White won, but for playing a 14k it went quite well for me, I think.
(I mostly play 14-16k or SDK, because they have pity on me and accept my challenges. Talking from these experiences, I thought he was very distracted. We both left business unattended and I nearly overlooked I can capture his group!)

He would not do a review, though.

Would you, please?

Congratulations on your game! :)

Just a quick comment. There is a quirk of the corner that you might as well learn right now.

:b77: lose 1 pt. of territory. That seem strange, because White threatens to capture the two Black stones in the corner. Please note that Black gets 2 pts. in the top left corner. But if Black passes she gets 3 pts. there.

If Black passes, White can capture two Black stones.

But after :w78: captures two stones, :b79: makes a snapback, capturing two White stones, for 5 pts. in the corner. Subtract 2 pts. for the two captured Black stones, and White's net score in the corner is 3 pts., as advertised. :)

Thank you, Bill!

I have tsumego where it says "Black to play. Play a snapback / throw-in."

Then, thinking carefully, I'm going "So if I go there he goes there, I go there and atari, and if he beats I will even get a stone more!".
Obviously I need to practice that...

I got time-pressured 3 times near the end, so I tried to play faster when I only had these 30sec intervals, but using 10-15sec per move is still very blitz for me...

This guy really should have told me why he did not play there :lol:
I thought he had overlooked it :roll:

Without using a board:
I think (black) B2 would cut off his left side and, with best play, kill the left group, since he can't make 2 eyes there. Right??

Without a board I can't guess what would happen with his lower right group, but I think that one is stronger and will live.

Yes that's correct! :tmbup:

Other comment on your game: here are two basic bad shapes. Did one, or both of them occur in your game?

Hi Jika,

I'm just a Kyu player myself and really not that strong regarding 9x9, so please take my comments with a truckload of salt, but I hope I could point out a few ideas, that might help you in your next games :)
