Life In 19x19

Hello everybody! My name is Shawn Ligocki and I started playing Go about 7 months ago (Sounds sort of like I'm introducing myself at Go Anonymous, right?) and have been pretty captivated by the game since I started! (Heh, probably not super-original for folks on this forum, but what can I say...) I live in Boston and play at the Diesel cafe (Doesn't it sound like a leather bar? Couldn't be further from the truth!) meetup every Thursday (any of you live in the area?).

I've been recording all my games since my first tournament in late October and I thought it might be fun to start posting my games here to centralize my analysis and maybe get some feedback from you all. I don't know how often I'll be able to post, but I'd love to hear any comments from any of you!

I've been improving quickly and am now 8 kyu on KGS. Just this last Sunday I went undefeated at our local tournament at 8k! But even in these games, I made many mistakes that almost cost me the games. So I know I have a lot of work to do.

My biggest goal is to become really proud of my games (I'm only really proud of one my games at this tournament). I don't have any particular rank goal in mind, but for fun let's say I'd feel quite accomplished to be AGA 4 kyu by the US Go Congress in August (Maybe I'll see some of you guys there?).

Here's my first game from the tournament. It's an even game.

I felt pretty smug at the beginning because White was letting make a gigantic moyo, but she ended up cutting up my group and then chasing my weak group throughout her moyo. I should not have lived, but she made a critical mistake.

Here are my main questions about the game:

1. What should I have done differently around instead of just pushing White to slice through my groups? Was this play reasonable up until then (I felt quite good about it!) But when White cut my groups up, I felt like I'd made a mistake.

2. Could I have played better in response to the 3-3 invasion? I was hoping to get sente out of it to invade White's corner.

3. How would it be better to have played starting around ? I don't understand very well how to play when trying to make eyeshape in my opponent's moyo and I should have died. Maybe I should have played more lightly? But I was worried that I'd lose the entire bottom-left group if I left any cutting points. I feel like I could use a lot of help on this section of the game.

Things I know I should have done better:

1. Protect locally at , White's follow up there was devastating and I could have played in sente there :/

2. Many endgame problems. After about Move 146 or so we were in Byo-yomi and I didn't realize how many weaknesses there were in the top right (or how close the game would be).

Thanks!

Hi Shawn,

Correct. Big mistakes in your shapes. Start to study Broken shapes. See also Toothpaste and Small gaps.

Thanks for the review Ed!

Those low moves at and are really helpful and I appreciate your explanation of the broken shape that I kept creating. I'll work on that in future games.

But I still don't fully understand why White would play defensively at . This move seems concerning to me:

Should I not worry because giving him a panuki in the outside is worth less than the corner?

Hi Shawn, after , B has miai of (a) and (b) -- so it is B who gets a ponnuki first:

Thanks Ed, I'll try not to be afraid of that atari next time.

Here is the second game of my tournament last week.

Overall, I felt great about my opening, I got a huge moyo and only gave White a little bit of territory (say up to ). But then White kept jumping in and trying to spoil my moyo all over the place. I can't tell if this was a bad idea (making lots of weak groups) or a good idea (playing lightly in Blacks area to spoil my moyo). I know I made a huge blunder (not connecting at ) and was saved by White making a similarly huge mistake (responding to my ko threat at White 119).

Here's what I'm curious about in the game:

1. Was a bad play? Just helping White to settle her shape? How about the rest of that corner play?
2. How about the fight from - ? I still felt good having built huge influence while giving White only small life (or is it even alive?). Should I have attacked the top group more?
3. At , should I have attacked this weak group on the left more?
4. Does White have a good response to Black 100 to save the top group? Should I have played differently to avoid the disadvantageous ko?
5. White should not have responded to my Ko threat at Black 118, right? Can I live if White connects? (I don't see how I could.)
6. Does White have any Ko threats for White 121?

Thanks!

At 175, black should play A14 and will then have miai to either capture the two stones to kill the corner, or, if white captures the one stone, then play B12 to kill.

Also, for a long time in the top right, I'm pretty sure black can kill with Q18, followed by a peep.

Note that Black can also just descend as shown below. Now 'a' and 'b' are miai for Black. White cannot achieve anything here.

Great, thanks ez4u! That descent looks much better for Black and now I can see that White has a lot of problems.

Here's a game I lost a week ago that I think I could learn a lot from. I reviewed the game with my opponent afterwards and that's the basis for most of my comments.

As always, comments are most appreciated!



My overall thoughts:
* might be in the wrong direction?
* Should not have ignored , the corner was in trouble.
* And in general after this, I should have been focused on getting out and making life with that weak corner group.

Hi Shawn, your is no problem. In fact, it's better than the kosumi variation.

If you made mistakes in the game, it's not here. It's later, in your follow-ups, etc.
Many people misunderstand which mistakes are important to fix at which levels,
and which are not important.

Thanks Ed, I thought that was good, but my opponent told me that the diagonal was better (which I thought was wrong). I appreciate your clarification here.

Hi Shawn, when in doubt, check with a reputable source. Like a pro. Not just any pro, but a good-level pro.
(How to find such resources, you may ask. That's the $1M question isn't it. Bill here is good. )

Kyu advice...
