Resetting the point.

When the fast game has been started at the net, and you feel you aren't winning, then reset the point to get back to neutral.  

Bear in mind that in Noel White's "Pickleball Statistical Analysis" he showed that teams that have the most defensive type of conversion shots lose a majority of their games so don't overuse it.  The key is to stay aggressive and on the offensive because only offensive conversions contribute to winning.
