2007 Korean Baduk League, Paek Hongsuk (5d) (Team Ulsan Dearche) - Park Seungcheol (5d) (Team GS KIXX)

This is one more example of manego. The Mirror Go, one player plays each move at a point that "mirrors" his opponent's previous move. Usually, the "mirror" is a 180-degree rotation about the tengen.

The theory behind Mirror Go is that a move that mirrors the opponent's move can't be worse off. Also, the player who mirrors the moves can abort the mirroring process when his opponent makes a bad move, giving him an advantage.

Usually the manego will finished when one player take the tengen. But even after that the mirror can continue.

This is example in game between Paek Hongsuk(5d), black, (Team Ulsan Dearche) and Park Seungcheol(5d), white, (Team GS KIXX) from 2007 Korean Baduk League.

We can see, in that game white successfully used this strategy. One interesting moment in this game, that score in match between these teams was 2:2. That game was impotant, Park Seungcheol, 5 dan, selected mirror statery and won the game.

Paek Hongsuk, (Team Ulsan Dearche)(5p) - Park Seungcheol, (Team GS KIXX)(5p) - W+R

But in that moment white lost is bigger if connect. If atari on selected stone, this variant white end in gote. In any case black must play this variant.

Korean League 2007

Rules: The top players in the Korean rating list will take part in Korean League without passing qualification tournament. Other players have to qualify.

Each team has an official coach. The coaches decide the members of their teams. In addition, they can invite one master who did not qualify (wild card).

Each team consists of 6 players.

The first team (who won the right to decide the members first) invited Lee Sedol. The second team invited Lee Changho. Third one invited Choi Chelhan and so on.

The team selections produced some sensations:
1. Kim Yeonghwan, 8-dan, the coach of "Ulsan Diache" invited Paek Hongseok, 5-dan as the first member of his team.
2. Lee Hongyeol, 9-dan, the coach of "Chael Haje" team invited Pae Chunhe, 1-dan as the second member of his team although many top players were still available, including Yoo Changhyuk, Cho Hunhyun, Rui Naiwei and others. This was surprising!
3. Yun Kihyeon, 9-dan, invited Han Sanghoon, 1-dan as the second member of his team.
4. Chang Suyeong, 9-dan, the coach of "World Meridian" team gave a wild card to Park Chonhan, 1-dan, another unknown player, while it was still possible to invite Seo Bongsu, Choi Myeonghun or other top players, who failed to qualify initially.

In my opinion (Alexander Dinerchtein) the strongest team is "World Meridian", which consists of Choi Chelhan, Yoo Changhyuk, Yun Chunsang, Lee Jaeung, Cho Hyeyeon and Park Chonhan.
