Young Thirties vs. Ohapjijon | Match 1 D-Tier Dopungreumaenggo | Sopungni(P) 2 : 0 Suryeonsuryeon(Z) | Ohapjijon

In Game 1 of Set 1, Suryeonsuryeon opened with a 12 Hatchery, while Sopungni opened with a Forge Double Nexus. Suryeonsuryeon applied pressure with a small group of Hydralisks while preparing Lurkers. In response, Sopungni inflicted damage with a Dark Templar drop. Suryeonsuryeon also attempted a Lurker drop, but it dealt little damage. Fitting for D-tier play, it was far from a conventional game. Neither side launched full-scale attacks, opting only for minor harassments, and Suryeonsuryeon immediately rushed to Ultralisks. However, there was no movement. Despite having a large army, the units sat idle in front of the natural expansion, allowing Sopungni to lead her entire ground army to squeeze the Zerg entrance, win consecutive fights, expand her bases, and take Game 1. In Game 2, Sopungni went for a Photon Cannon rush, but failed due to a misplaced Pylon. However, even though the Zerg defended easily, Suryeonsuryeon overproduced Zergling units. Suryeonsuryeon produced mass Hydralisks without upgrading to a Lair. Sopungni easily held it off with multiple Cannons and solidified her lead by killing numerous Drones with High Templar harass. Suryeonsuryeon then attempted a massive Hydralisk bomb drop. Although she destroyed a fair number of structures, the attack was contained, leaving the Protoss firmly in control. While repeated drops inflicted decent damage, it was not enough to spark a comeback, and Sopungni won Game 2 as well, defeating Suryeonsuryeon 2-0.

Dopungreumaenggo vs. Ohapjijon | Match 1 C-Tier Dopungreumaenggo | Runner(P) 1 : 1 Neaklet(Z) | Ohapjijon

In Set 2, Neaklet started at a disadvantage in Game 1 after making a major blunder by placing his natural Hatchery too far away. Opting for a Hydralisk all-in, Neaklet timed his attack perfectly when Runner's Zealots moved out, claiming victory in Game 1 of Set 2. In Game 2, Neaklet went for a fast Lair after his natural expansion, followed by a Spire to prepare Mutalisk harassment. Runner started with a standard Fast Expansion (Double Nexus) and built Cannons in both his main and natural base to prepare for Mutalisks. Runner successfully defended against the Mutalisks with multiple Cannons and Corsairs. Runner was clearly in a favorable position, as Neaklet's additional expansion was delayed considerably. However, both players gave each other plenty of time, pushing the match into the late game; Zerg managed to produce Ultralisks, while Protoss maxed out at 200 supply with ground forces. Seizing an opportunity by pushing back Ultralisks in the center, Runner pulled his forces back right when he had a timing to end the game. Nevertheless, after regrouping briefly and mounting an assault, Runner won Game 2 to tie Neaklet 1-1.

Dopungreumaenggo vs. Ohapjijon | Match 1 B-Tier Dopungreumaenggo | Gosudal(T) 0 : 2 Captain Jack(P) | Ohapjijon

In Set 3, Protoss player Captain Jack opted for a direct Double Nexus, while Terran player Gosudal opened with a Barracks Double. Looking strictly at the builds, the momentum favored Protoss. Gosudal made a high-stakes gamble by building a hidden Command Center at the 5 o'clock expansion early on. However, Captain Jack launched a surprise 3-Zealot pressure, bypassing the Bunker and charging right into the opponent's main base to inflict severe damage, locking down the upper hand. Gosudal held out, relying on his hidden expansion, but Captain Jack discovered and destroyed the hidden base with Zealots before effectively taking trades with his overwhelming army. Unable to overcome the massive gap, Gosudal surrendered Game 1 to Captain Jack. In Game 2, Captain Jack went for a Double Nexus once again. Gosudal chose to match the expansion, but spent extra resources building a Bunker and meticulous Turrets, falling further behind. Gosudal instead took a slow Triple Command Center. This was a solid decision. Captain Jack added multiple Gateways after his third base and attempted an attack, but was held off by the entrenched Terran forces, making the game very playable for Terran. Although Protoss took terrible engagements, Captain Jack led in production capability and managed to defend using Arbiters, regaining the upper hand. While Terran consistently got favorable trades in combat, Captain Jack took control of Terran's main base with an Arbiter Recall. Ultimately, Captain Jack took the victory, securing a 2-0 sweep against Gosudal.

Dopungreumaenggo vs. Ohapjijon | Match 1 A-Tier Dopungreumaenggo | Dopa(P) 2 : 0 Ambition(T) | Ohapjijon

The final A-tier battle between Dopa and Ambition was a crucial game where Dopa needed a 2-0 sweep, while Ambition needed only a 1-1 result to lock in a ticket to COEX. In Game 1, both players had standard openings with Factory Double and Dragoon Double. Knowing Ambition favors early pressure, Dopa built a 2nd Gateway before his Robotics Facility to defend against early aggressive moves, smoothly taking a third base afterward. Ambition prepared a 5-Factory timing rush. However, Dopa also secured multiple Gateways after his third base. Advancing to the center, the Terran player set up position and built a Command Center at 3 o'clock rather than overextending. When his Zealot speed upgrade finished, Dopa decisively broke through Terran's containment line to take the win. In Game 2, Dopa built a proxy Gateway near the opponent's natural base and harassed with Zealots. Ambition tried to hold off the Zealots using SimCity and Marine micro, but sustained heavy damage. He managed to construct a Factory and produce Siege Tanks, but Protoss Dragoons had already overrun the Terran main base. Dopa took a 2-0 victory against Ambition, securing Dopungreumaenggo's advancement to the COEX event on Sunday.

Young Thirties vs. ACDC | Match 2 D-Tier Young Thirties | Ssangbe(T) 1 : 1 Inganjelly(Z) | ACDC

In the D-tier match between Young Thirties and ACDC featuring Ssangbe and Inganjelly, Inganjelly went for a fast Zergling attack, while Ssangbe defended by constructing a Bunker at his natural entrance. Ssangbe then built 2 Factories after expanding to his natural base before late-adding Bionic forces. In response, Inganjelly prepared a Zergling and Lurker attack, breaching the defensive line that lacked Siege Tanks to claim victory. In Game 2, Inganjelly once again went for early Zerglings, but made a blunder by delaying an Overlord. Nevertheless, he greedily expanded to the 9 o'clock base shortly after, while Ssangbe produced Goliaths off 2 Factories as in the previous game. Ssangbe belatedly added Bionic forces to assemble a doom stack. Just as Terran began to move out, Inganjelly launched a counterattack into Terran's base, completely throwing off Terran's timing. However, Ssangbe pushed out again and dealt heavy damage to Zerg's natural expansion, securing the win to make it 1-1.

Young Thirties vs. ACDC | Match 2 C-Tier Young Thirties | SoUroop(T) 0 : 2 DDaHyoNi(P) | ACDC

DDaHyoNi prioritized tech over a natural expansion to prepare a Dark Templar drop. SoUroop spotted the Templar Archives with SCV scouting and built Vulture Mines and Missile Turrets. Although the setup to hold easily was in place, the Dark Templar dropped from a Shuttle destroyed the Turrets and inflicted significant damage, handing the initiative over to Protoss. DDaHyoNi continuously harassed the 9 o'clock expansion while expanding his own bases and teching to Arbiters. Already maxed out at 200 supply with 3,000 to 4,000 unspent minerals/gas, he virtually sealed the win and even showed off with Arbiter Hallucinations before taking the first game. In the next game, DDaHyoNi went for a Double Nexus followed by a fast Forge for Cannon defense. Seeing the early expansion and Cannons, SoUroop attempted a 2-Factory containment push, while DDaHyoNi again prepared a Dark Templar drop. Terran destroyed the natural Nexus through the containment, but the Dark Templar drop devastated Terran's main base. Terran set up position at Protoss's natural expansion in a standoff, but Protoss was essentially in complete control. However, the game dragged on. Even as Protoss accumulated Carriers and Terran produced only Turrets, it felt as though Protoss was intentionally delaying the win to toy with his opponent. DDaHyoNi took over the 7 o'clock main and natural expansion originally owned by SoUroop, dominating in resources to seal the win.

Young Thirties vs. ACDC | Match 2 B-Tier Young Thirties | JungRyungWang(P) 0 : 2 Flame(Z) | ACDC

The B-tier showdown between JungRyungWang and Flame ended in a 2-0 sweep for Flame. Game 1 finished quickly. JungRyungWang, who attempted a Double Nexus, built only a single Photon Cannon to maximize greed, but Flame capitalized with a fast Speedling assault that broke through JungRyungWang's defense line for the win. In Game 2, JungRyungWang built two Cannons safely after a Double Nexus to prepare for the late game. Flame also opened with Spawning Pool before expanding, focusing on Drone production before building a Spire for Mutalisks. JungRyungWang rushed upgraded range Dragoons before Templar Archives to launch an attack. Flame hastily built Sunken Colonies and successfully held with mass Zerglings. The match then stretched into a long game. Flame reached Hive tech to produce Defilers and Guardians, while JungRyungWang accumulated Archons and High Templars and secured plenty of resources by taking the 5 o'clock natural expansion. Despite having his natural gas mining disrupted by Guardians, JungRyungWang suddenly built multiple Stargates at 5 o'clock. Flame struck Protoss's main base and expansion simultaneously with Defilers and ground units, while JungRyungWang produced Carriers out of his Stargates. However, the Carriers made little impact, and continuous waves of Zerg forces overwhelmed Protoss, giving Flame the 2-0 victory.

Young Thirties vs. ACDC | Match 2 A-Tier Young Thirties | Crank(P) 1 : 1 AGU(P) | ACDC

In the final A-tier match, while the overall match score was already heavily tilted in ACDC's favor, Crank needed a win in the A-tier duel to boost his team's morale. On Fighting Spirit, Crank ended Game 1 early with a Power Dragoon build against AGU, who had opened with a 2-Gateway Robotics Facility build. In the following game on Eclipse, Crank opted for a 3-Gateway Dragoon build without a Robotics Facility, while AGU built a Citadel of Adun off 2 Gateways, aiming for Dark Templars. AGU defended at the ramp while waiting for Dark Templars. Even after the Templar Archives finished, Crank still had no Robotics Facility. Ultimately, as soon as the enemy Dark Templar spawned, Crank called a quick GG, giving AGU the win.
