Eye Space
The concept of eyespace is related to the space available for a group to make eyes. In practice, eyespace is terrain almost or entirely surrounded by the group. In tsumego problems, it is often important to reduce the eyespace by e.g. a hane. See also: Old, short discussion below: Eye space is a property of a group which is transformable into eyes. In practice, eyespace can be terrain almost or entirely surrounded by the group or it can be terrain adjacent to the group which can be made into eyes. Examples of the former are given in most tsumego problems, which often consist of reducing and destroying the opponents eyespace. Examples of the latter are often used to describe connections. E.g. the trumpetconnection is rich on eyespace. There is a thin line betwen the concept of eyespace, eyeshape and 'potential for eyes' - they reflect the fact that it is not just the amount of territory available which decides actual eyes possible, but also the shape of that territory. See also nakade. (I like to think) I use the terms in a distinctly different sense.
You can reduce eyespace, by playing a hane for example. But other people might use the terms differently. This is a copy of the living page "Eye Space" at Sensei's Library. (C) the Authors, published under the OpenContent License V1.0. |
