Hi.

I just played a crazy 9x9 game just a few minutes ago. I didn't play very well, and I was in time trouble during the last half of the game, but it was very exciting. The position got really complicated, I had no idea what was happening... It was just complete chaos. Hilarious that my small group at the lower right, which was completely doomed right from move 10, ended up living.



Any analysis is appreciated, thanks. I'm sure you'll be able to find lots of mistakes.

Note: At move 53, I was calculating A3, but the time beeping noise stressed me and I forgot if the move I wanted to play was A3 or A4... so I quickly randomly clicked on A4...

B5 - Block, do not let yourself be split. Don't think about the follow up until after.
B7 - Do not play contact moves with strong stones - well, at least they are stronger than yours.
B9 - Ditto. At least try to let the corner life.
B13 - Don't let him connect so easily. Cut the stone off and force it to life independently.
B21 - Think about cutting points.
B43 - This usually only works if W has nowhere to run to behind. Did you read it all out to check?
B53 - Wrong side
B71 - Why? Nothing it threatened

Thank you.
Actually for the opening I meant to sacrifice those two stones, but now I realize that it was surely a bad idea.
For move 71, my idea was that it was threatening G6 which would disconnect White's two groups and threaten to capture White's group at the top right. And I thought that if I just played H1, after White plays G6 I would be forced to play C9 anyway. But now I see that directly playing H1 was much safer because it directly leads to a living group and a clear win by a few points.
For move 43, no I don't think I had read anything for that move because I was in time trouble and I saw that I would lose by just 1.5 or 5.5 points if I did not try to complicate things with this move. But what do you mean by "if W has nowhere to run to behind"?

After W cuts at 44 he could extend instead of atari. If such an extension were to allow him to threaten to connect to stones to the left then that may give him time to capture the B cutting stones. In this case you are okay, but you need to be aware of the possibility.
