In Response To: Boring Race Cube - Can you take it? # 2 (Ian Shaw)

I have the huge GNU one sided DB to the midpoint so I get great accuracy from pos like this with a short # of trials.

The score (after 0 games) is: gnubg 0, user 0 (match to 11 points)

Move number 5: user on roll, cube decision?

Pip counts: gnubg 64, user 62
Position ID: t09DEAC7blMAAA Match ID: UQlgAQAAAAAA

• user doubles

If you move White's checker from the 15 pt to the 13, we are in that database and their is a 4.2 epc difference so, we can safely assume we have about a 6.2 epc diff. in the given pos. I do feel that this race is turn based enough to result in a small pass given a 6.2 epc difference.
