Kyuuba
Keywords: Go term
急場
urgent point or area.
See Kyuuba before Ooba, Kyuusho.
- John F. Bill: I wonder whether it's worth making the "point" that point can be too specific - never wrong, but misleading.
- Area/place is the true idea in the opening and it is common, especially with ooba, for their to be two or more possible acceptable points in one area. An obvious example is when an extension is a big play - high or low, or even one point longer or shorter can be valid alternatives.
- Bill: That's a good, er, point, John. ;-) However, in practice, there is hardly ever a local alternative to a kyuuba, while there often is to an ohba.[1]
- But I have been thinking about that because of Kokiri's statement that kyuusho is an alternative. Typically, kyuuba are kyuusho, and for many years I considered them synonyms in the context of go. But now I'm not sure. Kyuusho seems specific. OTOH, there is Takagawa's book, The Vital Points of Go?, which suggests that kyuusho is a fairly broad term. Would you chime in on that? Thanks. :-)
- kokiri I have a vague sense that kyuba is used on a fuseki scale whereas for tsumego kyusho might be preferred.
- John F. I have the same sense. But for those not familiar with ordinary Japanese, I suppose it's useful to make the point that kyuuba and kyuusho are NOT the same. Kyuusho is a specific vital point (e.g. a pressure point in martial arts), but kyuuba means emergency/crisis. Generally, the -ba ending connotes a large area. In a go context, kyuuba should generally be rendered as some variation of "urgent area/point".
- Bill: This page is starting to get cluttered. How about a WME? Maybe moving some discussion to Kyuuba vs Kyuusho? or something?
- (temp) kokiri I concur but I'm not sure a whole new page is warranted - i wouldn't take offence to an edit that removed my input for the sake of clarity. FWIW I thought that whoever wrote
- Japanese for an urgent point, as opposed to Ooba, a big point, or Kyuusho, the vital point of a shape.
- summarised things pretty well.
The following two examples come from the insert, "Ohba, Kyuuba, Dameba", in the April, 1989 issue of Kido.

takes away White's potential base and secures the corner.
[1] Bill: This illustrates John's point (from Jowa, Powerful Fighter (Gohwan Jowa) by Takagi Shoichi, pp. 60 - 61). , the actual move, is the vital point for shape. Takagi likes , however, with this variation if Black responds with . The kyuuba is not confined to a single point.

Takagi comments that White is thick on the top side and is too close.
