#CATEGORY=BAD_PROBLEM
#DESCRIPTION=Not clear enough.
#SEVERITY=0
# From STRATEGY:
#    2.7.178 makes the move at P17 which is better than the game
#    move at P18 but probably inferior to the recommended move at P15.
#    It is not totally clear to me that the move at P15 is really
#    best since the 3-3 point is still open.

#
#    2.7.180: this test passes.
#
#    2.7.220: N12 is found as an owl attack point for the S14 dragon.
#    This attack will probably fail. More seriously, M16 is preferred

#CATEGORY=STRATEGY
#DESCRIPTION=L4 is awkward.
#SEVERITY=2
#    2.7.179: Whether or not the recommended move at G2 is found, the 
#    move at A6 is egregiously bad. In this situation an owl critical 
#    dragon adjoins an owl dead one. We need to revisit our policy for 
#    such situations. The reading code thinks the worm at B4 can be 
#    defended, so this is an owl lunch.
#
#    2.7.180: After revision of semeai.c, the move at A6 is no longer
#    found. Now GNU plays at M16 on the top. Arguably stabilizing
#    the bottom at G2 or (worse but still OK) at J2 is better but
#    I would class this result as ACCEPTABLE.
#
#    3.1.9: Best move here is tough.  GNU Go correctly tries
#    to stabilize G3 group.
