Together with Stork, Flash, and Jaedong, Bisu made up a high-tier quartet called "Taek–Bang–Lee–Ssang", after the players' given names and Stork's nickname "Bang". Showing a relatively low win rate against Stork and Flash (41.67% and 38.46%, respectively, as of June 2011), Bisu achieved a 60% rate against Jaedong. Bisu and Jaedong had a period of tight rivalry against each 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.
