"Oooooooh! Should I do Tiger style? It looks kick-*** from the stance alone! Maybe the Dragon style because of the name!" Then they proceed do all their practicing (study) and stuff. And then along comes their opponent. No style. No fancy moves. Mr. Fancy Style has his plan of attack all set up. Moves to set up his counter-moves to bait him into the position he wants to get him in and... *BAM!!!* With raw power (along with the technique of delivering a short point-to-point devastating blow) the opponent punches them in the mouth. With that one blow they fall on their butt off-balance because you "don't need the foundation of a proper stance".
"Everybody has a plan. Until they get punched in the mouth." -- Mike Tyson
