Dia 1-1: Black plays 1 Dia 1-2: and takes one stone Dia 1-3: Capturing one stone...

During a Go game one or more stones can be captured by completely surrounding them, i.e. filling all empty points around them. We show two examples: on the left a one stone capture, on the right a three stone capture. Once black has played 1 he removes the captured white stones from the board leading to the 2nd diagram positions.

Dia 2-1: Black plays 1 Dia 2-2: and takes three stones! Dia 2-3: Capturing three stones...

Note 1: Needless to say that being captured usually is bad. There are numerous situations though where one would sacrifice one or more stones just to gain an advantage elsewhere.
