1. White · K2
This move captures 0 stones. After captures, the connected group containing the new stone has 1 stones and 4 liberties: K1, K3, J2, L2. 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 · J2
This move captures 0 stones. After captures, the connected group containing the new stone has 3 stones and 5 liberties: J1, I2, I3, K3, K4. 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 · I2
This move captures 0 stones. After captures, the connected group containing the new stone has 1 stones and 2 liberties: I1, I3. 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 · I3
This move captures 0 stones. After captures, the connected group containing the new stone has 6 stones and 4 liberties: K3, K4, J1, H1. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
