In Response To: Is this obvious? (happyjuggler0)

As usual when I play I don't strain my brain too hard looking for the best move when my opponent is on roll. So I missed this one and was surprised when her(?) play didn't turn out to be correct. I simply wasn't thinking in terms of getting my board to crash.

I saw 55 as a problem number for white after 6/1 and wasn't sure it was worth it. However, if I (blue) escape with a 6, then 55 is awesome after 6/1. If I don't escape, then most of the time I crash my board at least a little bit, and this takes away the sting from a roll like 64 after clearing the 8pt, or 65 after playing 6/1.

6/1 also helps in the race whenever blue has to play from his home board, especially with a roll like 55 for blue.

By the way, gnu evaluation had the order of best plays correct. The rollout is mere confirmation. I also would've stopped the rollout long before I did if I had better use of my cpu time. This isn't even close.

The score (after 1 game) is: white 1, happyjuggler0 0

Move number 28: white to play 32

Pip counts: white 81, happyjuggler0 92
