1. White · S18
This move captures 0 stones. After captures, the connected group containing the new stone has 1 stones and 2 liberties: S19, R18. 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 · R18
This move captures 0 stones. After captures, the connected group containing the new stone has 3 stones and 5 liberties: R17, Q17, Q19, P18, S19. 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 · S16
This move captures 0 stones. After captures, the connected group containing the new stone has 4 stones and 4 liberties: S14, R14, Q14, P15. 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 · Q17
This move captures 0 stones. After captures, the connected group containing the new stone has 7 stones and 4 liberties: R17, P18, Q19, S19. Diagonal neighbours are not part of the same group. More than one liberty does not by itself establish life; examine the next move.

19 ranks × 19 files · 6 black stones · 8 white stones
Count the liberties of each connected group, not the empty points next to just one stone. Orthogonal contact connects; diagonal contact does not. Try your move, count captures and recount the resulting group’s liberties before comparing the reference.
