It's Monday, so another game at lunch. I worked from home on Friday, so my schedule was screwed up and didn't play a game then. Today, it got really snowy in Ann Arbor. Brrr...

Anyway, I played on KGS automatch, and got paired with otenki from the forum here. He was ranked as 4k?, but I think it's a new account (he's been winning). His profile here says he's EGF 2k, so I was in over my head and had to give 5 stones.

here's the game:


As you can see, I won on a fluke - if he just protects from that hane, I can live on bottom, I think, but not very big - and he has sente. He's definitely winning.

Edit: Original SGF is screwed up, so I took out the comments, and you can see it here:

Bottom line is, I think if he just answers my threat here:

He seems totally fine. I don't know what to do next. I imagine this sequence:

Then black has sente, and I have very few points. Marked stones are particularly weak, too. Seems like a hard game for me.

Will go back to work for now - handicap games are hard.

I analyzed this game a little bit more when I got home, a little with some version of LZ, and more with KataGo.

A couple of points...

1. I'm still behind when black resigned. However, there is some psychological aspect, because I did gain a bit of ground capturing his stones in the center. According to KataGo, though, I go from something like a 60 point deficit at the beginning of the game to around a 20 point deficit after capturing that center group. So I'm gaining ground with that capture, but the game is far from over.

2. Next, I did some analysis with a komi of something like 62 - made the game around even at the start of the 5 stone game. Then, I analyzed the game from there. Here are some turning points...

These two moves, above, by black gave a slight dip. KataGo wants to be more active like this:

Anyway, slight dip, but somewhat minor.

Next significant swing is due to my mistake. KataGo doesn't like my atari strategy here:

I suppose I'm being impatient. My idea is to make the marked black stone a target, and hopefully the pressure induces more mistakes. KataGo is thinking something along the lines of 'a' or 'b', below:

That being said, a brief look with LZ seems to show that it's OK with the atari... But maybe the evaluation is different when black is so far ahead. I think I trust LZ more for even games, but KataGo seems like a better model for handicap games, since the points are more relevant.

KataGo didn't really like black's move here:

Preferring instead to drive down the middle to split white at the marked intersection.

On my side, KataGo found this to be a huge mistake:

Since it's not really working - I didn't read a way for it to work, after all... I should not play it. Instead, I should cut my losses and just take some bottom territory:

Somehow, I'm attached to the stones, and want everything - even in a 5-stone handicap game... :-S

In the same fashion, this was another overplay by me:

And he'll just defend. So I should start a fight with the two stones, and maybe I can get that white stone for free.

I'm OK with that type of reasoning. But what's wrong is that I ignored my own weaknesses. After I cut off the stones, black can bite back:

I think this is the gist of the review...

Takeaways for me? I think that it can be highlighted in the following:
* I look for my opponents' weaknesses, yet I'm blind to my own.

There's the saying, the best defense is a good offense. I think it's a good idea, but perhaps it's time for a new mantra.

I was snowed in today - a lot of snow hit where I'm living over the past couple of days, so I decided to work from home. I had plans to play a game at lunchtime, but somehow, there was some sort of urgent bug that needed to be fixed for my work. So I focused on that throughout the day, and didn't get time to get a game in. After work, I bought a snowblower, because our driveway is a mess.

Anyway, I *did* have an AYD game today, and it was very fascinating. I felt a lot of pressure throughout the game. Here's the record:

Here are a couple of thoughts... Haven't reviewed with an AI, and I've also not had any sort of human review.

This *feels* like it could be an overplay. But I can't really tell what the best result for black is. During the game I couldn't either, so I played it.

Here, I read for quite some time - I just couldn't find a sequence to kill black. I thought it'd be OK to press black down on the second line. But I still felt annoyed.

The end result felt decent:

My groups were basically alive; black had a weak group in the top left; and I got a decent corner. I felt OK.

Not sure, but maybe the marked white move, above, is questionable. I think it could have been worth thinking about putting more pressure and continuing to the center where black's potential was:

Again, not sure... But It seems important in that it keeps pressure on, while reducing the black right side potential. If the right side isn't big territory, I should be OK given my top left corner territory.

Here was a decision point: do I try to keep alive with my stones, or do I solidify the top as territory? I counted the points, and it seemed that if I live in the bottom right, white's top would be enough to put white ahead.

So I went with that strategy. I feel good about that decision.

---

All in all, I feel OK about this game. My opponent played well, I thought, and I'm proud that I didn't go totally crazy when things got somewhat close, like I usually do.

Had a review from Inseong's friend, Seongjin. It seems he was surprised white won, and thought black had won. I guess I made a lot in the endgame.

He highlighted the same bad move as I did:

Well, the day of my running race came yesterday. I had been preparing for a 5k, where I'd race along with some coworkers. Back in high school, I had done a lot of running, but that was 17 years ago, and I pretty much gave up on competitive running until this year.

In high school, my personal best was 17:45, and I was usually running low 18-minute 5ks. But when I ran a 5k for the first time since then two years ago, my time was a lot slower (almost 24 minutes). Then last year, I tried again, and had something like a 23:02... Still a lot slower than I was in high school.

This year, a coworker that's really into running organized for us to all run a 5k race on November 17th. He's really into running, but seems to average around the 19-minute range (his best was something like 18:50, maybe?). Given my high school times, I made it a goal to beat him: yes, I was a lot heavier than high school, and more out of shape, but with a few months of training, I could get back on track.

So I did some 5ks to practice along the way. In August, I ran a 21:22... Still not where I needed to be, but a lot faster than the previous year's 23:02. Then in September, I tried again for a 20:48. Still, and improvement, but not under 20 minutes, yet. I really needed to get at least under 20-minutes to have a chance.

In contrast to high school, I don't have a coach, so I looked up tips online about how to improve 5k race times. A consensus seemed to emerge in doing speed workouts. So I tried to aim for 2~3 speed workouts a week, along with a distance run. One of the speed workouts would be a tempo run - at race pace for a longer distance than a typical speed workout.

I worked on that on and off, but as the days got colder, my motivation began to wane. I'd often run once near the start of the week, then *maybe* get an easy workout in around mid-week, and then I'd slack off heading into the weekend.

November 17th arrived yesterday, and driving to the race, I was angry with myself: why hadn't I trained harder? I'd have a bad result for sure. I had all of this time to train, but I kept taking it easy. I had pretty strong feelings of regret.

I came to recall a time in middle school, when I was racing for school. There was another teammate who always came in right ahead of me. At that time, by the suggestion of my father, I made a notecard that said, "I, Brian Kirby, have beaten <name-of-kid> at the <name-of-race> on <date-of-race". I'd read it to myself every day in the morning and night, as soon as I got up, and right before going to bed. When the day of the race came, I ran as usual, but didn't feel as tired as I often did. I didn't notice it, but I ran about a minute faster than usual, and ended up beating my teammate without much thought. It was an impressive display of the power of psychology.

Well, I didn't exactly use the same method for the November 17th race against my colleague. I hadn't made a notecard, and I hadn't thought about it at night before going to bed. But hey, I thought, I could at least try to psych myself up this morning before the race.

I arrived at the race, and saw my rival. And in that instant, self-doubt filled my consciousness. Here was a kid, several years my younger, about 50 pounds lighter than me, with probably 8% less body fat. And running was his passion - perhaps he liked running as much as I liked go. In what world could there exist a possibility such that I'd beat this guy?

It was a negative thought, but it was the self-talk that entered my mind prior to the race.

Shortly after, the race began. I have a fitness watch, and tracked my pace - I started out a little bit fast, but I felt good. And I was going faster than my rival. I was also on track to break 20 minutes, which has been my goal. About 2.2km into the race - not quite half way, I was still on pace, and my rival came up next to me. I said, "good job" to him, but was again filled with negativity. "I can't beat this guy. He's done under 19 minutes not that long ago," I thought. And after only a few seconds, I began to slow down - my goal was to beat 20 minutes, but if this guy was going for 18:40 or something, I wouldn't be able to keep up.

And so, the distance between my rival and I increased. As the race went on, I felt more negativity, "Well, if I'm not beating my rival," I thought, "what difference does it make what my time is?" And I had a very hard time keeping up the pace.

The end of the race came, and I finished after my rival with the slowest time for a 5k I've had this year: 21:34. Even the race in August was faster than this, which happened shortly after I started "training". Then I noticed my rival's time - he had finished in the low 20-minute range. I guess it was a slow day for everyone.

I thought to myself, then, that I had lost psychologically. It had been my goal to break 20 minutes all along, and I let the negative talk get to me. It was unfortunate, but that was the result.

Despite the sad result, now that the race is over, I feel a burden lifted. And I also feel that I'm not finished training. I don't have to be stressed about an upcoming race. But I still intend to break 20 minutes for 5k... Maybe without the extra pressure, I can lose the weight I need to get into better shape. And with any luck, my psychology will improve, too.

I feel some regret about what happened. But as I said - I'm not finished, yet. I still want to improve more.

Had another AYD game this afternoon at lunchtime. I had some issues, because I didn't realize my battery was only 2% on my laptop. So I tried a game on shinkgs for the first time, using my phone. It worked alright.

Here's the game:

My general feel of the game was that my opponent was somewhat lax in the opening. So I didn't feel like I had to do much. Somehow, I let things get a bit risky on the right side, even though I didn't need to. I thought he'd turn this into ko:

But he didn't. After that resolved, I figured I'd just live with the middle group, and it'd be enough.

I played the last game for the month in the AYD.

I'm not that proud of it, but here it is:


So this month, I had a perfect record (5 wins)... I'm kind of weak against mustwin - I lost to him before, and I think he often out reads me. I got lucky this game... It was amazing that he didn't kill my bottom right corner, and that I killed the right, and that I lived in the end. Everything lined up this game, I guess.

Anyway, that marks the end of the AYD season. I have been thinking about what to do next. I considered joining the online BIBA program. It's more expensive than Inseong's program, but it has other features (game against pro, go problems, etc.). There's also the added benefit that I haven't tried it, yet.

On the other hand, Inseong's program is more affordable... And I'm friends with Inseong, so that's another plus for the AYD.

I'll think about it a little bit more. I don't think I have to decide quite yet.

Thinking of playing some more Zelda today (breath of the wild), since my game finished early. That game is too fun...
