Mark Lee Wins Cotsen Open, Sweeping 5-0

Sunday October 23, 2016

Mark Lee won the 2016 Cotsen Open, scoring a decisive 5-0 sweep in which the only real threat came in Round 3 when he2016.10.23_mark-lee-trophy faced “a very hard situation” against Dae Hyuk “Danny” Ko. In the end he prevailed against Ko by resignation, a similar end for most of the rest of his games, earning a second straight Cotsen title. Lee (center) missed this year’s US Open and says he’s been hard at work studying, but not go. He’s a freshman in college now, where he says his favorite subject is geography. “I like it, but it’s not nearly as much fun as go,” he laughed.

In addition to tournament sponsor Eric Cotsen (right), AGA president Andy Okun (left) thanked Ambassador Lee Key Cheol, Consul General of the Republic of Korea in Los Angeles for his strong support for the Cotsen Open. He also thanked Kim Nakjung, Director of the Korean Cultural Center in Los Angeles, and Seunghoan Roh, General Manager of the KCCLA, which hosted the Cotsen Open this year. “We really appreciate the longstanding support, not just for this great event, but for promoting go throughout the United States,” said Okun. Cotsen, in addition to thanking all the players for showing up, expressed special appreciation to his  tournament team, “who handled this year’s challenges incredibly well.”

Second Time the Charm as Mark Lee 7D Sweeps to Win Cotsen Open

Monday October 26, 2015

Mark Lee fended off a last-round challenge to clinch the 2015 Cotsen Open with a perfect 5-0 record. Lee uncharacteristically misread in a 2015.10.25_cotsen-okun-lee-gross-P1000244capturing race against Ho Son 7D of Seattle but fought back and then pulled ahead decisively in the endgame to win by more than 20 points. Large audiences watched the top-board matches, broadcast by the E-Journal team on both KGS and the AGA’s YouTube channel — where Myungwan Kim 9P and Jennie Shen 2P commented the games live — and Lee’s sharp focus throughout the tournament was impressive. “I was the runner-up last year and really wanted to win this year,” he told the E-Journal. “The games were tough but when I got ahead I tried to stay ahead and when things got complicated I just focused on the immediate problem.” Lee (second from right) donated his $1,000 winnings to the American Go Foundation to support their work with young go players; the donation was gratefully accepted by AGF board member Larry Gross (right), along with AGA President Andy Okun (second from left, next to Eric Cotsen at far left; click here for more photos).

The Cotsen drew a large field of nearly 150, mostly from Southern California but also from other West Coast  and Western states. After several years at the LA Korean Cultural Center, the Cotsen returned this year to the LA Center Studios in downtown Los Angeles. Players feasted on free food truck tacos from Komodo Food on Saturday and Kogi BBQ  on Sunday, and two experienced masseuses massaged out sore muscles (left) as the playe2015.10.25_massage-P1000220rs sweated out their moves over the go boards. 

Tournament sponsor Eric Cotsen said he was “Really happy with the way the tournament went; everyone seemed to have a good time.” Although he didn’t win as many games as he would have liked, a beaming Cotsen said that “I think the game is awesome! The challenge, the people, everything about it. Figuring out a battle and winning the game, it’s just an awesome feeling.”
