I found it surprising that XG wanted to button up with the ace
instead of maximizing builders for the 5pt. I'm guessing that
it's hoping to hit a shot next turn and doesn't want O to have
the chance to hit back from the bar.

I'm also surprised. I would have been thinking in terms of builders for the 5 point, and would have probably played 10/9.
