other, competing for the top place of the KeSPA rankings: during the 2008-2009 Shinhan Proleague season both players finished the 4th round with a total tally of 44 wins, while their individual league wins equaled to three at certain point. On par with Stork, Bisu established what is occasionally called the "Taek–Bang era" of professional StarCraft. However, as opposed to Stork, Bisu's OSL title has been elusive. After competing in three OSL qualifiers in 2006–2007 Bisu unsuccessfully pursued the OSL titles of 2008, 2009 and 2010. Nonetheless, as of June, 2011, Bisu collected five Monthly MVP titles, equaling that achievement with Flash, Jaedong and SlayerS_`BoxeR`. On June 7, 2011, having defeated Protoss player Flying, Bisu equaled Flash's record of 57 victories in a StarCraft Proleague season. In addition Bisu managed to advance to the main group stage of the MSL tournament 11 times in a row, approaching sAviOr's record of 13. He also scored the unprecedented result of four all-kills (a form of StarCraft competitions, where one team is eliminated by a single player of the other team). In 2010 Bisu was nominated by Fomos for the title of Player of the Year and Protoss of the Year. After the transition to StarCraft II, Bisu rarely played for his team SK Telecom T1, accumulating a 12–16 record and eventually announced his retirement on September 9, 2013 Bisu's game performance, as well as that of Protoss in general, has been influenced by maps on which the StarCraft matches are played. Although StarCraft is considered a balanced game in that all three races have successful professional players, the maps differ from each other in properties such as the terrain openness. One thing Bisu did during practice was to take notes, so he wouldn't forget what he practiced and learned. Playing style Like other Protoss players, Bisu generally starts the games with commencing a second base, Corsair harass when confronting Zerg and subsequent attack of mixed units, including High Templars. Conducting a relentless harassment, often using Probe scouts and known for superlative multitasking, Bisu widely used Corsairs to gain air superiority and Dark Templar assaults against Zerg. Bisu's harassment style and the use of Shuttles were praised particularly by Stork. Bisu popularized the associated opening against Zerg, which has been called the "Bisu build": a Protoss player in such opening would warp in a Forge, skipping weapon upgrades, and having warped in a
