White: Garcia Bustamante 4d
Black: Eric Lui 7d
Commentary by Michael Redmond 9p and Wang Lih Chen 9p. (Click on the diagram to launch the game viewer. SGF file available here.)
For the first game commentary at the IGF blog we have selected the round two meeting between Garcia Bustamante representing Mexico and Eric Lui playing for the USA. As the Ranka team is busy chasing participants for interviews we had only little time left and unfortunately do not have a complete game commentary ready at this time. We do, however, have two top professionals from the Nihon ki-in, Michael Redmond and Wang Lih Chen talking about the opening and early middle game.
Ranka: How about the joseki in the top left corner, it does look a little old, doesn’t it?
MR: Well, there is nothing wrong with the joseki but, although it might be a personal preference, I wouldn’t pincer as white did in the game at 6.
Ranka: You mean that because of the presence of black stone in the lower left corner it is better to stay away from the left side for the moment?
MR: It’s rather difficult to say what the best thing is to do here. Me, I’d play white 6 at 44 or thereabouts. I’d like to play steady for the time being and just wait and see how things go. Chances are that after the game move at white 6 complicated situations will arise leading to heavy fighting early on in the game.
Ranka: But, the game continues rather quietly even though white played at 6.
MR: Yes, but that how black choose to play, if he’d wanted he could have initiated a more severe approach.
Ranka: After the white kakari at 18 black played his own kakari at 19, wouldn’t it be a natural approach to now player a pincer at the bottom? Playing like that would kill two birds with one stone, playing a pincer at black 19 as well as an extension from white 18.
WLC: I understand what you are trying to say and certainly for white to play somewhere at the bottom with his next move (20) would be a possibility. All the same, the game move of white 20 is a good move. Blacked ignored white 18 so fighting spirit seems to call for playing an aggressive follow up in the lower left bottom.
Ranka: Would playing black 25 at 26 would be too sweet?
MR: If I’d been playing the black stones, before cutting at 27 I’d have liked to play a diagonal move down to the third line (from black 17) to see how white answers. When white answers with some kind of defensive move, which I think is his only option, you still have enough time to cut.
WLC: Black 33 is good.
WLC: Instead of playing at 37 I’d like to play the diagonal move from black 17 (MR’s suggested move instead of black 27) now. Oh, did white play keima at 38 next? Wow, that actually looks very good! I retract my earlier comment and now would like black to play here instead of 37. If you want to do a one-point lesson on this game this would be my choice. It is a vital point for both white’s top territory as well as the black positions at the left and bottom.
Ranka: Do you mean that black instead of 37 should have played at 38 because it helps the bottom black stones?
WLC: Yes, Black is one of those vital points which influence the whole board. Remember, go is not only about the local situation, looking at the whole board is important. Stones that can be used also outside the local context often make for very good moves.
Michael Redmond took some time to come up with a diagram dealing with the situation at the top. It is a hard situation to read out correctly but one thing is sure, the game move of black 51 is likely to result in a do-or-die situation. It’s not easy to say if black overplayed his hand here but, as usual, everything will become clear later in the game. From the many possible variations we choose figure 1 to show you that in the game black got perhaps more than he could have hoped for.
MR: White 40 actually is quite a move. Instinctively one would want to play this move at 46 instead as this diagonal attachment is often the most severest of attacking moves. However, if white plays 40 at 46 black can manage to make a living group or get out without giving up too many points. So, white 40 is a good move. That said, the end result at the top is not really to white’s liking. The culprit here is white 48. (fig. 1) Here you can see what will happen if white plays the nobi at 1. The sequence up to black 6 is pretty straightforward and is the best black can hope for. Although it looks like a trade both players can live with it actually is better for white. As a bonus he has sente to invade the bottom. After white 7 he is having a promising game.
Ranka: Thank you Michael Redmond and Wang Lih Chen!
