This also related to another question I raised in other thread but haven't received comments yet:
"I believe Yoda mentioned before that closed-closed is recommended for hitter at advance level. Could you tell us why you are using a square open stance. I know it related to the person but is there any guides why someone will use square square, square open etc.. Any advantages on square open?"
Another confusion is: At impact fix, as you mentioned, hands covered left toe which I understand, hands forward and shaft leading, but how can it be middle hands position then? which will have the hands at the back of the clubhead for long irons?
