Both players opened with standard builds in cross positions on Frost. Classic then chose a robotics facility as his primary tech, going all the way up to robotics bay for warp prism speed and disruptor drops. soO's overlord speed investment paid off, however, as he saw the bay building. This gave him all the freedom in the world to continue droning heavily while waiting for his lair to finish. soO took little damage from Classic's disruptors. When Classic finally moved across the map for his 2-base all-in with glaive adepts, soO dropped lings in his opponent's base. Despite losing his own third base, soO came out ahead in the trade, killing 22 probes and destroying Classic's disruptors and warp prism. One last desperation push from Classic did next to nothing and he was eventually forced out of the game when mutalisks appeared.
Proxima Station saw Classic get more aggressive, opening double gas off one base and hiding a stargate on the map. He was able to kill six drones while forcing a lot of zerglings out through an adept & mothership core poke at the front. At the end of the day, though, soO still found himself on three bases against Classic's only just building natural nexus. Classic again tried a two base all-in with glaives, but soO defended it easily, while zergling drops continued to keep Classic busy at home. Classic must have felt he had little choice but to expand and go again with more adepts and sentries, but soO once again shut him down easily. A simple bane/hydra counterattack sealed a second victory for soO.
The pattern of the series stayed the same on Whirlwind, with Classic opening with an offensive double gateway pressure build into expansion. A stargate and glaives felt similarly ineffective to the previous two games, but Classic at least kept soO on his toes and making units. When he finally hit his three base attack with adepts, sentries and an immortal, he hit just before soO's first hydras came out. A first set of forcefields looked perfect, but left Classic without sentry energy. soO's banelings came crashing into his army and obliterated all his sentries and most of the adepts. The warp prism was shot out of the sky by queens and so were Classic's hopes of winning his first game in the series. A simple counterattack put soO at 3-0.
Newkirk Precinct, unsurprisingly, saw Classic attempt a two-base all-in with charge and immortals, but soO's overlord speed again gave him all the information he needed. When Classic moved out, soO dropped zerglings in his main for what felt like the hundredth time in the series. Classic's aggressive zealot warpins meant that he had no defense at home. soO defended the hugely weakened all-in easily and clinched the 4-0 sweep.
soO therefore moves on to his 6th GSL Grand Finals where he will face GuMiho, guaranteeing that a new GSL Champion will be crowned on June 24th.
