[gnugo-devel] New owl pattern.

[Trevor Morris]

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!
