This move captures 0 stones. After captures, the connected group containing the new stone has 5 stones and 4 liberties: B14, A13, B11, A12. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
3. White · A12
This move captures 0 stones. After captures, the connected group containing the new stone has 2 stones and 3 liberties: A13, A10, B11. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
