Hitting the ball fat!!!

Question
I've been playing for about 6 months, I've improved alot,but know I'm hitting the ball very fat. I need some practice techniques to cure this and suggestions as to why this is happening. I believe that it is from my knees bending but not sure. Any suggestions would be great!! Thanks

Answer
hello roger.  thank you very much for your question.  if you are hitting the ball fat, there are many things that could have gone with your swing.  unfortuantely, i cannot view your swing and i cannot spot the cause for you to hit the ball fat.  however, these are some common reasons as to why you are hitting the ball fat.  
1.  there is too much dipping motion througout your swing.  by that, i mean that your body is moving up and down as you swing the club.  instead, it should be straight back and through.  to fix this...  you should practice "standing tall"  stand tall at the point of your adress and as you swing, resist the temptation to hit the ball.  instead, just swing your club without thinking much about the ball.  because you are trying to HIT it, you are catching the ball fat.  don't do try to HIT. instead, just swing..  like you take your practice swings.  doesn't your practice swing feel nice? and doesn't it seem to just brush the grass as you take a practice swing?  that is because you are not concerened about hitting the ball.  instead, you are just swininging.  do this same concept when you are actually hitting the ball.  does that make sense?  hit the ball just like you would be taking a practice stroke.
2.  don't dip your right shoulder.  one simple reason why you are hitting the ball fat is because you are dipping your right shoulder as you are hitting the ball.  just check for your right shoulder and make sure it doesn't dip as you swing.  
i hope i was able to offer some help to your swing.  with the given information, this is the best that i can do for you as of right now.  and also.. about the bending of your knees...  i personally do not think that your problem is your knees.  i have never encounterered with a student who was catching the ball fat because of his/her knees.  have some fun and if you have ANY questions about this game, let me know and i will do my best to help you.  good luck.
