White first
After
we can expect all of this in sente. Let's count this as -5.5.

Black first, sente
After this sente sequence, the marked point is 0.5 for White and Black makes 3 extra points, for a total of 2.5

Black first, gote
If White leaves it after
in the previous diagram, then Black has at least this sente sequence, or a big ko.
With respect to the original diagram, White loses 5 points and Black gains 2. SO the count here is +7

Black first
Assuming A-B later,
here keeps the score at -2.5
This gives the following tree:
0.5 (6.25)
/ \
7(9.5) -5.5
/ \
7 -2.5
and the value of the move is approximately 6.25
If Black is komaster, then it could be asmuch as a 8 sente.
