cap
A.k.a. boshi. A one skip blocking move, such as white 1 in the diagram, that aims at preventing the opponent from expanding into the centre. The must common reply is at A. When the opponent has not yet settled his stones, a cap is an excellent attacking move. Even if the opponent stones can struggle into the centre, the cap will make that task much more difficult. It isn't even necessary to protect the capping stone - it can usually be profitably sacrificed giving the opponent only a false eye. |
