[gnugo-devel] semeai question

[Gunnar Farneback]

Currently the semeai code is internally ko aware, but this has not
propagated externally yet. While trying to fix this I've run into the
following code in semeai.c:

      if (best_result == DEAD
          || best_result == UNKNOWN
          || (best_result == ALIVE_IN_SEKI 
              && semeai_results_first[d1][d2] != DEAD)
          || (best_result == semeai_results_first[d1][d2]
              && semeai_certain[d1][d2] > attack_certain)) {
        best_result = semeai_results_first[d1][d2];
        defense_move = semeai_move[d1][d2];
        attack_certain = semeai_certain[d1][d2];
      }

What confuses me is the combination of defense_move and
attack_certain. Why should the last line not be defense_certain?
