RO with scores reversed

In Response To: Opening 21 With Free Drop (Matt Cohn-Geier)

As MCG points out, the posted position is just DMP. The position with scores reversed is more interesting. Here's a rollout for it. Note how well U (Up 24-21) and V (Variant 24-22, 24-23) play. Equities for U hover around .500 after two moves when the cube will be turned. That's ideal at this score. $ (Slot 13-11, 6-5) tends to have very good and very bad equities when the cube is turned. But, the trailer won't get to play the good positions since the cube will be dropped. So, $ doesn't play well at this score.

The score (after 0 games) is: GNU bg 1, user 2 (match to 3 points, post-Crawford play)

Move number 1: GNU bg to play 21

GNU bg	167
user	167
