Dear Álvaro,
It looks like "remove all dead stones" doesn't always
I checked this. White never pass if position is losing in Tromp/Taylor
rule. In this case, white can win even if not removing last black
stone. And with something unlucky, pass was selected.
And when a player is winning with big margin like +30.5, both player
tend to play bad move, like self-atari, filling eye, breaking seki,
if those moves do not change the result.
So it is maybe not good at ownership map.
Thanks,
Hiroshi Yamashita

Dear Yamashita,
This is a great resource and I am very thankful that you made it available
to all of us.
One minor issue: It looks like "remove all dead stones" doesn't always
work. An example is 206_19_0114_2k_r16_add300_7/20170312_0018_05484.sgf ,
where a black stone at P18 is left on the board for no apparent reason. Do
you know why white passed on move 420?
I haven't studied how often this happens, but it means I will need to do
some additional processing before I can use the final ownership map as
something that a DCNN would predict.
Thanks!
Álvaro.
