=== Examples === See the diagram on the right, and suppose white tries to capture the black groups: :*'''a''': White is not allowed to play '''a''', because a white stone at '''a''' would be captured immediately, and so would be a suicide. :*'''b''': White may play '''b''', because the black group will be completely surrounded ''first'', and thus it is captured, and the black stones will be immediately removed from the board. :*'''c''' & '''d''': White cannot play '''c''' or '''d''' because the black group still has another liberty after one stone is placed. So, playing at '''c''' or '''d''' would be suicide. The black group surrounding '''c''' & '''d''' can never be captured, so it is called ''alive''. The group has two separate liberties, where white cannot play. A group such as '''b''' that cannot become alive is called ''dead''. Groups that are neither ''alive'' nor ''dead'' are called ''unsettled'', and their fate will be resolved later. <div class="thumb tleft"> <div class="thumbinner" style="width:184px; font-size: 88%;"> {{Goban 9x9 |ulE| uE| b| F| F| b| u| u| ur | b| b| b| b| b| b| | | r | l| | | | | | | | r | l| | | | | | | | r | l| | | | | | | | r | l| | | | | | | | r | w| w| w| w| | | | | r | b| b| b| w| | | | | r | dl| b| G| b| w| d| d| d| dr|20}} '''e''' and '''f''' are eyes, '''g''' is a false eye. </div> </div>
