This build utilizes immortals and sentries as the main composition of the protoss army. Immortals are very powerful at killing roaches and sentries are good at force fielding the zerg's army into manageable groups. This build is very good at dealing with roach heavy zerg builds which are very popular right now.
This build is a continuation on the basic forge fast expand build v Zerg which can be found here.
20 - Double gas
Chrono Boost two zealots out of your first gateway. Send them straight to your opponent's third base to make sure you are
playing against a standard quick third play.
Get +1 attack and Warp Gate research when you have enough gas. Constantly chrono boost the forge, followed by +1 armor.
30 - Third gas
34 - Robotics facility and three additional gateways
Immediately begin Immortal production when your robotics facility is complete and warp in purely sentries from your gateways.
Drop three more gateways, increasing the count to seven.
When you have two immortals and 8 sentries, move out. chrono Boost a warp prism and rally it after your army. Use warp prism to warp in stalkers or zealots (depending on your opponent's
composition) and attack their third base. You can also use your warp prism to harass your opponent's main or natural base while attacking their third. From here you can either push for the win if the attack went well, if not get out an observer, take a third, continue making units and adjust your composition to what your observer sees.
