1. White · O3
This move captures 0 stones. After captures, the connected group containing the new stone has 1 stones and 2 liberties: O2, P3. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
2. Black · P3
This move captures 0 stones. After captures, the connected group containing the new stone has 4 stones and 2 liberties: P2, Q3. 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 · O2
This move captures 0 stones. After captures, the connected group containing the new stone has 2 stones and 3 liberties: O1, N2, P2. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
4. Black · P2
This move captures 0 stones. After captures, the connected group containing the new stone has 5 stones and 3 liberties: P1, Q2, Q3. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
