Good.

Annoying, but mostly because GNU Go misread. It would still be
interesting to know how the jury reasoned.

Question to the list: In future tournaments with area scoring, should
we run with --play-out-aftermath to avoid similar incidents? For those
who don't know, --play-out-aftermath would make GNU Go play on until
all own living stones except seki are unconditionally alive and all
dead opponent stones are unconditionally dead (or captured).
Unconditionally alive and dead in this context means that they would
remain alive/dead even if the opponent is allowed an arbitrary number
of consecutive moves.

Definitely a catastrophe. We have much tuning to do here.

Surprising considering how many games GNU Go lost, but apparently the
results were overall very inconsistent.

In fact GNU Go lost all 6 games it played against Go Intellect. I
wonder if Go Intellect has received significant tuning against GNU Go.
