Alan, good luck tommorrow. Here are some simple things to remember(note: I am 60 yrs. old but shoot to a 3)
1. when in doubt, take one more club and swing smoother
2. slow backswing and watch ball position, esp. driver
3. if you tend to slice, close your stance, play the ball a little bit more towards center than usual, and get that good shoulder turn
4. On downswing, lead the ds with the butt end of the club-the clubhead always comes last in the sequence.
5. chipping-play the ball back further than you have been and hit down to make the ball go up-choke up on the club for shorter distances.
