After , it doesn't matter black captures with 'x' or 'y', white can throw in and black has no eye in the corner.
If black plays
at
, white plays 'x'.
White probably wouldn't play and
right the way, but it's sente for white, so it's reasonable to assume white would get them. Ko threat wise, white has
,
, and 'm' before the end game.
Points: 5
Ko threats: 3
Notice black has to capture with 'w' later, so it's one point less than it looks.
Also, if we assume the outside is going to be white's territory, then it's another one point less than it looks. The reason is: black won't get all three of 'x','y', and 'z', because the last one is going to be gote for black and sente for white.
Ko threat wise, there's another ko threat before the end game at 'n' besides . After that, there's another two-point losing threat at 'v'.
Points: 9-2 = 7
Ko threats: 2 + 1 two-point-losing threat
