I came across this article about Master Whitson in a special edition of the FMA digest in 2006. The edition is titled Filipino Martial Arts at Ang Daga. Zach’s article starts on page 29. Here’s a quote from the article:
The Counterpoint training method develops the student’s ability to recognize position and develop timing in order to change and flow spontaneously in order to achieve the objective. Based on timing and position every technique has counters and re-counters. As the human body moves through the motions and positions of combat the opportunities for countering continuously change and evolve.
That is a succinct explanation of the Counterpoint Tactical Systems, and this article is a good introduction to Zach and his approach to martial arts. I highly recommend reading it.
While you’re there, check out the other issues and look around at the FMA Informative issues as well. FMA Informative and links to the different editions, issues and recognitions can be found on the right hand side of the web page. This is a good resource for the wide world of Filipino Martial Arts.
