Another game. It's already self reviewed lightly, but more tips are definitely welcome.
Main theme of the game is a group I had (skillfully?) killed, but that was resurrected after a liberty problem and a nice netting move later in the game.
I changed my course and I think I was just better than the other player so I was able to come back in the game and actually win quite comfortably.
Still, that blunder shouldn't have happened and it shows again that my killer instinct in Go is below par.
Not resigning. I was close at one point, and sat in front of the board for minutes, going into Byo-Yomi that way.
Big moves when my opponent played slowly in the opening.
Recovering my wits in the endgame and start looking for the biggest moves actively again. (*)
Missed opportunity to wrap up the game easily by letting the dead group come back to live.
Some defensive moves that could really wait a while. Saving a group that is not in danger yet (2 moves away or something)
Loss of concentration in the early endgame and playing a neutral point. (*)

However, if I can't connect and can't run out, I have a one eyed group. So maybe this connection is okay. (because if it doesn't, maybe that group can kill me instead of the other way around.
Hmm I have more liberties, though. But not all of them count. throw ins etc.]

Yes. I had already noticed these white stones getting weaker. But I forgot about them for too long and now they're caught. That means the black group lives.
White has screwed up.
I sat on front of the board for like 3 minutes. I went into Byo-Yomi now and already lost 1x1 minute.
Resigning?
Bill would scold me

SE tells me I'm behind 12 points. During the game I didn't use it, I thought I was behind by at least 20 points.]
