cut an attacking force in half
temporarily and recall can
eliminate the need for shuttles.
Its permenant cloaking field also
provides a problem for the oppenent.

    Shuttle
The protoss shuttle is the
fastest of the flying transports
and can be made the fastest
putting the protoss at a further
advantage on an island map.
 

                                                    Protoss Build Orders

Protoss Island Build order-This is the build order I use at it pretty much guarentees victory against any zerg player and any terran player on isles only problem is against another protoss player which would mean that it will be a race between who can get shuttles the fastest.
1.  Send all 4 drones to harvest at different mineral patches.
2.  Build drones up to 7 and while the 8th probe is halfway done build a pylon.
3.  If you have done everything correctly so far as soon as the pylon finishes your 9th probe should be done and you should have enough minerals to build a gateway.  At this time build a gateway.
4.  continue building probes until gateway finishes and as soon as gateway finishes build a cybernetics core.
5.  While cybernetics core builds build an assimilator and a forge.
6.  When cybernetics core finishes build citadel of adun.
7.  Build a templar archives and a robotics facility.
8.  Build pylons as needed and surround your nexus with about 4 photon cannons.
9.  When robotics facility finishes build a shuttle and robotics support bay.
10.When templar archives finishes build a templar research psionic storm.
11.Now begin to expand and when you expand build pylons and photon cannons around your island expansion before building the nexus once you feel the island is secure build the nexus.
12.From here its up to you and your attack squads should consist of a few scouts reavers in shuttles templras in shuttles and archons in shuttles.

Zealot Rush-Can be effective but I dont use this one often.
1.  Send all 4 tProbes to gather minerals at separate patches. Warp in three more Probes at the Nexus, assigning them  to mineral patches as they are produced. With the third Probe (7/9)warp in a Pylon, then order it to gather minerals.  From this point on, always have one Probe (and only one) warping in at the Nexus. As soon as the Pylon is finished, you should be working on your ninth Probe. Start a Gateway the instant you have 150 minerals.
2.  Begin a second Gateway as soon as you have the resources.  Whenever a Probe is produced, order it to gather minerals from a patch that has yet to be mined. If there are no free mineral patches, double the Probes up. Remember to continually create Probes until you have 15 or so). then the first Gateway is complete, begin warping a Zealot. Do the same for the second Gateway.  Before warping in a second Zealot from the first Gateway, create a second Pylon. Use that Probe to scout out the location of your opponent.
3.  Continue warping Zealots in from your Gateways, but be sure to have only one unit cued up at each facility. The goal here is to maximize the rate of production. When you have 150 minerals on hand and both Gateways are working on a Zealot, begin a third Gateway. Remember to make Pylons when the Psi Counter is at least two less than its maximum.  Once you've acquired six to eight Zealots, attack! If you wait too long, your opponent will have had time to prepare. If you attack with too few, you'll be beaten back. With your scouting Probe decide which opponent is the most vulnerable to a rush and nail him! Continue cranking out Zealots from your three Gateways. When making the initial attack, try to rush past any prepared defenses and  take out the workers; although you might loose your initial assault team, you'll have crippled his economy. The key is not to let up! Keep pounding them back with Zealots. If you're not gradually gaining an edge, however, you're better off to cancel the rush and try to start climbing the tech tree to reavers and dragoons.
