1. Black · J1
This move captures 0 stones. After captures, the connected group containing the new stone has 1 stones and 2 liberties: I1, K1. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
2. White · I1
This move captures 0 stones. After captures, the connected group containing the new stone has 1 stones and 2 liberties: I2, H1. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
3. Black · H2
This move captures 0 stones. After captures, the connected group containing the new stone has 5 stones and 8 liberties: H1, G2, I2, G3, G4, H6, G5, I6. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.
