The alert hints that Blue should have doubled.

That doesn't necessarily means that the position as shown is impossible or uninteresting, but still, this is a common and well known situation. If you are Blue here, you really want to have doubled.

Moreover, it hints that there are market losing sequences. Here, after 11/4 and a miss, Blue loses his market by a huge margin if he hasn't already doubled while 8/2 8/7 and miss is still a double/take.

As a consequence, 11/4 will look relatively worse in the hypothetical position (centered cube) than it would in the practical one. This could be misleading if you study only the former.

The score (after 0 games) is: GNUbg 0, You 0

Move number 5: You to play 16

GNUbg	126
You	76
