I think move 9 is not a good move pincering in the middle of 2 stones. Although there is the weakness of this invasion my feeling says black plays too early there. But I can't figure out, how to counter it. Maybe I sacrificed the wrong stone? Stretching the other one allows some more efficient attack to the corner. Or should I not go into the corner but instead play M5? Doesn't feel so big. Sorry, but this kind of thing didn't happen in a long time. Can't offer more then "feeling".

Black's 'invasion' is fine. White's long extension is also fine. But you do pull out the wrong stone - by moving out at F5 you would make miai of G6 and J4.

Wait! The upper right invasion by black. Can't you kill that? I think I read somewhere that you have to play ko to survive.

9 is fine but i think 11 is wrong.
i would play 12 at H2.

Thanks for all your answers. Yes, the L&D in the corner was also played wrong by both players. I didn't think enough how to kill it. Played like it would kill itself alone.

Thanks for showing me an alternatives, that actually look like a game.

And no, I didn't do a lot of L&D to get to 3k, like most others. My L&D is a lot worse then for most of my rankmates. I normally win by playing the globally better game (or lose by getting killed very big. Letting 95 or 135 points die in the endgame can happen). With some variations I have no experience and so can't play them well, though. But that is why I ask you guys, right?
The strange moves we see from weaker players are most often made, because they can't make a plan in that situation and they fall back to a combination they might even feel as worse but at least they know how to play it.



If I interprete that correctly, black also pushed its wrong side?
