my interpretation of 'split' is when you use opposing forces, like push and pull, simultaneously.
a good example would be the use of single whip, where you 'hook' the incomming punch, and pull it in, continuing the force towards you, while striking out towards the person with the other hand; thus increasing the effect of the strike.
(sorry i didn't explain it better, hopefully you understand what i mean.)
... ok to clarify; i use single whip exactly as hsing-i's pi-chuan ("metal"/splitting) ... if you are familiar with that.
another example would be when you use 'strum the lute' to hyperextend the elbow.
one hand applies pressure to the opponents wrist in one direction, and the other hand applies pressure to the attackers elbow in the other direction. - opposing forces.
someone please correct me if i am wrong.
The more you know the less you need to show.
May you be filled with loving kindness.
May you be well.
May you be peaceful and at ease.
May you be happy.
