[gnugo-devel] huh, wtf?

[Paul Pogonyshev]

can anyone explain me this piece of code (interface/play_gtp.c, 
around lines 2690, finish_and_score()):

  do {
    move_val = genmove_conservative(&i, &j, next);
    play_move(POS(i, j), next);
    if (move_val >= 0) {
      pass = 0;
      moves++;
    }
    else
      pass++;

    next = OTHER_COLOR(next);
  } while (pass < 2 && moves < board_size * board_size);

what does `moves' serve for?

the reason i stepped on this is a twogtp game where 3.2 and cvs
disagreed on the final score. the game is below.
