The matcher status is less likely to be UNKNOWN than the owl
status is to be UNCHECKED, which is why I recommended using
the matcher status than the owl status. In dragon.c around line 459
we learn that if the owl status is UNCHECKED and the matcher
status is DEAD or CRITICAL then the matcher status is made

If I load this game, GNU Go generates a move at D8, which is the
only move to make 2 eyes. If I load it with --color black then
the move at E8 is generated. (Actually this lets W get a ko
so F6 is a better move.)

The SGF file ends with passes by both players, with W passing first.

Which color is GNU Go?
