If anyone who is interested in golf plans to get mentored on how to play the game, he has to understand that errors must not be left out as it is one way to correct a beginner. A hook is a mis-hit and really needs to get adjusted so as not to make the same boo-boo again which can mar the whole game of a promising player like you. Every player has to take into consideration that it is not all the time that you commit a mistake while playing and not all the time you can play a perfect game. Blunders, if adjusted earlier, can make you deliver a good performance. You should remember that great players have undergone this situation before and have played erratically like you did, but with some amendments, they managed to enhance their playing style and things had never been the same again.
In order to fix a hook, one must tackle on three things and that would include impact, the grip, and the stance. With all efforts coming from the player, armed with the proper tools and guidance from books, videos, and right coaching, fixing this type of blunder is not a far-fetched idea. If you can only look closely, you will see where you fall short on the game and subsequently, a not so good game can be corrected. Having a mind that is open for possibilities can surely beat the hell out of every game.
If you see a ball hooking towards the left, there is a possibility that it would curve with a right to left motion in the sky. The ball would spin on a counter-clockwise course. To counter this, make an effort to spin it the other way around so that the club swing must be more going to the right using the club face slightly pointing towards the left. Check on your divot's direction to be sure. To achieve that classic hook, the divot must be pointing to the right with your ball ending well on the left side of the direction of the divot.
The grip does not have much to do with the swing direction but only focused on the club face and how it looks when the club comes in contact with the ball. Not all grips can do well for every player as every shot can be considered unique and its effect will all depend on how the player himself plays the game, or handles the club while at ball address. Position the club face square on to the target so that you can ably look down to see just your two left knuckles; seeing more would mean you are up for a hook. Another thing that can fix a hook is by looking at the v-formations formed by the knuckles and thumb on your hands while gripping the club. They should somewhat point just beside the right shoulder and ear.
Double check on your stance and grip so as to eradicate any hook possibilities without having to change the hitting gesture. Observe the ball's flight and let it be your guide; by doing so, you will be able to see how the ball took the impact and definitely you would know where it will end up. So, if ever you see that your ball ring lesser to the left than what you had been doing before, are well on your way of becoming a corrected player, meaning-you already know how to fix a hook.
