Life In 19x19

Either by yourself or with an opponent, would you be able to play a fresh game entirely in your head? Would anyone be able to do this in real life like Touya Akira?

Me? Good lord, no. For one thing, that would require each of us calling out our moves by coordinates. Disaster Number One right ...

Self-promoting, but accurate at the time, and I haven't heard of any updates that change the situation.

Note the link to GoGoD: John wrote about how Bao Yun had significantly exceeded other players' marks, and played a complete game, whereas all the previous professional attempts had ended ...

I'm worried about the double atari white has, but by the meta-argument of "a pro wouldn't have missed that", it's probably not as worrying for black as I thought at first. It would probably be a trade of white ruining black's territory while black ruin white's wall.

Then, white has pushed from ...

This awful move loses even less:

Interesting. I have a question/comment though...

His book dates from March 2017 and so is really about AI based on training with human games rather than self-play. That doesn't matter too much here, though it does explain why Yi played the odd "shimari" in the lower right. He wanted to achieve a ...

Perhaps you recognize a pattern? Often, humans tend to have an opposite problem . In no particular order...
all dates seem to be after alphago ;
B won 5 out of 8 (sampling size too small? ) ;
countries (unlikely any correlation) ;
unknown ages (unlikely any correlation) ;
genders (unlikely ...

Well all winstreak must end one day.



I feel I add the better position starting the middle game, and I might have been able to kill the lower side black group, but then I overplayed like crazy in the middle.

My first instinct is black : he has solid territory, some potential to develop and a weak group to attack. That said, white has a nice position on the left and the top isn't bad either if a bit open. And white has sente.

With sente white can play an extension on the right and black lose his attack ...

Mirror go cannot be a good strategy. There is no need for a bot to invent anti-mirror strategies. When Black plays, he tries to find the best move, but there is no reason why White's best move should be the mirror image of Black's last move.

Here is a game of myself against LeelaZero. I stopped ...

Over the last ten days or so I've had a rather good 7 games winning streak on IGS, ranking up to 3k+. This is the last of those games : I feel I had the better position, and then he just died everywhere. It made for a fast game.

As for time, well... It's really because the 10/25 is unnecessarily slow for this level of play but it's impossible to get a game quickly on IGS at faster time limit. I don't try to move especially quickly and I play when I felt I have read the situation to an acceptable extant. (It definitely ...

Is this really a positional judgement problem? Who is ahead here seems to depend only on the outcome of the left side fight.

Without deep reading, I feel that white can't save both of his group. So it depends on whether he can make enough use of the four stones as a sacrifice to kill (or get ...

That's probably the largest single group I've killed in a while. It was quite unexpected too.

Black 111 was probably the losing move. I don't think I even need to kill after that. Though White 132 was probably too stubborn of me, I think I might ...

Your time usage could be an issue. For most part you are playing 25 moves in under 3 minutes in this 10/25 game, that is judging from the clock in the sgf. I think you are playing way too fast. Especially in situation that are difficult.

Some comments:


White could have connected with 120 at ...

Setting aside how to deal with :w98: - I would suggest a much simpler thing to think about first is :b97:.

Do you really need to play this move? Unless you're playing blitz or don't actually have enough clock to think through, this is exactly the kind of moment where it's really worth spending the ...
