This was a sweet build by Rain in his match against Dear during the Proleague Playoffs (VoD here). Even though he actually lost the match, the build itself is incredibly safe and incredibly strong, and Dear only just BARELY survived twice in a row.

The sentry first followed by double stalker makes Rain safe from practically ALL threats to the point where he doesn't even need to scout until 6:00 (refer to my previous blog post here). While this expansion comes quite late, it comes with a cool window of opportunity, which is a POWERFUL 3-gate aggression that comes at 8:30 and is meant to punish other early expands. The reason the push works is because Rain gets a total of 10 gateway units out (3 sentries/5 stalkers/2 zealots) of his initial 2 gates before even moving out @7:30. The MsC (with an obs) stays home during this attack to deflect any kind of zealot/DT runbys and because you're only on 3 gates, you can afford to continually make probes during the the attack. When I saw this, my jaw dropped (and of course, dropped even further when Dear managed to miraculously defend it). I think this build is super super cool and definitely worth copying into anyone's repertoire of builds.
It's freaking cool! Rain's the man!
Sidenote: the followup 14:00 immortal/chargelot/archon push was in response to Dear taking an early 3rd with colossus and not necessarily part of the build. Again, Dear only BARELY survived this push; it hit with 3 immortals/2 archons/tons of zealots and hit from 2 sides, which would surely kill any lesser player.
EDIT: Puzzle (VoD here)and Myungsik (VoD here) also used variations on this build in the semifinals of Proleague, worth studying!
