Palmer's "High Drops"

This, of course, is a beautiful crazy rally that does not require much comment. However, just look at  David Palmer's drop shot at 0:33 (even if it didn't make him win the rally this time); many players would have gone for the inch-perfect drop just above the tin, but Palmer chooses to play it about 50 cm higher looking rather to make it fade into the side-wall. He does that often, as the drop-shot played as such a high-percentage-shot and not as a clear winner will make the opponent run desperately to retrieve the ball which then generally ends in a stroke or an easy loose ball to put away. I do agree that it's a bit of a conservative thinking with the likes of Ramy and Shabana on the tour, but it's still intelligent and efficient not only in the short term (in order of winning the point) but also in mid-terms (making your opponent spend a lots of energy and showing him that you don't  necessary have to go for winners to beat him), and the longer-terms(increases your unpredictability, the opponent won't know when you will hit a dead drop, or just nudge it a little harder).
