Serve to 20

Lay a tarp in the middle of the court.  Servers aim for the zones around the tarp and earn no points for landing on the tarp.  Any system of points could be used.  I have used 2 points for in front of and behind tarp (short and long serves), 1 point for the sides of the tarp, and 4 points for each corner.  First player to 20 points wins.  This is usually run as a serve and shag game for conditioning as well.
