1. Slicing is caused by an open club face.. an open stance.. and a weak grip. Lets look at your grip first... Hold the club in the fingers.. not the palm. Be sure there is no gaps between your thumb and index finger of either hand and the "V" created by your thumb and index should point directly to your left shoulder. When you address the ball you should see 2 1/2 to 3 of the knuckles on your right hand if your gripping the club properly. This will feel strange to you if your grip is usually in a weak position.... the "V" 's are pointing to your chin or right shoulder. Gripping the club properly will enable you to square the face properly       2. Next check your alignment.  With a ball on the ground or a tee take your address position, then simply lay the club down on the ground so its touching both feet. Walk behind the club after you place it down to see where your aligned. If your alignment is too far right your stance is open. This will induce a slice. If your alignment is off, when practicing stand from behind the target your hitting to, lay 1 club down pointing directly at target, lay another one down in front of it leaving you just enough distance for your feet to fit in. Hit several balls from this position, take the clubs off the ground after 15-20 shots and address the target without them, then lay the club down and walk behind to check your alignment. You should notice a change. You can't do this on the course but you can pick a spot  from 1 to 3 feet in front of the ball... when you address it visualize a line from the ball to the spot. Stand parallel to this line.    3. The over the top move.. If your slicing there is a good chance your coming over the top. If your divots point right of the target consistantly then you are coming over it. When you practice you'll need an empty plastic drink bottle. Lay this bottle down on the left side of the ball parallel to the target line about 3 inches away with the cap end in front and even with the ball. Now hit balls like this without hitting the bottle. If you do hit it, it won't hurt you or your club. I would use a 6 or 7 iron to start with. After you get the hang of this you should notice your divots pointing to the target or slightly left of it. I'm a 2 handicap golfer, I have used this method with several people with good success.. You have to be practice at least 3 times a week doing these 3 things.. Good grip, good alignment, proper swing path. If you do this 3 times a week for 1-2 months for just 20-30 minutes per session I guarantee you'll lose that slice. Be sure when hitting balls the first several times to swing at no more than 50%. Gradually build your way up. If your slice comes back slow down a little. Everyone is different, my best results come when I swing at 70%, yours may be more or less. See you in the middle of the fairway and the middle of the green!!

great advice, great tips the only thing i saw missing was the swing plane its self.  you hit all the age old ident ifiers. but i used to hit a power fade back in the day  and if it was a bad swing it was a slice. looked at video and discovered it was be couse i had an out side to in swing. thats also a major problem. my stance was good my grip was good i was just pushing the club outside from the the top of the down swing witch if your pushing it out at the top your probably not going to correct it by the time you get to the bottom. so you've seen all the whats in my bag clips on the golf chanel right. notice how all of them have the alignment sticks. great great investment. if you stick one in the gournd angled at the right degree you will see where your club needs to enter the swing plane. take all the tips above for aligne ment especialy the 1-3 foot refrence mark that is the easyist and best way to get your self on line every swing. second is slow down the back swing make sure your in the right position at the top of your back swing. keep a loose grip.  swing easy. think of pulling the club in the begining insted of pushing it. this will help get on the right swing plane.  but best advice is to get some lessons from your local pro.  this is a sport you can play your whole life so why not invest in lessons.
