#CATEGORY=ATARI_ATARI
#DESCRIPTION=GnuGo misses followup to D4 push-through.
#SEVERITY=1
#    This is not as clear cut as it may seem. 2.7.228 values the endgame
#    move at A7 to 6.66 points which seems about correct. The fact that
#    white D4 threatens both to cut off E5-F6 and to capture D3 through
#    a chain of threats (which is what happens in the game) is not that
#    easy to understand.  A more general atari_atari module could
#    perhaps see it, but we are still far from that.  I think this test
#    should be in nicklas3.tst (harder problems).

#CATEGORY=PATTERN_TUNING
#DESCRIPTION=I think G9 is not too terrible here. Very difficult to see.-trevor
#SEVERITY=1
#    This test illustrates a general weakness of GNU Go: It's poor
#    ability to defend its borders.  White can enter blacks domains or
#    capture the E8 group. In the latter case, whites first move is
#    a sacrifice and the capture happens through a chain of threats.
#Added E6, still not thinking G9 is so bad. -trevor

#CATEGORY=SEMEAI_MODULE
#DESCRIPTION=Very tough position.  Even if F1 for B, W E7 is tough.
#SEVERITY=1
#    This is a very good test case for a semeai module. Black F1 threatens
#    to live and creates all the necessary liberties to win the semai.
#I disagree; this it tough; a more clear-cut test case would be helpful
#to better isolate the inherent problem. - trevor

#CATEGORY=SEMEAI
#DESCRIPTION=Tough for white to see attacking B, and linking w/ attack stone.
#SEVERITY=3
#    The only way to live is to attack a neighbour dragon, e.g. the one
#    at F8. But does the owl code really do this by default?
#
#    No, this is up to the semeai module to resolve. /gf

#Note: Owl & Dragon status is both critical for the W group.  Why

#  Dragon status for all of the B stones is Dead.  Can a Critical
#  group kill another group???
