Cho recently lost the Honindo to Takao with only 2 wins in the 6 games played. Cho’s record again Takao (see table below sourced from http://gobase.org/information/games/) could be better – out of 9 games played there are 6 wins for Takao compared to 3 for Cho. The 31st Mejin was shaping up much the same, with Takao winning the first two games. Cho U proved he was not a pushover with a decisive win in the 3rd game. The first three games of the 31st Mejin are here for your study and enjoyment. Please note: Meijin game 4 will be covered live on IGS-PandaNet.

The outcome of this fight Problem 1 – Black to play determined the game. This position came from an IGS game played between Moto162 (5 dan) and Lucky7 (7 dan). White 187 was a gote yose on the other side of the board, how should Black play here? Problem 4 – Black to play This is not from a real game, but it should be easy if you remember the tesuji lesson from last month. Problem 2 - White to play A problem for White (from a game between David Mitchell and Robert Vardas at the Sydney Go Club). JAL CUP - The 27th WAGC Round 7 Played on 31st May 2006 Black BENCHARIT (THA) vs. White CANGAS (ESP) Figure 1 (moves 1 to 5) Black 5 is a strange move and inconsistent with the san-san of 3. When playing hoshi or san-san in a corner you are playing a single move to finish that corner, there are follow ups but the intent is to play elsewhere. In professional games the most common continuations to these first 4 moves are ‘a’, ‘b’ and ‘c’ in Diagram 1. There are several reasons for this, first, the corner is more important than side or centre; second, Black has no urgent play in his two corners and finally White’s corner is open and vulnerable to a Black attack, Black should take the optioned before White can defend. Diagram 1 Just one more thing about Black 5. If Black were planning two moves in the lower right he would normally look for a shimari such as Diagram 2, 3 or 4. Diagrams 2 and 3 are similar to the game, they secure the corner and can be extended along the side. In the game (Black 5) is high and can be approached along the lower side, the shimaris in Diagrams 2 or 3 have no such weakness. It is possible Black has a liking for this shape, or perhaps he feels this will unsettle his opponent. Nevertheless, the professional move is in the upper left. Diagram 2 Diagram 3 Diagram 4 Figure 2 (moves 6 to 12) White 6 makes the Shimari and Black 7 is to be expected. White 8 lacks decisiveness, playing in the middle of the side like this surrenders the intiative to your opponent – you are saying, “I don't mind which way you go, I’ll let you choose.” – You should avoid giving the initiative to your opponent, make your own decisions and plans, then stick to them. Black’s natural reaction is to invade, not build, this is easy to understand because Black has made a large framework and is stretched rather thinly. The best place to invade is a place where you can also attack. The weakest stone in Black’s framework is the upper right Hoshi stone (1 in Figure 1). Therefore the best approach is to attack at 10, but what are the consequences.
