Nice to hear that your attitude towards Go is becoming more relaxed!


I'm happy about it!
Maybe we can still finish our Jubango later on? I'd really like that. Though perhaps with a 2 stone handicap or something? Let me know if you're open to it. Doesn't have to be now or even necessarily soon, but in the (near-ish) future. :)

Yes, I would be pleased to resume our jubango. We could start with 2 stones handicap and change after 2-3 games if games are too hard for one of us. I am free most thursday evenings 18:00 or 18:30, or saturday mornings or sunday mornings (but I'll be away on November 2 et 3). When you feel ready, please PM me and we can arrange our next match.

This was another fun game, where I think I did a lot of things right.
I was white in this particular game.
My thoughts, alongside Leela's tips, are:

- 32 is a pussy move. Afraid to fight when you kick, so fall back instead. Should've kicked it, probably.
- Direct result: 34 felt uncomfortable. Also shows that 30 was not a very good move, either.
- 36: mistake. Direct result of thinking of recognising a shape and then not reading properly to find out. BIG NO NO

- 88 was a dangerous move. I was very aware of my cutting point at D8. I think in this game I played rather well concerning defending my weaknesses, not leaving too many behind. But here I went for a looser defense. That is more risky. And here even Leela says: just defend it directly.
- 90 is a direct result, I defend it again.

- with 96, I start my direct attack on the middle.
- From 97 to 127 I feel like I win the game. My opponent doesn't seem to see what's going on in the middle (playing very fast), meanwhile I am giving up some stones locally to surround the middle entirely and also making sure I'm alive at the bottom.

-150 was a mistaaaake!
But he didn't notice :)
- 154, no need to do this now. Essentially a pass.

And then my biggest mistakes in this game. Starting with black cutting at 163. And here I want to ask someone stronger: how/where did I go wrong? Was there a way to keep those stones captured, or did I had to let them leave? Maybe his stones were out and I had to save my stones. Instead I try to keep them in and I lose my stones in the process.

Luckily I had enough points to still win the game!
It was fun!

I could analyze all the mistakes move by move but there is really just one general principle you needed to follow here and that is to count liberties. Whoever's liberties are reduced to zero first loses the capturing race.

Here are the number of liberties of their group and your group after every move:

165: 4 / 5
166: 4 / 5
167: 5 / 4
168: 4 / 5
169: 4 / 5
170: 4 / 5
171: 4 / 4
172: 4 / 5
173: 4 / 4
174: 4 / 3
175: 4 / 3
176: 3 / 3
177: 3 / 2
178: 2 / 2
179: 2 / 1
180: 1 / 1
181: 1 / 0

Look over the sequence again with these numbers as a reference.

The :bc: stones have 4 dame now, as do :b63: and :b65:, but they threaten to jump to a. The :wc: stones have 5 dame now. However if the :bc: stone try to escape and are prevented, both the :bc: stones and the :wc: stones will have only 3 dame left. Is there a play that will reduce the dame count of :b63: and :b65:, and also meet the threat of the jump to a?

Playing Jubango game 6 with jlt reminds me why it's good to be back playing Go :)
It was a close game, and I really enjoyed it, there were some very interesting board positions.

In the end, I regretted it :p but I didn't want to double approach (don't really like those joseki, to be honest) so I decided to go for this. It played out interestingly, too.

This was also interesting:

This I originally wanted to do. But I figured it hurt my corner a lot, so I decided to go for a light reduction. (well, at least that's what I thought it'd be.

Whole game can be checked here


What I should learn from this:
Biggest mistake: too many (slow, small) gote moves, giving away the initiative. Many moves I wanted to play, were played by my opponent instead.
2 main causes:
- Bad time management. Had 1h + 5x30s, in the end I still had over 20 minutes. Not enough thinking (only using a lot of time on strategic choices, not enough on reading)
- low confidence in my own reading. Thus, extra defensive moves, way too slow.

What I noted when observing mid-dan or stronger players is that
  • they spend a lot of time thinking at every stage of the game, including the early opening, even when I have the wrong impression that there is nothing to think about.
  • they sometimes win fights without any fancy moves. The sequence flows naturally, and a group gets captured at move 10.
  • When commenting other people's games, they easily come up with sequences that are 10+ moves long.

So I concluded that to improve my play, spending time to read is necessary (although obviously not sufficient). Hopefully, reading skill will improve with practice, but certainly not without practice.
