Yose from Games 5 Solution
    Keywords: EndGame

[Diagram]
Black plays first

B1 removes the main aji in the corner.
Later, W4 - B5 is sente.
The result is +9 (for Black).

[Diagram]
White plays first

B8 fills at WC.
There is no unique solution, but I think that W1 is psychologically best. B2 is not that obvious.
Next, W3 - B8 takes kikashi in the corner.

White plays first (ii)

Now, B1 is tesuji, preventing ko or seki and allowing B3.[1]


[Diagram]
White plays first (iii)

Later, W1 - B2 is sente.

The result is +4.

So this is White's 5-point sente.

In the game, both players overlooked it.

Ko or seki

B5 takes at BC.
If B1 hanes, B3 should normally be at a. W4 is immune to immediate capture, because of snapback.


[Diagram]
Ko or seki (ii)

Now Black can make a seki at a or make a picnic ko for White at b.
