: ( 716)
White reduces the liberties of Black's group in the top right corner. This starts a classical variation due to Fujisawa Hideyuki [LIT. 1; page 243].
:
This move prevents two eyes for White's group at the lower edge.
: (75 727)
Playing this move at gives an equivalent result.
, :
Reducing White's corner territory to some extent will prove irrelevant here, but these moves might be the technically correct ones.
:
As shown in the corresponding variation of our solution ( 524), it does not help White to capture the hanezeki's tail with a move at , instead, to save her bottom group. Black will win by capturing the entire lower right quadrant.
:
Black can capture the three White stones now.
White's group on the lower edge has only four liberties remaining.
:
Black wins the semeai by one move, and so the game.
