2. Black · P6
This move captures 0 stones. After captures, the connected group containing the new stone has 5 stones and 5 liberties: P5, O6, R6, Q4, R5. 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 · P5
