This sport worked its way into my system due to the years spent in CA at the beach. The Block-It Scientists team captains for 2008 are Shelly Berger and myself. Links to photos are given below. Some important play strategies for beach volleyball are to recognize the court is small 8 by 8 meters versus 9 by 9 for indoor volleyball. This means ball placement is more critical and one has to be careful that deep shots and serves do not go out. Some other pointers include: (1) Service, try for 4/5 good serves, (2) Passing and Setting, low energy but try to get the ball ~12 ft above the ground, i.e. try to "absorb" the energy from the serve/hit, (3) Dig, use the flat part of your fist - leave all your energy on the court, (4) Two Hands, God gave you two hands for a reason, limit one handed passes.
Links to each person's photo are given below with the roster list. Block-It Scientists 2008: Barry Walker F, Shelly Berger UG, Matt DeCamp F, Liz Van Wie UG, Ismat Shah F, Bindiya Arora G, Sam White UG, Rob Sauer UG, Heather Crandall UG.
Sample game positions are given below. Note best options are the arrows, gray areas are the backup plan if a pass or hit is slightly off.

After serve, receiving serve is the most important play. The primary setter covers only the region in their immediate vicinity - their primary focus is to prepare to get the pass and setup the play. The secondary setter covers that weak spot right in the center while the passers will take 90% of the serves.

The standard play for receiving is simple. First touch passers get most of the court, setters handle only the dinks. Next play is to the open setter, who sets up the play to the hitter.

Movement is what distinguishes experienced players. They follow the ball while on the opponents side, anticipating the hit locations. Simple examples are given here, notice how players move to adjust coverage given the most likely hits. Communication is also important so the right person goes after any dinks the hitter might try.
