The semifinal matches in GSL Code S are set after a two-day quarterfinal blitz. Reigning champion Dark moves on to defend his title with a fearsome Jin Air trio of Maru, Trap, and Rogue looking to seize his throne. The Code S semifinals will begin Dark vs Rogue on Wednesday, Sep 18 9:30am GMT (GMT+00:00), followed by Maru vs Trap on Saturday, Sep 21 4:00am GMT (GMT+00:00)
Those looking to Dark vs TY for insight into BL-Infestor in TvZ would have been sorely disappointed, with Dark willing to make every Zerg unit except Brood Lords. Dark explained in his post-match interview that after showcasing so much BL-Infestor play in his ZvT-packed Ro16 group, he wanted to circumvent whatever counters that TY had prepared. Dark may have regretted this decision on the occasions when his ground-based armies charged headlong into TY's Terran meat-grinder, but he was still able to escape with a narrow 3-2 victory.
Trap earned the only 3-0 sweep of the quarterfinal round against KeeN; a harsh send-off to the veteran Terran playing in his final match before beginning mandatory military service. Trap put on a macro-play clinic, deflecting KeeN's early attacks (including a stroke of luck against a clever 'proxy' factory) and comfortably powering up to defeat him in the mid-late game.
Rogue finally overcame his Code S quarterfinal jinx, advancing for the first time in nine attempts. However, his series against Zest was anything but clean, giving up a map after a failed bane-ling all-in, and then throwing an all-but-won game after shutting down Zest's hidden Stargates. However, Zest's counter-throw in game five was enough to hand Rogue the series, with an ineffectual cannon-rush sealing a 3-2 victory for Rogue.
Despite losing 1-3 to Maru, RagnaroK proved to be more resilient than many would have expected headed into the match. He scored the first point of the series by crushing Maru's Battlecruiser mech with an incisive Corruptor-Ravager attack, and stayed surprisingly even with Maru in game two before running out of steam in the late game. Unfortunately for RagnaroK, the next two games were a Maru skills showcase—Ghosts neutralized RagnaroK's BL-Infestor in game three, while a non-stop barrage of bio attacks and drops pummeled RagnaroK into submission in game four.
