Miai Values

0,67

[Diagram]

Take corner point being connected back

Initial Count: 8 1/3

A same size move of type "Defend Potential Point, Make Ko" follows (similar above),

so this move is ambiguous.
                 Count 7 2/3                                          Count 9

[Diagram]

defend potential point, make ko

Initial Count 7 2/3
                 Count 8 1/3                                          Count 7

1.33

[Diagram]

Take away nearly 3 potential points

Initial count: 9 2/3

Later, black+triangle - white+cross is ambiguous (0.67)
                 Count 11                                          Count 8 1/3

1.40 (1 2/5)

[Diagram]

Three stage ko

To get a stable position black has to spend 4 moves, White 1 move at (a). This are in total 5 moves.

Black has 3 prisoners and 2 points, White has two points, which gives a 7 points swing value.

So every move in the three step ko is worth 7/5 = 1 2/5 points.


                 Count 5                                          Count 7 with W2 at (a)

1.42 (1 5/12)

[Diagram]
Take stone, take away potential territory  

Count Black first 2

[Diagram]
Protect potential territory, almost save stone  

Count White first - 5/6

Next play is worth 1.17.
Swing value 17/6 / 2 = 17/12 = 1 5/12

[Diagram]

Protect potential territory, almost save stone

Count Left: -2, Count Right 1/3 (cause of 1 prisoner)

Initial Count -5/6
