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

202 | # I think this problem summarizes well two common misjudgements | |

204 | # 1. Breaking into an opponents moyo is enormously | |
205 | # undervalued (that is why patterns like LE14--safe jump towards | |
206 | # oppoents moyo--need to have a fixed minimum value, which often leads | |
207 | # bad moves) | |

209 | # highly enough by GNU Go? | |
