Congratulations on your win. :D

A couple of questions on the endgame.

1) Does White have a better play for move 212? If so, how much difference does it make in the final score?

2) What is White's best line of play at move 206? Hint: It's tricky. :)

At 212 I could have played J19.

Still trying to figure out what you have in mind for White 206.

Good. :D How many points difference would that have made?

It's also in the top left. :) Tricky, as I said.

I've been thinking about what you have in mind for White 206. Since Black 207 was at E19, my first thought was that you had E19 in mind, but I don't see how White gets anything out of that. J18 doesn't work, as far as I can tell, and the only other aji I can find on the other side is the peep at B15, but I can't find any way to make that work, either.

Close on both counts. :)

Actually, my thinking is for White to play at H-18 for starters. To create a ko threat. Presumably Black will reply at J-18. Next?

Here is my thinking for White 206.

White starts by throwing in with :w1:, which creates a ko threat at "a" after :b6:. Then :w3: is another throw in to create the ko. :w7: takes the ko, which is a sente ko. In addition, White has the advantage in ko threats, so Black will fill at :b8: sooner or later. (And in this case, sooner is better than later.)

The result of the throw in ko in the top left is that Black has filled at :bc:, leaving a 1/3 pt. ko. By comparison with Black simply playing at D-19, White has gained 2/3 pt., 1 pt. for Black filling minus 1/3 point for the value of the ko. White continues with :w9:, gaining 2/3 pt. Next Black will play :b10: and :b12: to eliminate ko threats, and then will take the final ko in the top left.

A 1/3 point ko. No wonder I couldn't find it. :oops:

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. :mad: 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.

I have taken a quick look at your rating graph. Sure, there are ups and downs, but overall you are about 1/2 stone stronger than you were 6 months ago. That's a quite respectable rate of advancement of about 1 stone per year. :) And you just beat a 3 kyu! :clap: Keep on studying the basics and you could well make a solid 5 kyu rating in another year. Courage, mon vieux, courage! :rambo:

... and fast forward to 2019, it looks like Fedya has indeed achieved a solid 5k on KGS, with some excursions into 4k territory! Was there a decisive breakthrough at some point, or has this just been steady incremental improvement with lots of persistence and hard work? Either way, an inspiring story!
