I'm satisfied with this result because my previous lower right corner exchange is definitely my gain.

I can't think of a way for white to prevent me from capturing those stones.


I definitely lost a lot back there. I think it started with this sequence:

I was naive, and I assumed white would hane, giving me additional forcing moves in the area:

Admittedly, it's not that much better, but I think it's better than the game.

Maybe I shouldn't have played tenuki earlier:

I'm not 100% sure about the precise root of the problem, but for sure, there was a problem, and it gave him an edge in that last fight.


So assuming I have sente, this brings us to a new crossroads in the game. Where are we now? Should I resign?

Objectively, how many points does white have?

Something like 68 + komi? So maybe 75 + potential.

Generously, maybe 62 points? That's about a 10-15 point deficit.

That's not including white's potential.

Looks somewhat grim.

I need to gain about 15 points without him gaining anything. Is that possible? There's still a ways to go in this game, but most of the board has been filled.

The area of greatest potential for both sides seems to be in the marked area.

But white has no real weak groups.


Very difficult. Should I resign? It's possible to come back from a 20 point deficit in the endgame, but that's when one player's endgame is significantly better than his opponent's.

Can I play that much better endgame than him?


And before talking about endgame, I'm the one that's thin. He's thick and strong everywhere.

Looks grim.

But white has no real weak groups.


My sense of this is that both black and white have strong groups in the area. White on the left and upper right, and black on the right and a bit on the top. As such, the area is most likely to result in an even split or to turn into dame, making it effectively worthless.

There does seem to be value to extending into it to thicken black's group on the right and remove aji from R14. Apart from the game move, I'm looking most at C18, which stabilizes black's top group and may end up being sente.

I am behind this game. But there is still a chance.

I will always remember the last game I played of the 2015 US Go Congress. I had a good record up until then, winning 5 out of the 5 games I had played so far.

Since I had been winning as 1d, I was paired against a 3d for the last game, and I was white.

The board position was something like the following:

I misplayed a joseki in the top left, and a few moves from now, all of the marked white stones were captured. The game was clearly good for black.

Somehow, I won the game by 2.5 points. I didn't capture a big group, and didn't revive what he had captured. The only thing I can attribute to winning is that I didn't give up.

I don't know if the same kind of turnaround is possible this game.

But at least for a little while longer, I won't give up.

Black's last hane was big, and it removes a lot of aji from my R14 stone. If I respond with hane, I'm giving black sente profit, so I chose to play here, which stabilizes my group while weakens black's. I think black will respond with C18 which is usually about gote 15 points. The problem is where I should play next. I do seem to be leading a bit but can't say it's more than 10 points. Both black and white has stable shapes everywhere, so from here will be boring but very difficult series of endgame calculation.

I don't understand this move. Usually it works when the threat of atari and playing on top is bad for your opponent, but here I'm not sure I care.

I think that White should have finished up the bottom as shown below before connecting at 10.

As a result, I think that Black should immediately hane at the bottom. White is unable to block at O2 now.
