To cure your slice and hit it solid, practice with a four-knuckle grip

Golf Digest, July, 2002 by Scott Davenport

We're often told to swing "from the inside out" rather than "from the outside in" to avoid a slice. But that advice can be misleading. Many good players have a slightly out-to-in swing path. David Duval and Bruce Lietzke are good examples. But there is one thing all good ball-strikers do: They "drop the club in." That is, they bring their right elbow into their hip halfway into the downswing, so the club is positioned as you see here.

A good drill to learn this move is to take a superstrong four-knuckle grip (far right). The flap on the back of your glove should point to the sky, so you can see all four knuckles of your gloved hand. Now try to hit straight shots.

The only way to do that is to drop the club in on the downswing and have your hands lead the clubhead at impact--two keys to powerful, straight shots. Make the same move with a more neutral grip, and watch the ball fly.
