I've found what I believe is a bug in GNU Go's twogtp.py script,
which allows two GTP programs to play against each other. Please
correct me if I'm wrong. If someone here is involved in the GNU Go
project, and I'm right, please fix the bug for the next release.
The problem is in the play() method of the GTP_game class. When it's
black's turn, we see this:
self.moves.append(move)
if string.lower(move[:4]) == "pass":
passes = passes + 1
if verbose >= 1:
print "White passes"
else:
passes = 0
self.whiteplayer.black(move)
if verbose >= 1:
print "Black plays " + move
Shouldn't that be "Black passes" instead of "White passes"? There's a
similar inversion for white's turn. This causes some very strange
reporting, where it looks like one player gets several moves in a row.
