[gnugo-devel] Comments on lazarus.tst

[Gunnar Farneback]

Dan recently added a test suite for the rather infamous
Lazarus-gnugo-3.1.19-200201092246.sgf game. Here are some comments on
this and a patch with proposed changes and additional test cases. The
new test cases could probably need a review.

P8 also looks okay to me, or does it have some problem that I've
missed?

M8 to capture some cutting stones doesn't look out of the question to
me. I would accept that as a correct answer for both test cases.

This should be move 258. P16 isn't the only move to connect. N16 and
O17 also work. Furthermore N16 gives the extra bonus of capturing O16.
