Great example of Beth at the Wirral 15K this week using the wide serve (always a strength for the lefty!) and then making the smart decision to go back behind her opponent with ball 3. This was smart because her opponent played a slow return which allowed her to reposition relatively well. Had the return been hit with more pace and therefore limiting her opponent's recovery time, Beth (I hope!) would have taken ball 3 into the open space using the double opener! I wonder where Beth goes with ball 5??!!
Simple rules (clear plans/patterns) can be helpful as they reduce uncertainty/anxiety and increase confidence, so when serving wide go back behind your opponent when the return is slow, and into the open court when its faster and build the point from there! Of course there will be exceptions but follow the rule first and then explore the except ifs.
