One of my best games lately. Very tough opponent. And I played totally different style than usual, so I need a few words of wisdom from you, dear L19 go players.

Half point loss. I could say "it was just a yose mistake" but it would be a baby crying. There were much more and bigger mistakes earlier in the game.

I was white and played a good fuseki in my opinion, then chuban goes badly and all I could do was hunt for a prey. But i'm only 3k EGF, so even if I'm 2d online I'm still full of kyu'ish way of playing.

There was huge life and death on the right side but I was not able to find a killing sequence so I left it as it stands and took a center. but as I said - my opponent was tough and he fought well enough to win a game.

My dear fellow go players - please review and criticise everything you find in this game: things I played badly, things I could play better etc.

P.s. Yose winning move can be included too

Since the OP is stronger than I am, it would not be my place to provide commentary. Still, for the convenience of everyone...

Well, I am sleepy, and weaker than you, but what is 214 doing?

edit: quite sleepy: totally overlooked the eye above--thought white would have to connect. Thanks, skydyr.

214 is 1 pt. in gote, creating a point to the right of it.

I was surprised by how effective b43 is. There doesn't seem to be any good reply from W, which makes me think that w38 was premature - if you look at the board after b37, black has a very loose claim over the left and upper-left, but the invasion solidifies that claim without giving W any counter-attack on top - if anything, those three stones become a burden (and indeed, two of them are eventually captured).

One idea for W38 would be to invade on the left side (the most open part of the board). Perhaps this will be called dull.

Thanks - indeed, invasion there could give white a different/little easier game, black would not get so much territory so much early for free...

@Tekesta - every feedback is good. I'm totally blind looking at my own games and every new perspective is very useful. Thanks for putting this game as eidogo board

Disclaimer: I'm weaker than you so probably my advise is rubbish.

I found a pretty big mistake in my opinion, maybe I'm overseeing something though.
The difference is at least 10 points. (I checked)

At move 188 there is a semai.

In the semai white group has 5 liberties and one shared.
Black group has 4 liberties and one shared.

So this means you (white) are one ahead but still white removes one more liberty at J6.
Instead white should play at P14 I think, 10 points difference.

Hope this helps and let me know if I overlooked something.

Cheers,
Otenki

Yes, you are right, this is this "half point yose mistake" that decided a game, ok, maybe 10 points . The funny thing is it was all correspondence game so I should read everything carefully having more than 6 days for a move.

Some thoughts.

It seems like you don't like making moyos. You had a lot of good chances to enclose large areas.

Also you created a lot of weak groups in the middle game.


edit: Oops I misread

How about M10
Since Black can't atari down.

Thanks for your comments! I will answer in sgf file below. I will try to address most of your proposition. They are moves that I considered for a while and decided not to play them, and this rationalization behind my plays would be quite interesting for some.

Some responses.

I don't think you actually needed to kill the whole big black group at

But I totally missed that you did have to kill the big black group at around

This game feels very "all-in" which makes me nervous

But at the same time very fun game to discuss :]

I have to say I agree with Unusedname about . The thickness that you create with M7 doesn't seem good because you're already strong in that area, it's too far from black's stones and so doesn't give you anything to attack and it's really awkward to try and turn it in to territory. I think it was this poor choice of direction that lead to you having to play the greedy move at and then being left with no choice but to kill black's invasion.

That being said, you are a lot stronger than me so maybe you're right.

P.s. I also think the thickness you made with 38-45 was also a little awkward so maybe that's where the real problems started.

@Unusedname - your proposition for is interesting. Nice catch.

@Splatted - at first I thought I can kill, but this was too much for me, maybe someone stronger could attack in more efficient way and kills this group. As for a direction of attack - I can't tell if my option was better than yours, it was just feeling how to play, and of course I don't like use walls for territory.

Fair enough. I thought from your earlier comment that you were just aiming to build thickness.
