Have you noticed that the point numbers are wrong? The home board is on
the left hand side.

The results from the Game 4 (cube action in holding game) are
interesting. Gnubg reports a higher cubeless equity than Snowie, yet
calls it a No Double. Which MET did gnubg use? Myself, I go for
double/take. Gnubg has a big race lead, but with the open 4-point and
14-point instead of 13-point to clear,  I think BGBlitz has a take
despite the slight structural weakness.

Game 7, the blitz, I was very surprised to see No Double come out of
gnubg's rollouts. With 2 on the bar I'd certainly cube and expect to get
a number of passes.

Game 9 BGBlitz to play 51. I think the idea of these multi-slotting
plays is that your opponent isn't likely to leave a shot soon, so you
spread out in order to have the best board in a few rolls time, when
getting a shot is more likely. I'm never quite sure about doing it
myself. I tried it at the weekend, and my opponent promptly ran,
volunteering a shot. 

Game 9 cube action. I would have waited to come down to 2 men on the
midpoint before doubling this. Perhaps I'm too conservative, but two of
White's best numbers, 22 and 44, don't tidy up nearly as well with three
on the midpoint. Not to mention that 66 also fails to clear against a
bar-point game.
For us non-German speakers, what does " Wurfelaktion: Doppeln /
Ablehnen" mean? Did BGBlitz pass?
