Interesting commentary on Zen19 on $4000 computer vs. 2-dan amateur, written with kyū readers in mind.

TBH I find it hard to believe that Black is legitimately 2d looking at that game.

The computer plays a terrible opening and it should be easy for Black to take a solid lead, but then he plays a lot of submissive moves like he's scared of it... and even then he's doing fine until he tenukis when his group is obviously killable.

I think a lot of people are simply confused by the alien un-logic of computers' moves and freeze up because they're so used to relying on set patterns.

Agree, you have to get a really good start with decent AI because the opening / midgame is their weak point, when the possible gamestates start closing down they will be very good at killing weak groups and own the endgame.

there are two ways to study Life and death or tesuji problems. In case of tesuji, I used to memorize the possible variations in a problem instead of trying to come up with the solution myself. Still some take the way i did or some other try to solve and put more time on a particular problem , either way if you end up being like a dictionary then you succeed.
Interesting opinion.

It will, though. It's just a bottom-up rather than top-down approach.

Compare with learning to play an instrument. You can start by learning scales and chords and keys and harmonies and all that theory, and then apply that knowledge to learn a song.

Or you can just learn to play a bunch of songs without bothering to learn why this note sounds good here and that note sounds bad.

It may be hard to see at first how learning to play one song helps you learn other songs if you haven't been taught all the general principles, but humans are good at inductive reasoning. If you learn a bunch of songs, you will eventually notice the similarities between them, that this note usually leads to this other note unless it was preceded by that one, and so on.

When I was a kyu, I couldn't understand how dan players were generally capable of remembering their games (up until the endgame, anyway) and replaying them accurately later on, without even making any special effort during the game to memorize.

When I reached that level of strength myself, however, I realized why it came naturally, which is that you're no longer thinking in terms of individual moves, but shapes and sequences. Basically, you're just remembering what the board looked like at various key moments when you gave particular thought to a move, and all the other moves that come between those moments are then easy to interpolate.

Where amateur dans tend to go wrong - both in terms of making tactical mistakes in playing, and mistakes in remembering the game afterwards - is when you get into weird, unfamiliar shapes, where the course of play is no longer natural and you're forced to improvise on the tactical level instead of reasoning on the strategic level. But the stronger you get, the fewer situations are alien to you, and I think part of being a pro is getting to the point where nothing on the tactical level really surprises you anymore.

So yeah. Knowing the answer to one tsumego might not help you much in a game, but knowing the answer to 10,000 tsumego, if you're a "dictionary" as she puts it, will help you. Because you can prune the decision tree way way down by, as a mathematician or computer scientist would put it, "reducing to a solved problem."

I think getting better at reading and doing tsumego is all about the reducing. You do the problems so you can reduce faster, and thereby consider more poo poo in a game. If you know the answer to a problem without having to think, you can think about something else, and all of the sudden you are, virtually speaking, reading out ten moves more than you were before. If you have to keep that consciously in mind, your ability to consider other things will suffer.

The best illustration, for me, of how tsumego works at higher level was when I was working at the go club on some problems while waiting for a game. The club heavy, who is 8d on Tygem, praised my problem book because it had a problem in there that he didn't know. Reached the answer instantly, of course - but he didn't recognize the problem itself, something noteworthy enough that he was surprised about it. I guess to get really good you will wind up Knowing All the Problems.

Heh. So I just finished my first game on OGS. I'd set myself as 4d because that's what I am was and immediately regretted it when I had to give two stones to a guy calling himself 2d.

But I won. By 2.5. Crazy, crazy game. I'm sure both of us had opportunities to do better in the top left.

Yeah, I felt from the game that two stones would have been about right if I was really 100% back on my game. As it is, I was lucky to squeak through against him and would probably not win 50% of the time at two stones.

Looking at your game, it sure does seem his MO is to squeeze people into small life and build a massive central moyo eh?

Kheldragar posted:

Yeah, speaking of "dictionaries," that's a standard sequence, just one that I'd forgotten about due to my hiatus from the game. Given Black's thickness below the fight should in all fairness gone badly for me, so either B47 should have been E16 or B49 should have been F17.

How to choose A or B?
(other than "A is usual.")
AFAICT, A or B both give White the choice between living inside or pushing at d10.

I brought it up in KGS Teaching Ladder, and the answer is that White has monkey jump in the last variation. (Also, the Black d10 variation misses that White can cut directly at d11.)

I don't even know what the goal of the problem is. Is it just endgame? It doesn't seem like you can kill, since White is connected out and I don't see any way to prevent that.

Sorry about the lack of lectures, guys. My kid (one year old today!) is going through a refusing-to-sleep-in-his-crib phase. He basically just stays awake no matter what we do until we're going to bed and then will only sleep in the bed with us.

However, I just had a pretty satisfying win in my first game with my shiny new [1d] rating. To make up for the lack of lectures I decided to comment the game for you guys. There's some valuable lessons to be learned from it about exploiting aji, refusing to be pushed around, and making exchanges. I did make some mistakes, but mostly of the form that I was playing dangerously while ahead rather than taking simplifying lines that also would have led to a win, albeit a less spectacularly bloody one.

I'm actually starting to feel like I'm stronger now than I was when I quit. Probably because I'm actually enjoying the game again. I suspect frustration was holding me back before. Weirdly, my style has changed a lot, too. I used to be more of a moyo and attacking-for-profit kind of guy, and now I find myself favoring a more Korean style approach of taking solid territory in the opening and then brutally murdering something in the late middlegame.

Thanks. Reviewing one's games is of course helpful on an individual level too, so until I have the ability to do live sessions in the evenings again, I may continue commenting any of my KGS games that seem particularly interesting. A lot of them are just dumb and end because of a blunder or degenerate into a crazy fight right off the bat. I picked this one because there are a number of important strategic points to be gleaned from it (such as my sacrifices on the left, and the problems with Black's wall on the right), plus a number of pretty cool tactical sequences.

Oh, there's one thing I forgot to mention in the commentary.

At W44 I should probably first clamp at B2 as a probe. Assuming he answers at either A3 or C3, then I play D6 as in the game, happy to have forced him to make that decision first, since A3 leaves aji and C3 leaves me a big endgame move at A3.

He might resist by playing C6 instead, but then I live in the corner by capturing one stone and am okay with treating C9 lightly.

Here's what I mean: http://eidogo.com/#oHbJeP0O

Besides the fact that kgs seems to be working on an html5 client, I'd say no. You could just play on ogs or Tygem instead, which aren't optimal substitutes.

You seem to be losing the plot a lot. You start something in an area and then appear to forget what you were trying to accomplish and just go start something else. It may seem like high-level players tenuki at random, but it's never really at random. There are basically two reasons to tenuki:

(a) the local temperature has dropped because you're reached a relatively stable position, so it's now more profitable to play elsewhere, or

(b) it's not currently clear what local continuation will prove to be strategically best, so you turn elsewhere for the time being to see how the rest of the board develops before returning.
