The obvious answer is that the club face is open. An open clubface is a reaction to your swing. 99% of golfers see the pros swing and try to duplicate it. Rotation is the root cause of the open and closed face. More than likely you lift the club in the air and as you swing down to the ball your arms decelerate exactly as your hips are rotating to get out of the way. You'll hear swing the club faster but that won't help because your arms are not moving through the impact area fast enough so when you try to swing the club faster, your hips turn faster. Every good golfer has square hands at impact. Every poor golfer does not. So no matter what swing you have your right hand must be square. What is square? Stick you right hand out as if to shake someone's hand, that's square. Fold the right wrist into the right elbow and stretch out your right arm. You've now compressed the ball.
Just a couple of notes.
01. Your left hand should be strong or rolled to the right at address and your right hand must be weak or rolled to the left.
02. Backswing inside around your waist like Hogan.
03. Downswing below your right knee for depth.
04. Wrist break only on the backswing to fold the wrist back into the right elbow like Hogan.
05. Fold right forearm into right shoulder on backswing like Hogan.
06. Unfold right arm to your right heel not toe.
07. Hips follow. They don't lead. That's why golfers have the slice in the first place by leading with their hips.
08. Swing down with your arms and let your shoulders and hips follow.
09. Try to square your shoulders at impact without rotating your hips.
