A slice can be very frustrating in a game of golf. One tip to fix this is to straighten out the club. When you hit the ball with an open clubface a slice will occur. To prevent this make sure your grip is correct. Hold your club with an interlocking grip then look to see where your thumbs are pointing. They should be pointing down in a straight line towards the club head. If you line your thumbs up and your stance this will improve your swing.
