Tcc theory doesn't say that tcc is soft. It says things like "when I am soft and the opponent is hard, it's called yielding." But, that's a description of not depending on force to oppose force. Or, there's the concept of 'the needle wrapped in cotton."
Softness can't mean that the punches hit softly. Ok, there'll be those who say that the power for the punch is generated differently, but that's a different subject. There are also those who'll say that a tcc is like the five fingers of death touch, and that the effect of the 'punch' doesn't come from it's power. But, that's too dangerous to discuss here
. So, I'm talking about the ordinary 'hard' force that will knock someone out.
Anyway, my coach said that you're supposed to hit hard and the other guy has to figure it out. You don't even need to worry if it's tcc. OTOH, if the other guy is stronger and faster, then you need to use tcc.
