Jeez, looking at this now after some sleep, I was even luckier than I thought. Even if I live on the left, black just needs what? 40 points in the center to win, perhaps. Seems quite feasible.

It's a 6-stone handicap game so I guess I need some luck, but perhaps I cut things too close.

I played my game for today. I'm a little afraid to play on my "Brian" account, because somehow I got lucky and that got to 4d - seems a bit high, but maybe if I study a bit more, I can try to play as 4d later.

So I decided to play again on my "Kirby" account, which I'm ranking up.

I played white against 2k:

Some highlights...

I like my enthusiasm, but when something doesn't really work, it doesn't really work. I'm just increasing my loss here, and setting up to lose the game.

I should settle the losses, and be happy.

Position 3
If I *am* going to be stubborn about running to the top, then this seems like a pretty wasted move:

$$ ---------------------------------------[/go]


I can't see a result I really like, but this move isn't doing much.

After that, he gave the game to me, so I don't have much to say.

Those are pretty much my main takeaways.

Biggest thing to try to remember is probably to avoid increasing the loss when I have lost out a little bit.

It's been a little while since I played go online (last time was when I posted here). I had a routine going of waking up at 5am, studying, then playing go. I was losing a lot of sleep, though - usually about 5 or 6 hours of sleep, and I got burnt out last week, and didn't play.

I watched a video online, and the guy brought up a good point that he can be more efficient with more sleep. He claimed that with 9 hours of sleep, he is twice as effective than when he has 6 hours of sleep. I believe he is more efficient with more sleep, and I believe I would be too... But I don't know how much more efficient.

Problem is, if I want to exercise, study go, and play go before work, then I need to get up early. If I want to get 7 or 8 hours of sleep, I have to go to bed early. But it's hard to do that with my family situation. So I'm faced with a decision:
1. Wake up early to do the stuff I want to do before work, but get less sleep (probably around 6 hours)
2. Wake up at a more reasonable time, and then do the stuff I want to do in the evening - I get more sleep, but I'm less active than in the morning, since it's in the evening.
3. Some combination of the above.

So what to do? It's impossible to know the optimal combination without better understanding how effective I am in the morning with little sleep vs. how effective I am in the evening with more sleep. For example, is 6 hour sleep Kirby + morning routine more effective than 8 hour sleep Kirby + evening routine? How about 6.5 hours of sleep? 7.5 hours? To really know, I need to experiment with it: find an objective measure - maybe number of go problems / hour? and measure myself with different amounts of sleep during different times of the day.

That's what I'd like to do in the long run.

But...

I'm going to the Cotsen. That's less than 3 weeks away. So I don't really have time to do this experimentation right now. So I just have to make a decision, go with it, and do my best to prepare for the tournament. After the Cotsen, I can do that experiment stuff and figure out what works best for me.

Since I didn't sustain the 5am thing last week, I decided for now, I'll get up at 7am, do exercise, then go to work. Then evening will be go study and playing a game.

Today was the first day of that routine.

I lost the game. It's the first game I lost in awhile, so does that mean that it's a bad strategy? Or maybe it's just since I didn't play or study much last week. Not sure. I'll try again tomorrow.

Anyway, here is the game:

A couple of my personal feelings.

Position 1

Maybe it's better to just extend here:

I think it might be safer, and I already get into the side. I think it's a decent result. I in the game I was too greedy.

I should just take my losses, and move on. After this, it becomes too difficult...

After this, I think I was behind. So I'll leave it with just these two thoughts for now.

Position 1 your game hane looks better than extend suggestion as that makes c12 inefficient. Problem was you didn't defend the d14 cut when you had the chance (instead of c18 or k16). Maybe it's okay to allow that fight, but d14 connect is simple and good result for you.

In this sort of shape I'd expect black to d14 cut atari then hane connect d18 in sente (do you hanging connect or jump is a question). Then if Black extends e14 you can capture the 2nd line stone in sente which is big for eye space of your now cut group and if Black saves that you capture the cutting stone. Being cut without the b15 capture available was sad.

Thanks for your comments, Uberdude. I was going to inquire about it more, but I think I understand now what you mean about c12 being inefficient. It seems that a big takeaway for me should be that capturing b14 and capturing the cutting stone are miai, so when he protects b14, I need to do something about it.

It feels annoying to do this in gote, but the D10 stone seems inefficient, so maybe it's not all bad for me after this.

Anyway, in some ways it was good for me to lose this game, because it makes me a little more humble. I should think about being more precise during games, though, on Tygem, I usually play faster games than usual.

This should make the inefficiency obvious: White to play, I don't think many people would chose c12 ;-) :

As white I would be happy with this result: it's a nice and thick wall with good eyeshape thanks to the hanging connections so gote is fine. You might think allowing black 3-5 as double sente is sad, but it's not clear it's actually a good exchange as black gains a little territory but white gains good thickness (compare to the modern 3-3 invasion joseki where you don't make this hane connect so that in future the wall can be weak, this wall is super strong now).

If white tries for more and black is obedient then this diagram is probably better than the above for white (in terms of territory at least, in terms of thickness on the upper side white is perhaps somewhat worse). Also it's possible that 4 as hanging connection one line to the right (which is also sente) would be more useful for white in the future (it would in your game) so there's an element of aji keshi here.

But this gives black a chance to correct his mistake and play the sente atari. Now 5 has some aji, for example a peep at a which could be quite useful for black's lower side moyo. This aji doesn't exist with solid d14 connect.

Actually, as black if I wanted to do this kind of thing to annoy white's plans then I'd do the below. After extend of 7 if white captures at 8 it is locally sente on the corner but what if black ignores? (if the following is not to white's liking then 8 could be jump to a instead but then black may continue fighting in the centre or defend at 8 now that white can't cleanly capture the cutting stone).

The shape point of 3 is what made me wonder if white hanging connection of 6 before should have been jump to here instead. I didn't read if 18 is actually sente but let's say it is for illustrative purposes. Black dies in the corner but squeezes from the outside to develop the centre moyo.

Thanks for the diagrams, Uberdude. Very nice variations!

Your arguments are convincing, and I think the connection is good. My biggest concern is that I didn't consider my weakness in that my opponent could cut. Maybe I felt invincible. I may have been getting too confident since I've had a lucky streak.

I'll aim to consider my weaknesses more carefully.

I also think the time setting I get on Tygem is usually too quick, but on the other hand, I ran out of time at the Cotsen before (it's faster than the US Open), so I'm going to need to think more quickly when I play in a couple of weeks.

Happy birthday, by the way.

I played another game on Tygem, and I lost (I'm white). I am not reading that deeply. I think I need to do more go problems.

Here is the game:


I'm happy to have played a game, but I think I can do a bit better reading than I did today.

That being said, in the past, I've gotten into a negative rut. I'm going to try not to do that, and stay positive. The answer here is not to get depressed, but to do some problems, think harder during the game, and play better.

There are a lot of interesting and common variations, but I don't remember them, and I've made mistakes more than once during games because I got confused and played the wrong moves.

---

2nd takeaway: general point - I didn't read that clearly in this game. I played moves without thinking about what the definite result was going to be, and played more based on feeling.

This is not a way to improve.

---

Positive takeaway: I didn't really want to play a game today, but I did anyway. I'm glad that I did, even if it would have been better if I concentrated more.

---

Rating
I'm going to start giving my games ratings. Ratings are scores from 0 to 10, where the rating is based on how I felt I played, independent of whether I won or not.

In this game, I played in a direction I felt comfortable with at the opening, but got confused by an opening pattern pretty quickly. I made a mistake, and then tried to read the result in the lower left. I give myself points for trying to read a little bit, but I didn't read as clearly as I could have. I lost out there. Same in the bottom right - I didn't read clearly what was going to happen, and kind of guessed it. Same with the top right.

I'll give this game a 3.5/10.

Played 4 games at the Ann Arbor go club today. I was white in all, and they were all handicap games. I won them all, and none were really close. I reviewed with the players, but won't transcribe here.

It was fun to be social, though, many members are college students, so I'm the old guy.

While I was playing, the guy who said he was 5d came (who beat me last time). I wanted to play him again with lower handicap today, but I couldn't get the timing to work. When I finished a game, he was playing, and when he finished a game, I was playing.

I'll aim for better timing next time.

Oh, and I met a student that was in the parkour club. He broke his jaw, so he was trying out the go club during his recovery.

Pretty sure if I tried parkour, I'd literally die.

Hi Kirby,

Pretty sure if I tried parkour, I'd literally die.
I don't think so.
You'd start out as 30k, then work on the basics, just like anything else, and make improvements one baby step at a time. :)
But if you try an 8d move now, you might seriously hurt yourself, yes. :blackeye:

I didn't play much last week, again. But I realized it's October, now. So I studied go problems this morning, and played a game. I have only until October 13th for the Cotsen.

I don't know if that's enough time to get strong enough to compete, but I'm going to try. If nothing else, I hope to study and play a game every weekday (club on Thursday). If I can't do that for 10 weekdays, my willpower really has gotten weak.

Anyway, I lost today. Here is the game:

Elf seemed to think the move above was fine, and that I was ahead. But after I lost the ladder, it seemed to think I was way behind.

is a 40% point swing, the difference between me being ahead and behind...

I'll leave it at this, because I'm starting to lose the logic here. Maybe it's a close game for amateurs, but we keep having big swings of win percentage, since we are playing the wrong endgame.

I don't know.

Biggest lesson from Elf

From what I could analyze, Elf had some similar ideas to my own personal review, but one principle that seemed very different was this one:

I was so focused on the black two stones, that I ignored the rest of the board. I think Elf's judgement to be flexible and to take a look at the top side is a good one. The black stones there can kind of escape, but are weak. It's good to move on toward the top.

Note to self: I have to review one space low pincer after I do high 3-4 approach. The variations are pretty common, but I keep spending too much game time thinking when they arise.
