We changed some holes this year and made them MUCH tougher driving holes off of the tee. Since it's a tight course people on a couple of tee boxes and greens were always in danger of being hit by tee shots from another hole.
The course owner got the idea of making it OB down those sides of those holes with white stakes. The other side of those fairways were always OB and at the edge of the course property.
It worked to a degree but not completely. It now keeps people from cheating drastically to that side and I've noticed that most people are hitting less club off of the tee when they are just playing by themselves or in a friendly round (as the course owner hoped they would do).
Where it doesn't work is during group money games. Everybody is still hitting the driver and of course there are occasionally stray shots OB in the unwanted direction. One or two players tried the "smart" approach for a couple of weeks but soon figured out that if a whole group of people are going for it, and there is only one winner, somebody will likely pull off the tough shots and have a big leg up on winning the match.
The fact that some will fail and hit it OB doesn't help the "smart" player that made his par and shot a good score...And finished in second place to the one that gambled and pulled of the shots.
Personally I'm still on the fence. If I am really hitting my driver well I take the chance and if I'm not I don't. Over time my average scores would be better when laying up...But that means a lot of second place finishes (which I hate).
