Good thread as over 90% of golfers "suffer' from slicing.
To slice you have to have an out to in swing path and an open club face.
Sounds simple to fix but in reality it is not because we try to hard ........... that is try to hard to hit the ball hard. And it is a game of opposites. To get the ball up you need to hit down on it, to get the ball to draw you have to aim where the slice finishes etc.
My advice to anyone who doesn't want to take lessons is:
Take a 75% swing and
DO NOT
try to hit the ball hard and
Watch and mimic the Pros. But not Tiger as he is a machine and swings really hard. Watch Adam Scott, or Ernie Els, or Retief Goosen, Phil Mickelson, Vijay etc. They all have easy swings and still hit the ball miles.
Sorry to waffle on.
