The tactics are not a problem; GNU Go understands the importance of
playing L2 and values it to 41 points. The real problem is a known
one, getting confused in semeai analysis. It looks quite stupid too;
after rather bogus reading of T2 vs N9 and L8 vs N9 it considers K6 to
be worth 110 points. Absolutely a relevant testcase.
