Now you need to show what you mean about not having to defend the gates against any opponent ever. How is this achieved? Text does not convey your message because there are a million "What ifs" in regards to your text.
I said "4 gates", as in facing your opponent with a man/wu guard holding center.
That is already a strategy that spreads you too thin and leads to tactics like taan-da.
So far what you write sounds very close to: "if you do as I do you will never ever get hit!" which we all know is (Bah:censorship) 'not true' and that cant be what you mean.
Of course it isn't. Like a water fight, both parties are bound to get wet, but it's about increasing percentages in our favor to come away drier than the other guy.
