lead hand strikes, one after another.
{Demonstrated for us and I have on video.} simply striking using Sanchin power.


Then he demonstrated Seisan using Sanchin.

Finally he described his favorite video of Harrill Sensei performing Sanchin, which incorporated Goju and Isshinryu techqniue.

Back when Harrill Sensei described doing an 8 hour clinics on Sanchin to me, while I wished I could have attended it, this is a bridging moment to those events.


Attacker LFF Right Punch
RFF Right (starting from high X) the right descending knife hand slices across the attackers arm
Attacker Left Punch
Right backhand rising and descending strike across their left arm.
Right Seisan grab to their upper arm (or throat)

   Note the first two slices are done with great smashing power into their arm.



Isshinryu seizing – John Demonstrated the use of the vertical fist for seizing and twisting flesh for the pain effect. He described the method of training Harrill Sensei using the makiwara, but rather than strike to press and hold the fist there to strengthen the inner hand grip.

 

Use of the X Block

John described a simple use of the X block (the actual X is a momentary structure)



Attacker RFF Seisan Right Punch
LFF Seisan left cross open hand parry
Right hand rises counter-clockwise and rolls across the attackers arm
    As the right rolls down the momentary X is formed.
    The right downward press locks their arm to your chest.
    Left open hand strike to the outside of their face at the cheek bone (or neck).



A favorite technique



Attacker LFF Seisan Left Strike
RFF Seisan Right open hand cross strike to their arm as the left vertical punch strikes into their lower ribs.
Raise your left arm outside their arm, pivot on your right foot and step 90 degrees to the left, your right foot behind the left, but not in kake-dachi, but placing your right foot completely flat on the floor. This draws your center back
As you’re left foot sets you complete pulling your left arm back (or down with a low block, totally pulling the attacker off balance. You’re behind them, they can see what happens.
Immediately clip a right cross to their jaw.


Variations of takedowns, such as your right drawing across their lower jaw and then arm locks across your knee.




Personal Note: from 76 to 77 I trained in Tang Soo Do for two years. That school had a good Makiwara and I used it before and after class every day, on my own violation. It was interesting to note the calluses on the inner pads of my palms from the clenching of the fists while striking.  From that time on for years whenever I gave a solid body shot my partners ‘felt it’. I now see a parallel to the training John Kerker describes, but while I worked the makiwara I was unaware of it’s potential contributing factor.

An interesting lesson to learn.
