Choi "Acorn" Cheon-ju is a South Korean player who is currently the top laner for Saint Gaming.
Choi "ChuChu" Cheon-ju was a part of the original roster of RoMg as their top laner in early 2012. The team qualified for Azubu The Champions Summer 2012 where they took a game off of Azubu Frost, the eventual champions; however, even with their win, they still failed to advance from groups.
Cheonju changed his name again at the beginning of the new season, this time to "Acorn". Success finally came for Blue in the 2014 Season, when they finally made it out of groups at PANDORA.TV Champions Winter 2013-2014. Unfortunately, they ran into the undefeated SK Telecom T1 K and were knocked out of the tournament 3-0 by them. However, Blue truly made their mark when they defeated NaJin White Shield 3-1 in the finals of HOT6iX Champions Spring 2014 to bring Samsung its first OGN victory. Blue's hot streak continued at HOT6iX Champions Summer 2014 but this time falling in the finals 3-2 to the KT Rolster Arrows. The team's strong season granted them the top Korean seed to the 2014 Season World Championship. Blue was one of the favorites coming into Worlds but their sister team, Samsung White, knocked them out 3-0 in the semifinals of the tournament. On November 17th, 2014, it was officially announced, that all remaining members of Samsung White and Samsung Blue left their teams.
