# GNU Go loves this move! (H2 is the point to play here.) It is impossible
# to teach GNU Go not to play there with minor pattern tuning. Problem is
# huge follow_up value; there is no check at all in the move valuation 
# whether a sente move is actually worth something if opponent answers
# (here it is aji-keshi).
# This looses only a few points, but comes up very often.

# GNU Go often plays this inefficient shape. Should be correctable with an

# not mind that, since a cut only strengthens Black.

# I think this problem summarizes well two common misjudgements 
# of the influence function:
# 1. Breaking into an opponents moyo is enormously
# undervalued (that is why patterns like LE14--safe jump towards
# oppoents moyo--need to have a fixed minimum value, which often leads
# bad moves)
# 2. O5 considerably weakens the influence of N5. Maybe this is not weighted
# highly enough by GNU Go?
