[1][2][3] Park, who also goes by the usernames Six_Devil_nO.1, ChoGoSy or TechniCal, is recognized as one of the best Protoss players in the world, an accomplishment for which he has been nicknamed "Hero Toss".

He is skillful at macromanagement and does successful psionic storms and dragoon dancing, but plays relatively inconsistently against Zerg.

[citation needed] He won the 2002 Sky Ongamenet StarLeague, beating SlayerS `BoxeR` with a 3–1 score.

[citation needed] Park was the first player to achieve 100 Proleague victories, an accomplishment commemorated when he and Lee Jaedong (the second player to reach that benchmark) formed prints of their mouse-controlling hands in clay in a September 2009 ceremony.

[4] Park is now a coach for League of Legends and Tekken team NaJin e-mFire in Korea.
