DQFTC: Shouldn't the double get stronger?

Posted By: leobueno
Date: Saturday, 15 March 2014, at 7:34 p.m.

This is my first DQFTC (Donkey Question For Tim Chow).

Note that as the opponent's position worsens, counterintuitively, the double turns to a no-double. What's going on?

The score (after 0 games) is: gnubg 0, Leo 0

Move number 4: Leo on roll, cube decision?
