Hong, nicknamed the "Storm Zerg" and "Kong Jin-ho", is known for his aggressive and harass-style play, and for his rivalry with BoxeR. He is famous for never having won first place in major StarCraft tournaments despite his strong performances. Hong managed to finish second place six times in events which earned him the title "King of Silver". While there are some tournaments in which he finished first, these records were invalidated when the KeSPA announced that it would accept only OnGameNet Starleague and MSL records. His notable victories include first place in the 2003 ITV 5th Starleague, the Snickers All-Star league in 2005, and the first BlizzCon invitational tournament. Hong suffered his last major defeat against Han "Casy" Dong-wook in the semi-finals of the Shinhan BankSeason 1 OSL in 2006, and claimed 3rd place. Due to his poor performance in the following OSL, Hong has fallen into a slump from which he has not recovered. Hong reached the round of 32 in the GOMTV Averatech Classic, but was eliminated by oDin. He enlisted in the Korean Air Force in November 2008 in the StarCraft team Air Force ACE. Starleague After being a member of ROKAF ACE, Hong recovered his form slowly but steadily. The trigger was an old-fashioned 'storm-like' victory against Kim Taek-Yong|Bisu on 20 June 2009 in the Shinhan Bank ProLeague 08-09, after 735 days of silence. He could not qualify for either OSL nor MSL since the Shinhan Bank OSL season 2 in 2006, but at the end of Shinhan Bank ProLeague 09-10 season, Hong ended the season securing a 3-game winning streak, including a dramatic victory against Jaedong. Hong officially announced his retirement from professional gaming on his website on 16 June 2011. At his retirement ceremony, BoxeR jokingly handed him an empty StarCraft 2 box. BoxeR said that the box was empty, but the account was at the SlayerS clan house, and if Hong ever considered transitioning into StarCraft 2, he knew where to go. In August 2011 he appeared on a reality TV series entitled Project A on GOMtv. The series follows Hong as he attempts to qualify for the GOMTV Global StarCraft II League and relaunch his pro gaming career in StarCraft 2. The series premiered on 12 August 2011.

He finished the series as the final champion, beating out other participants including celebrities, Harvard graduate and politician Lee Jun Seok, Mensa member Choi Jung Moon, and legendary pro gambler Jimmy Cha. The prize money was KRW 79,000,000. With this achievement, he received positive comments that he had enhanced the image of pro gamers, not to speak of his own recognition as a genius.

He also collaborated with other veteran Starcraft players to organise tournaments featuring former pro gamers, with the eventual goal of setting up a league for veteran Starcraft players and reviving the fortunes of Starcraft. The first activity was the inaugural "Star Final Four" event match held on 5 February 2014. Hong competed with Kang Min, Park Jun-Suk and Lee Byung-Min. He eventually won the event.
