My statement about Sanda or Sanshou boils down to a set of very simple premises:
IF
Taijiquan IS a Martial Art
AND IF
A person trains it AS a Martial Art
THEN
it should hold its own in open competitions with other styles or even with people doing no discernible or MMA styles.
NOW…
I will grant that understanding HOW to use and apply Taijiquan methods and principles is harder than other styles.
So, if what you are proposing is adding another rung in the ladder so it goes something like:
Stationary Tuishou
Fixed Step Tuisho
Moving Tuisho
Taijiquan Sanda
and then having people logically move into fully open Sanda…
OK. that 4th level is indeed missing and it may indeed be necessary to make the transition from Tuishou to Sanda. However, the limiting factor is the hesitance of the Taijiquan community to even full populate the Moving Tuishou divisions.
To my observation, if a person can’t hang in a fully open stepping moving Tuishou environment where a judge keeps them in contact…the likelihood that they will hang in there for an even rudimentary level of Sanda is slim. While Tuishou is NOT Sanda, it IS where a Taijiquan person is supposed to learn about force, yielding, borrowing, movement, and distance… all of which are core to doing Sanda.
One of the things that has to be avoided is rewarding people for violating rules. I have all too often seen situations where one competitor was NOT doing well following the rules and went beyond them out of frustration. Then their opponent, who WAS following the rules, either gets injured or disqualified because of responding to the first person’s violation of the rules.
Esssentially, in competition, if you can’t follow the stated rules, either get them OFFICIALLY changed…or don’t join in. Anything else is bad sportsmanship and lack of Wude.
