Last time, Gade had a hair cut in late 2006... Guess what? He won 2 tournaments... Cop. Masters + MO 07 Your little theory does not hold true.
Yes, he won MO but had a string of horrible losses after that, so conclusion its still better to keep yr original hair style And also nvr ever change yr hairstyle b4 a big tournament like WC, OG...
Now that I think about it again... I had a haircut 1 week before my last team tournament... that must have been why I lost in that tournament. Wait a second, it was our last single player that lost the final match though... So, now I have two legitimate excuses... 1. my haircut 2. my teammate's loss
