Value of ?  

Step 1

          ?
         / \
        6   ?
           / \
          ?   0
         / \
        7   ?
           / \
        5.33  3

Step 2

         4.4 (1.6)
         / \
        6  2.79 (2.79)
           / \
 (1.42) 5.58  0
         / \
        7  4.17 (1.17)
           / \
        5.33  3

Step 3a - 1.6 < 2.79, so is sente

        5.58 (0.42)
         / \
        6  5.58
           /
 (1.42) 5.58
         / \
        7  4.17 (1.17)
           / \
        5.33  3

Step 3b - 0.42 < 1.42, so (response to ) is sente

        5.08 (0.92)
         / \
        6  4.17
           /
        4.17
           \
           4.17 (1.17)
           / \
        5.33  3

Step 3c - 0.92 < 1.17, so (response to ) is sente

        5.33 (0.67)
         / \
        6  5.33
           /
        5.33
           \
           5.33
           /
        5.33

No inconsistencies left, so a move in this position is worth 0.67 points (sente for White) (exact: 2/3).
