[gnugo-devel] two tuning exercises

[Gunnar Farneback]

Appended is a patch which adds and revises some test cases. Two of the
new test cases, from an NNGS game, may serve as good exercises in
tuning.

1. owl:226, an owl reading mistake which should be possible to fix by
adding one or a few owl patterns. Not a trivial exercise but still
limited in scope.

2. strategy4:186, it's urgent to save the dragon in the center, but
instead GNU Go 3.1.9 does something else. Solving this is a question
of identifying and revising a faulty pattern in patterns.db. Trivial
if you're familiar with the engine's workings. If you're not, tracking
this down may be a good way to learn your way around.

To give people some time to try their hands on these I won't fix them
until next week, but I hope someone beats me to it.

I've added the patch to CVS.
