[gnugo-devel] how to fix a problem?

[Paul Pogonyshev]

while looking through Trevor's test suites today i discovered trevora:610
problem. a wonderful tesuji! it would be very nice if gnu go knew it.

   A B C D E F G H J

 1 . . . . . . . . . 1     BLACK (X) has captured 1 stones
   A B C D E F G H J

white D2 or F2 invades. this position must be rather common in games.

unfortunately gnu go doesn't even see continuation after white F2, black F3 :(
any ideas of where to place proper patterns? or perhaps there is a way to do
without them? disconnect G3 C3 says D2.
