Life In 19x19

Greetings go friends.
Here i submit a game where I afterwards think that the result isn't quite correct. We passed and counted the game: w+2,5. I want your help to determine the optimal best endgame (from both black and white) from the end position.

So see this as a endgame problem. If you want feel free to analyse the whole game of course.

Thanks in advance

The top is interesting, but I think with perfect play white is fine.

I think there's something in the top right for White with S16 - R16 - S18.

I'm really not sure about the top right corner but it seems like black can win in any case.

Thanks a lot for those variations. I wonder: 265 @ H13 is not it a little bit better?

Ah yeah that does look better. Then I guess white will have to give up the 2 stones at H12.
