Hi all, I found another interesting play from Cannes Summer Cup. I present identical positions below.
The first position with the cube in the middle, 13/8 13/9 is by far the best play. However, the second position with the cube owned, 8/4 8/3 is slightly the better play. The swing between two plays is almost 0.1.
Can you explain why? I have some thoughts but I am not sure if I am right.
