Hi,

why is the top right area lost for black? With black j13, can't black win the territory later - and make prisoners? I'm completely confused about this. Also, if there was black j13, why is this whites territory? Probably a simple rules question.
If I may ask you to have a look? See attached, or this: http://www.dragongoserver.net/game.php?gid=728335
Unfortunately I cannot embed, because it's 13x13.

Thx.

J13 K13, black is dead.

Even if J13 worked, you would still need to play it if you want the points.

If you thought that then you should have played it out. But, I do not believe black could have won that corner without a lot of help from white.

If black plays j13 his group has three liberties and whites corner group has four. Even if white gave black two moves in a row white should still win that corner.

See move 72. Black cannot win the fight and the Black stones are dead.

¿Es claro? :)

Ugh! What an easy task, thanks guys! I didn't see the 5 black stones can be cought. I was somewhat overfocused on those 5 dead stones plus l9 m9 n9 n10, which surround the white stones.
