A 1/3 point ko. No wonder I couldn't find it.
More seriously, when I posted the previous game I said there was good news and bad news. The bad news is that I got up to 5k KGS for all of one game. I promptly started losing game after game, to the point that I've been demoted to 7k again. I feel like I have to start all over from the beginning again.
It's tough not to get frustrated when I don't see what I'm doing differently in all the games I'm losing as opposed to all the games that I was winning to get to 5k.
And sometimes for all the work I've done I wonder how much I've really learned. I feel like I'm having the same problems in my game that I did when I started this thread months ago: my opponents get lots of territory from their moyos and I don't; pincer attacks work for them but not for me; and don't get me started on thickness. If I make frivolous comments about 1/3 point kos, it's because almost all of my games are decided well before the endgame, so there are more important things to focus on if I want to improve.

Keep on studying the basics and you could well make a solid 5 kyu rating in another year. Courage, mon vieux, courage!
