EffOrt's career as a Brood War progamer started relatively late, as he played his first televised match in 2008. He was dubbed the "neo-sAviOr" at that time due to his playstyle’s strong resemblance to sAviOr's. EffOrt went up the ladder in his team, and became the most frequently used Ace player by CJ Entus. He realised his first major achievements in individual leagues in the summer 2009, as he took the third place of the 2009 GOM Classic Season 3, won the BlizzCon 2009, and reached the quarterfinals of the 2009 Avalon MSL. His coronation in OSL occurred in 2010, when he defeated the heavily favorite Flash in the grand finals of the 2010 Korean Air OSL, in a tied series that he won 3-2 after a 0-2 deficit. He announced his retirement in September 2010, only to come back in March 2011.
