How do i keep the club face closed on my golf swing?

QUESTION:
I seemed to have developed a slice on my golf swing and can’t sort it out. I think i’ve got it down to opening the club face on my down swing. Has anyone got any ideas how to solve this?

First you should check your swing plane. This is kind of difficult to tell all by yourself so have someone watch or video tape your swing. This is one big reason why the club face is open at impact.

Also check your grip. A weak grip has your thumbs at 12:00 while a strong grip has your thumbs a little further back 1 or 2 o’clock. The strong grip will help in closing the club face through impact.
