This OWL pattern solves the following (new) test case:
loadsgf games/trevor/trevor_32.sgf
320 gg_genmove black
#? [J2]*
(SGF file contents at end of this e-mail.
I have two questions:
GnuGo 3.1.8 claims:
Move at J2 strategically or tactically unsafe
Move at J3 owl-defends G5
How does it determine that J2 is unsafe?
After applying the following pattern, GnuGo now decides:
Move at J2 owl-defends G5
Move at J3 strategically or tactically unsafe
Now, why did J3 become unsafe?
Here's the pattern (added to owl_defendpats.db):
Pattern Dtrevor
OOX| corner tesuji
O.O|
O..|
O.*|
...|
---+
:8,-,value(50)
Now, I don't think we'd want to add it as is, but probably make
it a bit more generic, and I don't know about the value either.
Besides, it has a silly name!
