Mark Lee wins 3rd Cotsen title

Sunday October 22, 2017

Sweeping all five games, Mark Lee (left, with Eric Cotsen) won his third consecutive Cotsen Open title October 22 at the Korean Culture Center in Los 2017.10.22_cotsen-MarkLee-awardAngeles. All five wins were by resignation, including the exciting Round 4 game Sunday morning against Mateusz Surma. The European professional fell behind early but made skillful use of two weak groups to generate a thrilling game for viewers watching live on KGS as Surma chased a one-eyed dragon across the board. “Mateusz’ attack was a bit stronger than I expected,” said Lee. “I met him four years ago when we studied at the same school and he’s improved a lot since then.” See below for the game record, with commentary and variations by Lee.
Lee donated his $1,000 prize to the American Go Foundation, “to support its work training a new generation of go players.”

Winner’s Report:
Open: Mark Lee (5-0), Aaron Ye (4-1), Andrew Lu (4-1), Xiaocheng Hu (4-1), Mateusz Surma (3-2), Daniel Liu (3-2)

1d-2k: Kim In (4-1), Jay Chan (4-1), Irving Lai (4-1)

Mark Lee goes for “three-peat” at Cotsen Open

Saturday October 21, 2017

To say that defending Cotsen Open champion Mark Lee dominated his opponents in the first three rounds Saturday would not do justice to2017.10.21_MarkLee-right Lee’s play. “This is a slaughter,” said one viewer on KGS as Lee (right) effortlessly erased Daniel Liu’s (left) territory, leaving the 5-dan’s groups struggling pointlessly in Round 2. In the first round, Wang Yi 5d attacked Lee strongly, but was forced to resign after just 134 moves when his eyeless group came up short against Lee’s one-eyed group. In the third round, Aaron Ye, in a tenacious display of fighting spirit, threw everything he had at Lee — despite the relentless pressure of the overtime clock — but was unable to find a way to victory and, like Liu and Yi, was forced to resign.

Lee’s sweep Saturday puts him in position to capture the title for the third year in the final two rounds on Sunday, although Poland’s Mateusz Surma, also 3-0, may have something to say about that. Surma was just in Mexico for the Mexican Go Congress and decided to come up for the Cotsen. The top-board games will be broadcast live on KGS, and see photos on Twitter @theaga.
