So just popping in since it's been a while - january has been a bit slow Go wise, though I'm diligent with my tsumego and monday teaching games (with my teacher) at least.

Thought I'd post a game, one I did win rather easily in the end - but it's of the kind to make me nervous, because I always figure if my opponent can be 1k and play his opening like he did then I'd be in for some fierce fighting and plenty of room to throw it all away. But the game never devolved into complications and I knew myself to be comfortably ahead in the endgame so yeah (I'll admit to getting a bit lucky on the right side, because I played 142 without knowing if there was anything there - I really should be more thorough in my reading since I think spotting the line here should be within my "readability") ...

I'm very interested in how I could have handled his left side invasion better - after I got F10 in I was thinking I should be able to kill him. And, could he have made Ko in the upper right?

Anyway, I'll keep posting games, maybe with some more regularity

The game that made me 1d - though we'll see if it sticks - I kinda doubt it since I feel I got lucky with him dying like he did heh.



I think I played a reasonable game and he messed up a bit in the opening by letting me erase to much of his lower left without him getting too sufficient compensation. Then in the end I screwed up a lot but he did even worse I suppose so.

Anyway, getting to 1d didn't feel special - ribbons didn't drop from the sky nor did I get a personal PM from the secret KGS cabal, I still feel bad about most of my games and think I win by getting lucky and get crushed by being bad. Still kinda proud though, now if only it sticks hehe.

Congratulations! Your quick improvement is an inspiration. Just a few months ago I was giving advice to a 5k in this thread. :)

Two shape/joseki comments:
- n3 is a serious shape mistake: he can cut at o2 and then n2 crawl for a great squeeze.
- likewise s4, now q2 is the tesuji to make you suffer.
Dan players wouldn't let you get away with this!

Thanks both of you!

Yeah, I read up a bit more on that joseki, and played around with the shape some more and saw how much damage he could have done to me if he did the cut. In the game I just shrugged it off a bit as "good enough" until he removed a liberty with N4 - but yeah, that cut / squeeze gives him perfect shape so ouch.

However, after 22 - when I tenuki to Q10 - the result of him cutting isn't good enough compensation no? At least CS didn't mind the result after Q10 - O2 - Q2 so the prior exchange worked out because he misplayed with N4 I guess. I feel like he then compounds his problems by his joseki choice in the upper right.

I blame my ever so slight headache but what is the big problem with S4? is it Q2 R2 S5 S3 Q5 (after which I probably need to go back to take N2, or exchange S6 then take?? Or just Q2 R2 O2 Q1 N2? For the latter, isn't me connecting out much larger than him taking the three stones?

Stuff like these shapes is something my teacher is very good at beating through my thick skull (typically by imploding my position in the endgame through a few innocent looking pokes that are anything but) - but yeah, N3 was a bad auto-play that I should have seen!

I definitively hope dan players let me get away with some stuff heh (otherwise I'm heading below the fold again) - I'm really looking forward to playing dan players even though!

o2 q2 is still a nice exchange for black because it makes m4 sente which is very nice for a big thick wall (and some l2 area yose benefit). The l3 block was really big for the lower left moyo, so if you can't get m4 cut black is happy, I think even if you get sente for q10.

The first, like you say connecting on the side is bigger. So the cut just creates (in sente) the option to take the 3 stones later (so you can count it as half of the points for if black does capture them) which black wouldn;t have if he simply blocked s4 at s5 (his tenuki was kinda crazy!).

Woho! My first win in an even game against a 1d. I've added comments to the SGF - I think my opponent misplayed in the opening and then never complicated the game when he was behind - leaving me with enough points despite bad endgame.

Comments are appreciated!

Congratz on your 1st win against 1d! Also I liked black's position in the early game very much. Your tenuki'ing in some critical moment gained you great momentum imo.

Ugh - so I'm bad at updating this thing - I'm also quite bad at playing Go recently. I still browse the forums / reddit / GoKibitz, but playing has been on a low ever since reaching 1d. Getting games became harder (not a lot, but just enough that I skim the list and then log out because I didn't get anything immediately), and playing on Tygem or FoxGo is a hassle on a mac - I'm tempted to buy a Windows Surface or somesuch just to have access to those servers because I feel that they would be the best places to play to continue improving.

That said, I'm continuing my lessons and I do a fair bit of Go problems so I hope I'm not deteriorating.

A month ago I had the pleasure to play on a real board against my 1~2 dan friend whom I played as my first ever game on a 19x19 board, and just like that game we played even. I lost (kind of big) - after a messy game where I think we both messed up a fair bit, but me much moreso than him. I've gone over the game quite a bit and was at least happy that I found a way to turn it around at one point and we entered the endgame somewhat even (his advantage) - but, the endgame is his favourite part of the game and my worst part, so the small lead became a large one. Anyway, I thought I'd post the game here - input is welcomed (I know I screwed up the upper left joseki, and for my knights move on the bottom I think he should make the empty triangle and cut no?):

Note - I'm black



Ideally I'd remember the endgame properly (the SGF is cut short) but it's a bit vague for me - but he won by 14 points on board + komi

Here are a few things that occurred to me looking through the game. Grains of salt required of course.

Thanks a lot for your comments - they mirror a lot of what we thought when going after the game.

I was completely unfamiliar with the variation in the top left - but yeah, that hane is crucial, and like you pointed out I needed one more move to be honest when I chose the bad variation that I did.

For the bottom left, I'll be honest, I didn't read as far as the Ko until I'd already commited to it - I had a vague hope that it would just be dead, but when I started looking more closely at it I only found the ko, and like you said, I don't really have the threats for it yet.

103 was a chicken move - I need to keep white split here and at least keep us both running. With 107 I was playing desperate to catch up, but yeah, I don't think I have much of a shot here except that white messed up on top (I think he should hane on the inside and just take the points).

A major flaw playing on a real board I found was playing without a clock - so the "accuracy" of our play varied wildly because we'd be spending however much time felt polite just to keep the game progressing decently. Still it's something else to be able to go over the game afterwards on a board and just talk it through. Now I just need to break out of my lull and either get that tablet to play on Tygem etc or be willing to spend the time to find opponents on KGS / rank up on IGS.
