The Mystery of 19×19

Both Lee 9p and Cho 9p are legendary pro players. However, recently Lee Chang Hao 9p scored 3 wins in a row against Cho 9p in world tournaments.

B 15 is a moyo move. It looks more like a move by the famous Takamiya rather than Lee Chang Hao.

Note: I don’t currently intend to provide detailed commentary here because it is difficult to capture so many snapshots. However, I probably can provide a download-able sgf file with some variations. If you would like to see that please leave a comment.

New moves are being invented everyday. For example, white 14 is a very contemporary move. Black chose to not finish the joseki at the bottom left corner, and white did not play the immediate follow-up moves. Rather, white is asking black to make a choice of A, B, or C.

White 100 is the strongest counter move to black 99. However, after

From the first round of the KGS Suk B Choi tournament, http://www.gokgs.com/help/sukbchoi.html.
Between Oysy 9d (B) and Cornel 7d (W).

After Black 17, White has to choose between A,B, and C.

Playing at A is solid but might be a little too conservative because Black will be able to build a nice shape as well. B and C are more aggressive choices.

I recently found a very intriguing game in the 6th World Ing Cup, round 3,
between Kong Jie 7p, China (B) vs. Lee Sedol 9p, Korea (W).

W26 is a brave move. The three white stones on the left side seems really weak now. Most pros would simply play at A.
