Description (last modified by alain) (diff)

game 36193.sgf Some bad things on one move
At move 20 gnugo 3.7.9 white defend at B3 the stronger group which is alive and does not need defense, and let die the weakest G7.

Correct move 20 is probably F7 or H5.

Dragon status of D4 wrongly changed from alive to unknown after black 19.
With 1000 semeai nodes things are worst: gnugo still defend the strong group but with B1, which protect the cut in B7 but is really ugly.

game twinbot-pedropi.sgf, move 135 B1

gnugo 3.7.9 Top moves:
1. B1  8.69
2. L12 7.62
3. M12 7.36
