Black first  

Let's count this as +7

White first - Black answers  

Let's approximate this as 0.

White first - Black ignores  

This would be -6 with E now becoming much bigger than it was and increased aji around F. It's probably fair to count this as -9.

This gives the following tree

               1.25 (5.75)
              / \
             7  -4.5 (4.5)
                / \
               0  -9

And the value of is about 5.75
