This group looks dead, but suyang said that we should continue...

For the next game:

1) Territory is not the only principle.

2) Improve the balance for attack and defence vs. territory.

3) If someone makes "endgame moves" = filling dames, watch your liberties! Something is getting killed.

4) If my corner group has a lot of liberties, an invasion inside it may not be problem, IF the neighbouring white groups are weak. Maybe I can surround them.]
