Too often players worry about their stroke techniques while playing a match. The end result is they try to consciously control their shots. The more they try to do this, the worse the shot gets; and the worse the shot gets, the more they try to consciously control the shot. The end result is disaster! Instead, think of only two things in a match. First, think about tactics – how you will use your shots. The shots themselves will take care of themselves – or at least will do better on their own if you let them go then if you try to consciously control them and make too many "fixes" in mid-match. Second, if a shot feels wrong, then the way to fix it during a match isn't to try to over-analyze it. Instead, think about the feel of the shot, and try to get the right feel. Save the stroke analysis for after the match – it rarely helps during a match.
