So yes, it is an appeal to majority, and it is perfectly valid!
lol
The majority of YM students didn't learn the free fighting aspect of VT.
---Again, were you there?
Don't need to have been. Just look at what they teach.
And a Tan Da does not use two arms against one. It uses one arm against one while the other arm is striking through the opening created.
That's two arms to deal the opponent's one punch when one arm could do the same.
But I've got news for you.....more appeal to majority here.....both Pin Sun Wing Chun and Tang Yik Weng Chun have a Tan Da and consider it simultaneous attack and defense! So just maybe the complete understanding of the concept is actually lost on you!
That is simultaneous, but it's not a particularly special skill to develop. LSDD is referring to something more developed and unique to VT fighting tactics.
---John never said he didn't learn to do that. He only said he has a wider understanding of how the concept can be applied than you do!
No. It's very clear he has never heard of it and has no idea how it might work.
