Trevor's views are indispensible for seeing what is going on
with the regressions.
I browsed Tristan's tests (except global.tst) and had some
comments. I didn't comment on ones Gunnar had already commented
on (via his patch) unless I had something to add.
capture test 4: The comment in Gunnar's patch (already in the CVS)
shows that the recommended H5 may not work. But
B:H6 might be the correct answer.
capture test 5: It looks to me as if S3 doesn't work. After
W:S3 B:S2 W:T2 B:S1 W:O1 B:S5 black wins the semeai.
vie test 8 : Instinctively I want to play R7 which is GNU
Go's move. However this leaves W the move at Q8
so maybe R8 is best. I find it hard to believe
the recommended S9 is good. B has a half eye
at N7.
vie test 17 : GNU Go plays at E6 which probably lives though
maybe E2 is better.
vie test 20 : The recommended answer H9 and GNU Go's Q14 are
both unnecessary. B is alive as it stands. (J8
and H9 are miai.)
vie test 27 : After GNU Go's answer at F3 it looks as if B is OK.
vie test 38 : GNU Go's answer at A4 works and is a little better.
Interesting position.
vie test 39 : GNU Go's answer at D7 lives but is one point smaller
yose. A replacement pattern would fix that (though
not within the owl code.)
vie test 50 : Looks to me like this becomes ko after
B:G14 W:H15 B:G15 W:K17 B:J17 W:L16 B:J19 W:K19.
