I had the dreaded sh****** for about six months when I was younger. In the end I had a lesson from Sam King (ex Ryder Cup player) who cured me. (well - you never get cured completely!)

He reckoned that there are two types of sh***** The first is the most common and happens on short irons eg pitching wedge to the green. The problem is not turning and bringing the club down outside the line.

The second he termed the "professional sh****" and this can happen on all your shots. The sh**** is caused purely by swinging the club through too far awy from you, so that the heel of the club makes contact rather than the centre. Sam said that many pros address the ball with the toe of the iron to avoid this problem. The "cure" was to try to swing the club through on the inside of the ball. Sounds simple but it worked for me.
